The THS1030 has been designed to give circuit developers flexibility. The analog input to the THS1030 can be either single-ended or differential. The THS1030 provides a wide selection of voltage references to match the user’s design requirements. For more design flexibility, the internal reference can be bypassed to use an external reference to suit the dc accuracy and temperature drift requirements of the application. The out-of-range output is used to monitor any out-of-range condition in THS1030’s input range. The speed, resolution, and single-supply operation of the THS1030 are suited for applications in STB, video, multimedia, imaging, high-speed acquisition, and communications. The speed and resolution ideally suit charge-couple device (CCD) input systems such as color scanners, digital copiers, digital cameras, and camcorders. A wide input voltage range between REFBS and REFTS allows the THS1030 to be applied in both imaging and communications systems. The THS1030C is characterized for operation from 0°C to 70°C, while the THS1030I is characterized for operation from −40°C to 85°C AVAILABLE OPTIONS SPECIFIED TEMPERATURE RANGE PACKAGE MARKINGS 0°C to 70°C TH1030 THS1030I −40°C to 85°C TJ1030 THS1030C 0°C to 70°C TH1030 −40°C to 85°C TJ1030 PRODUCT PACKAGE LEAD PACKAGE DESGIGNATOR† THS1030C TSSOP−28 SOP−28 PW DW THS1030I ORDERING NUMBER TRANSPORT MEDIA, QUANTITY THS1030CPW Tube, 50 THS1030CPWR Tube and Reel, 2000 THS1030IPW Tube, 50 THS1030IPWR Tube and Reel, 2000 THS1030CDW Tube, 20 THS1030CDWR Tube and Reel, 1000 THS1030IDW Tube, 20 THS1030IDWR Tube and Reel, 1000 † For the most current specification and package information, refer to the TI web site at www.ti.com.

Integral nonlinearity refers to the deviation of each individual code from a line drawn from zero to full scale. The point used as zero occurs 1/2 LSB before the first code transition. The full-scale point is defined as a level 1/2 LSB beyond the last code transition. The deviation is measured from the center of each particular code to the true straight line between these two endpoints. 3. An ideal ADC exhibits code transitions that are exactly 1 LSB apart. DNL is the deviation from this ideal value. Therefore this measure indicates how uniform the transfer function step sizes are. The ideal step size is defined here as the step size for the device under test (i.e., (last transition level – first transition level) ÷ (2 n – 2)). Using this definition for DNL separates the effects of gain and offset error. A minimum DNL better than –1 LSB ensures no missing codes. 4. Offset error is defined as the difference in analog input voltage – between the ideal voltage and the actual voltage – that will switch the ADC output from code 0 to code 1. The ideal voltage level is determined by adding the voltage corresponding to 1/2 LSB to the bottom reference level. The voltage corresponding to 1 LSB is found from the difference of top and bottom references divided by the number of ADC output levels (1024). 5. Gain error is defined as the difference in analog input voltage – between the ideal voltage and the actual voltage – that will switch the ADC output from code 1022 to code 1023. The ideal voltage level is determined by subtracting the voltage corresponding to 1.5 LSB from the top reference level. The voltage corresponding to 1 LSB is found from the difference of top and bottom references divided by the number of ADC output levels (1024). dynamic performance (See Note 6) PARAMETER TEST CONDITIONS f = 3.5 MHz ENOB MIN TYP 8.4 9 f = 3.5 MHz, AVDD = 5 V Effective number of bits Spurious free dynamic range 7.7 56 64.6 f = 15 MHz 48.5 −60 f = 3.5 MHz, AVDD = 5 V −66.9 f = 15 MHz −47.5 f = 15 MHz, AVDD = 5 V f = 3.5 MHz SNR f = 3.5 MHz, AVDD = 5 V Signal-to-noise and distortion f = 15 MHz f = 15 MHz, AVDD = 5 V NOTES: 6.

Connecting the MODE pin to one of three voltages, AGND, AVDD or AVDD/2 sets up operating configurations. The three settings open or close internal switches to select one of the three basic methods of ADC reference generation. Depending on the user’s choice of operating configuration, the ADC reference voltages may come from the internal reference buffer or may be fed from completely external sources. Where the reference buffer is employed, the user can choose to drive it from the onboard reference generator (ORG), or may use an external voltage source. A specific configuration is selected by connections to the REFSENSE, VREF, REFTS and REFBS, and REFTF and REFBF pins, along with any external voltage sources selected by the user. The ADC core drives out through output buffers to the data pins D0 to D9. The output buffers can be disabled by the OE pin. A single, sample-rate clock (30 MHz maximum) is required at pin CLK. The analog input signal is sampled on the rising edge of CLK, and corresponding data is output after following third rising edge. The STBY pin controls the THS1030 power down. The user-chosen operating configuration and reference voltages determine what input signal voltage range the THS1030 can handle. The following sections explain: D The internal signal flow of the device, and how the input signal span is related to the ADC reference voltages D The ways in which the ADC reference voltages can be buffered internally, or externally applied D How to set the onboard reference generator output, if required, and several examples of complete configurations signal processing chain (sample and hold, ADC) Figure 11 shows the signal flow through the sample and hold unit to the ADC core.

POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 13                SLAS243E − NOVEMBER 1999 − REVISED DECEMBER 2003 PRINCIPLES OF OPERATION ADC reference generation The THS1030 has three primary modes of ADC reference generation, selected by the voltage level applied to the MODE pin. Connecting the MODE pin to AGND gives full external reference mode. In this mode, the user supplies the ADC reference voltages directly to pins REFTF and REFBF. This mode is used where there is need for minimum power drain or where there are very tight tolerances on the ADC reference voltages. This mode also offers the possibility of Kelvin connection of the reference inputs to the THS1030 to eliminate any voltage drops from remote references that may occur in the system. Only single-ended input is possible in this mode. Connecting the MODE pin to AVDD/2 gives differential mode. In this mode, the ADC reference voltages REFTF and REFBF are generated by the internal reference buffer from the voltage applied to the VREF pin. This mode is suitable for handling differentially presented inputs, which are applied to the AIN and REFTS/REFBS pins. A special case of differential mode is center span mode, in which the user applies a single-ended signal to AIN and applies the mid-scale input voltage (VM) to the REFTS and REFBS pins. Connecting the MODE pin to AVDD gives top/bottom mode. In this mode, the ADC reference voltages REFTF and REFBF are generated by the internal reference buffer from the voltages applied to the REFTS and REFBS pins. Only single-ended input is possible in top/bottom mode. When MODE is connected to AGND, the internal reference buffer is powered down, its inputs and outputs disconnected, and REFTS and REFBS internally connected to REFTF and REFBF respectively. These nodes are connected by the user to external sources to provide the ADC reference voltages. The internal connections are designed for use in kelvin connection mode (Figure 14). When using external reference mode as shown in Figure 13, REFTS must be shorted to REFTF and REFBS must be shorted to REFBF externally. The mean of REFTF and REFBF must be equal to AVDD/2.

This is achieved by setting pin 17 (STBY) to 1. In power-down mode, the device typically consumes less than 1 mW of power (from AVDD and DVDD) in either top/bottom mode or center-span mode. On power up, the THS1030 typically requires 5 ms of wake-up time before valid conversion results are available in either top/bottom or center span modes. Disabling the ORG in applications where the ORG output is not required can also reduce power dissipation by 1 mA analog IDD. This is achieved by connecting the REFSENSE pin to AVDD. output format and digital I/O While the OE pin is held low, ADC conversion results are output at pins D0 (LSB) to D9 (MSB).

The external source driving AIN must be able to charge and settle into CSAMPLE and the CP1 and CP2 strays to within 0.5 LSB error while sampling (CLK pin low) to achieve full ADC resolution.

The total charge transferred depends on the voltage at AIN and is given by: Q CHARGING + (AIN * V LAST ) C . S (7) For a fixed voltage at AIN, so that AIN and VLAST do not change between samples, the maximum amount of charge transfer occurs at AIN = FS− (charging current flows out of THS1030) and AIN = FS+ (current flows into THS1030). If AIN is held at the voltage FS+, VLAST = [(FS+) + VM]/2, giving a maximum transferred charge: Q(FS) + (FS )) * [(FS )) ) VM] 2 C + S + (1ń4 of the input voltage span) C [(FS )) * VM] C S 2 (8) S If the input voltage changes between samples, then the maximum possible charge transfer is Q(max) + 3 Q(FS) (9) which occurs for a full-scale input change (FS+ to FS− or FS− to FS+) between samples. The charging current pulses can make the AIN source jump or ring, especially if the source is slightly inductive at high frequencies. Inserting a small series resistor of 20 Ω or less in the input path can damp source ringing (see Figure 31). This resistor can be made larger than 20 Ω if reduced input bandwidth or distortion performance is acceptable. R < 20 Ω AIN VS Figure 28. Damping Source Ringing Using a Small Resistor 24 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265                SLAS243E − NOVEMBER 1999 − REVISED DECEMBER 2003 PRINCIPLES OF OPERATION equivalent input resistance at AIN and ac-coupling to AIN Some applications may require ac-coupling of the input signal to the AIN pin. Such applications can use an ac-coupling network such as shown in Figure 29. AVDD R(Bias1) Cin AIN R(Bias2) Figure 29. AC-Coupling the Input Signal to the AIN Pin Note that if the bias voltage is derived from the supplies, as shown in Figure 29, then additional filtering should be used to ensure that noise from the supplies does not reach AIN. Working with the input current pulse equations given in the previous section is awkward when designing ac-coupling input networks. For such design, it is much simpler to model the AIN input as an equivalent resistance, RAIN, from the AIN pin to a voltage source VM where VM = (REFTS + REFBS)/2 and RAIN = 1 / (CS x fclk) where fclk is the CLK frequency. The high-pass −3 dB cutoff frequency for the circuit shown in Figure 29 is: f (*3 dB) + ǒ2 1 p R Ǔ tot IN (10) where RINtot is the parallel combination of Rbias1, Rbias2, and RAIN. This approximation is good provided that the clock frequency, fclk, is much higher than f(−3 dB). Note also that the effect of the equivalent RAIN and VM at the AIN pin must be allowed for when designing the bias network dc level. details The above value for RAIN is derived by noting that the average AIN voltage must equal the bias voltage supplied by the ac coupling network. The average value of VLAST in equation 8 is thus a constant voltage VLAST = V(AIN bias) – VM For an input voltage Vin at the AIN pin, Qin = (Vin – VLAST) x Cs Provided that f (−3 dB) is much lower than fclk, a constant current flowing over the clock period can approximate the input charging pulse Iin = Qin / tclk = Qin x fclk = (Vin – VLAST) x CS x fclk POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 25                SLAS243E − NOVEMBER 1999 − REVISED DECEMBER 2003 PRINCIPLES OF OPERATION details (continued) The ac input resistance RAIN is then RAIN = dIin / dVin = 1 / (dVin / dIin) = 1 / (CS x fclk) driving the VREF pin (differential mode) Figure 30 shows the equivalent load on the VREF pin when driving the internal reference buffer via this pin (MODE = AVDD/2 and REFSENSE = AVDD ).

Equivalent Circuit of REFTF and REFBF Inputs Note the need for off-chip decoupling. driving the clock input Obtaining good performance from the THS1030 requires care when driving the clock input. Different sections of the sample-and-hold and ADC operate while the clock is low or high. The user should ensure that the clock duty cycle remains near 50% to ensure that all internal circuits have as much time as possible in which to operate. The CLK pin should be driven from a low jitter source for best dynamic performance. To maintain low jitter at the CLK input, any clock buffers external to the THS1030 should have fast rising edges. Use a fast logic family such as AC or ACT to drive the CLK pin, and consider powering any clock buffers separately from any other logic on the PCB to prevent digital supply noise appearing on the buffered clock edges as jitter. The CLK input threshold is nominally around AVDD/2—ensure that any clock buffers have an appropriate supply voltage to drive above and below this level. digital output loading and circuit board layout The THS1030 outputs are capable of driving rail-to-rail with up to 20 pF of load per pin at 30-MHz clock and 3-V digital supply. Minimizing the load on the outputs will improve THS1030 signal-to-noise performance by reducing the switching noise coupling from the THS1030 output buffers to the internal analog circuits. The output load capacitance can be minimized by buffering the THS1030 digital outputs with a low input capacitance buffer placed as close to the output pins as physically possible, and by using the shortest possible tracks between the THS1030 and this buffer. Noise levels at the output buffers, and hence coupling to the analog circuits within THS1030, becomes worse as the THS1030 digital supply voltage is increased. Where possible, consider using the lowest DVDD that the application can tolerate. Use good layout practices when designing the application PCB to ensure that any off-chip return currents from the THS1030 digital outputs (and any other digital circuits on the PCB) do not return via the supplies to any sensitive analog circuits. The THS1030 should be soldered directly to the PCB for best performance. Socketing the device will degrade performance by adding parasitic socket inductance and capacitance to all pins. 28 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265                SLAS243E − NOVEMBER 1999 − REVISED DECEMBER 2003 PRINCIPLES OF OPERATION user tips for obtaining best performance from the THS1030 D D D D D D Voltages on AIN, REFTF and REFBF and REFTS and REFBS must all be inside the supply rails. ORG modes offer the simplest configurations for ADC reference generation. Choose differential input mode for best distortion performance. Choose a 2-V ADC input span for best noise performance. Choose a 1-V ADC input span for best distortion performance. If the ORG is not used to provide ADC reference voltages, its output may be used for other purposes in the system. Care should be taken to ensure noise is not injected into the THS1030. D Use external voltage sources for ADC reference generation where there are stringent requirements on accuracy and drift. D Drive clock input CLK from a low-jitter, fast logic stage, with a well-decoupled power supply and short PCB traces. TLC876 mode The THS1030 is pin compatible with the TI TLC876 and thus enables users of TLC876 to upgrade to higher speed by dropping the THS1030 into their sockets. Grounding the 1876M pin effectively puts the THS1030 into 876 mode using the external ADC reference. The MODE pin should either be grounded or left floating. The REFSENSE pin is connected to DVDD when the THS1030 is dropped into a TLC876 socket. For DVDD = 5-V applications, this will disable the ORG. For TLC876 applications using DVDD = 3.3 V, the VREF pin will be driven to AVSS. In TLC876/AD876 mode, the pipeline latency is increased to 3.5 clock cycles to match the TLC876 latency.
