LTC1650 Low Glitch 16-Bit Voltage Output DAC U FEATURES ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ DESCRIPTIO The LTC®1650 is a deglitched rail-to-rail voltage output 16-bit digital-to-analog converter (DAC) available in a 16-pin narrow SO package. It has 16-bit monotonicity over temperature and includes a rail-to-rail output buffer amplifier and an easy to use three-wire cascadable serial interface. The LTC1650 operates with dual ±5V supplies. 16-Bit Monotonic Over Temperature Low Glitch Impulse: 2nV-s Low Noise: 30nV/√Hz Buffered Rail-to-Rail Voltage Output Low Power: 50mW from ±5V Supplies Unipolar or Bipolar Output (0V to VREF or ±VREF) 4-Quadrant Multiplying Capability Asynchronous Clear to User-Defined Voltage Power-On Reset Three-Wire SPI and MICROWIRETM Compatible Serial Interface Schmitt Trigger On CLK Input Allows Direct Optocoupler Interface 16-Pin Narrow SO Package With REFLO = 0V and REFHI = VREF, the output will swing from 0V to VREF in unipolar mode or ±VREF in bipolar mode. The LTC1650 has excellent accuracy over its full operating temperature range along with very low power dissipation of 50mW with dual ±5V supplies. This, along with the small outline package, makes it the most flexible high resolution digital-to-analog converter available today. U APPLICATIO S ■ ■ ■ ■ ■ The LTC1650 has a fast settling time of 4µs to 16 bits and a low midscale glitch of under 2nV-s. This makes the LTC1650 ideal for waveform generation or other applications where output dynamic performance is important.

The output will swing from REFLO to REFHI in unipolar mode and from (2 • REFLO – REFHI) to REFHI in bipolar mode. VRST (Pin 2): The user-defined voltage to which the output gets reset when CLR is active, when any of the supplies drop below 2.5V or when the part powers-up. The output will stay at this voltage until a new code is loaded into the DAC register. DVDD (Pin 3): The Digital Positive Supply Input. 4.75V ≤ DVDD ≤ 5.25V. 6 DGND (Pin 4): Digital Ground. DIN (Pin 5): The TTL Level Input for the Serial Interface Data. Data on the DIN pin is latched into the shift register on the rising edge of the serial clock. Data is loaded as one 16-bit word, MSB first. DOUT (Pin 6): The output of the shift register that becomes valid on the rising edge of the serial clock. CLK (Pin 7): The TTL Level Input for the Serial Interface Clock. LTC1650 U U U PI FU CTIO S CS/LD (Pin 8): The TTL Level Input for the Serial Interface Enable and Load Control. When CS/LD is low, the CLK signal is enabled so the data can be clocked in. When CS/LD is pulled high, data is loaded from the shift register into the DAC register, updating the DAC output. REFLO F/REFLO S (Pins 12, 13): The Force and Sense Pin for the Lower Reference Input. This should nominally be tied to ground. This pin can swing from – 1V to 1V. CLR (Pin 9): The DAC is cleared to VRST when this pin is pulled low. It should be logic high for normal operation. AVDD (Pin 15): The Analog Positive Supply Input. 4.75V ≤ AVDD ≤ 5.25V. Requires a bypass capacitor to ground. RSTOUT (Pin 10): The logic output pin that goes active when any of the supplies drop below 2.5V. This pin is active low. UNI/BIP (Pin 16): The Unipolar/Bipolar Selection Pin. For unipolar operation, tie this pin to VOUT and for bipolar operation, tie this pin the REFHI. AVSS (Pin 14): The Analog Negative Supply Input. – 5.25V ≤ AVSS ≤ – 4.75V. Requires a bypass capacitor to ground. REFHI (Pin 11): The Reference Input Pin. The DAC is capable of 4-quadrant multiplying; this pin can swing from 4.5V to – 4V.

It defines the number of DAC output states (2n) that divide the full-scale range. The resolution does not imply linearity. DNL is the difference between the measured change and the ideal 1LSB change between any two adjacent codes. The DNL error between any two codes is calculated as follows: Full-Scale Voltage (VFS) This is the output of the DAC when all bits are set to 1. The output will swing from REFLO to REFHI in unipolar mode and from (2 • REFLO – REFHI) to REFHI when in bipolar mode. Voltage Offset Error (VOS) This is the voltage at the output when the DAC is loaded with all zeros. Least Significant Bit (LSB) One LSB is the ideal voltage difference between two successive codes. LSB = (VFS – VOS)/(2n – 1) = (VFS – VOS)/65535 DNL = (∆VOUT – LSB)/LSB ∆VOUT = The measured voltage difference between two adjacent codes. Gain Error (GE) Gain error is the difference between the full-scale output of a DAC from its ideal full-scale value after offset error has been adjusted for. Bipolar Zero Error When configured for bipolar output and with REFLO tied to 0V, the LTC1650 output should be 0V with (100…00) loaded in. Any deviation from 0V at this code is called bipolar zero error. Bipolar Negative Full-Scale Error Integral Nonlinearity (INL) Endpoint INL is the maximum deviation from a straight line passing through the endpoints of the DAC transfer curve. It is measured after adjusting out gain and offset error for the DAC. 8 This is the offset error of the LTC1650 in bipolar mode. LTC1650 U OPERATIO Serial Interface The data on the DIN input is loaded into the shift register on the rising edge of the clock. Data is loaded as one 16-bit word, MSB first. The DAC register loads the data from the shift register when CS/LD is pulled high. The clock is disabled internally when CS/LD is high. Note: CLK must be low before CS/LD is pulled low to avoid an extra internal clock pulse. The buffered output of the 16-bit shift register is available on the DOUT pin which swings from DGND to DVDD. Multiple LTC1650s may be daisy-chained together by connecting the DOUT pin to the DIN pin of the next chip while the clock and CS/LD signals remain common to all chips in the daisy chain. The serial data is clocked to all of the chips, then the CS/LD signal is pulled high to update all of them simultaneously. When CLR is pulled low or when the part powers up, the output connects through an internal pass gate to VRST and will go to whatever voltage is on VRST. When any of three supplies (DVDD, AVDD, |AVSS|) goes below 2.5V, the RSTOUT pin goes low and stays low as long as the supply is below 2.5V. The power-on reset is also activated when one of the supplies drops below 2.5V and the output is then connected to VRST. The output connects to VRST when any of three conditions occur: CLR goes low, the part powers up or one of the supplies drops below 2.5V. This condition exists as long as CS/LD is low. As soon as CS/LD goes high, the DAC register is loaded with the data in the shift register and the output will settle to its new value. Voltage Output The LTC1650 rail-to-rail buffered output can source or sink 5mA over the entire operating temperature range. The output is specified to swing up to ±4.5V on ±4.75V supplies with VOUT unloaded. (For typical output swing at various load currents, refer to the typical curve “Minimum Supply Headroom for Full Output Swing vs Load Current.”) The buffer amplifier can drive 1000pF without going into oscillation. The LTC1650 has a deglitched voltage output. The midscale glitch is less than 2nV-s. The digital feedthrough is about 0.05nV-s. Output Ranges The LTC1650 is capable of unipolar or bipolar output swing. When the UNI/BIP pin is connected to VOUT the part is configured for unipolar operation and the output will swing from REFLO to REFHI. When UNI/BIP is connected to REFHI the part is configured in bipolar mode and the output will swing from (2 • REFLO – REFHI) to REFHI and will be at REFLO at midscale. With REFLO = 0V the output swing is ±REFHI in bipolar mode and 0V to REFHI in unipolar mode. 9 LTC1650 U TYPICAL APPLICATIO 16-Bit Industrial Process Controller 6V TO 30V 5V IN LT1019-4.5 0.1µF 5V 0.1µF 4.5V REFHI AVDD DVDD UNI/BIP CLK DIN CS/LD µP LTC1650 VOUT CLR CONTROL VOLTAGE 0V TO 4.5V (69µV/LSB) RSTOUT DOUT REFLO F/S DGND AVSS VRST –5V 0.1µF 1650 TA03 10 LTC1650 U PACKAGE DESCRIPTION N Package 16-Lead PDIP (Narrow .300 Inch) (Reference LTC DWG # 05-08-1510) 0.770* (19.558) MAX 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 0.255 ± 0.015* (6.477 ± 0.381) 0.130 ± 0.005 (3.302 ± 0.127) 0.300 – 0.325 (7.620 – 8.255) 0.020 (0.508) MIN 0.009 – 0.015 (0.229 – 0.381) ( +0.035 0.325 –0.015 8.255 +0.889 –0.381 0.045 – 0.065 (1.143 – 1.651) ) 0.065 (1.651) TYP 0.125 (3.175) MIN 0.018 ± 0.003 (0.457 ± 0.076) 0.100 (2.54) BSC *THESE DIMENSIONS DO NOT INCLUDE MOLD FLASH OR PROTRUSIONS.
