Low Distortion Rail-to-Rail Output Swing GENERAL DESCRIPTION The AD8051 (single), AD8052 (dual), and AD8054 (quad) are low cost, high speed, voltage feedback amplifiers. The amplifiers operate on +3 V, +5 V, or ±5 V supplies at low supply current. They have true single-supply capability with an input voltage range extending 200 mV below the negative rail and within 1 V of the positive rail. Despite their low cost, the AD8051/AD8052/AD8054 provide excellent overall performance and versatility. The output voltage swings to within 25 mV of each rail, providing maximum output dynamic range with excellent overdrive recovery. Rev.

The maximum safe junction temperature for plastic encapsulated devices is determined by the glass transition temperature of the plastic, approximately 150°C. Temporarily exceeding this limit can cause a shift in parametric performance due to a change in the stresses exerted on the die by the package. Exceeding a junction temperature of 175°C for an extended period can result in device failure. While the AD8051/AD8052/AD8054 are internally shortcircuit protected, this cannot be sufficient to guarantee that the maximum junction temperature (150°C) is not exceeded under all conditions. To ensure proper operation, it is necessary to observe the maximum power derating curves. 2.5 MAXIMUM POWER DISSIPATION (W) 2.0 SOIC-14 TSSOP-14 See Table 5. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied.

The process is dielectrically isolated to eliminate the parasitic and latch-up problems caused by junction isolation. These features allow the construction of high frequency, low distortion amplifiers with low supply currents. This design uses a differential output input stage to maximize bandwidth and headroom (see Figure 40). The smaller signal swings required on the first stage outputs (nodes SIP, SIN) reduce the effect of nonlinear currents due to junction capacitances and improve the distortion performance. This design achieves harmonic distortion of −80 dBc @ 1 MHz into 100 Ω with VOUT = 2 V p-p (gain = +1) on a single 5 V supply.

Exceeding these values do not cause phase reversal; however, the input ESD devices begin to conduct if the input voltages exceed the rails by greater than 0.5 V. During this overdrive condition, the output stays at the rail. The rail-to-rail output range of the AD8051/AD8052/AD8054 is provided by a complementary common emitter output stage. High output drive capability is provided by injecting all output stage predriver currents directly into the bases of the output devices Q8 and Q36. Biasing of Q8 and Q36 is accomplished by I8 and I5, along with a common-mode feedback loop (not shown). This circuit topology allows the AD8051/AD8052 to drive 45 mA of output current and allows the AD8054 to drive 30 mA of output current with the outputs within 0.5 V of the supply rails.

The amplifier must recover from this overdrive condition. As shown in Figure 41, the AD8051/AD8052/ AD8054 recover within 60 ns from negative overdrive and within 45 ns from positive overdrive.

Overdrive Recovery DRIVING CAPACITIVE LOADS Consider the AD8051/AD8052 in a closed-loop gain of +1 with +VS = 5 V and a load of 2 kΩ in parallel with 50 pF. Figure 42 and Figure 43 show their frequency and time domain responses, respectively, to a small-signal excitation. The capacitive load drive of the AD8051/AD8052/AD8054 can be increased by adding a low value resistor in series with the load. Figure 44 and Figure 45 show the effect of a series resistor on the capacitive drive for varying voltage gains. As the closed-loop gain is increased, the larger phase margin allows for larger capacitive loads with less peaking. Adding a series resistor with lower closed-loop gains accomplishes the same effect. For large capacitive loads, the frequency response of the amplifier is dominated by the roll-off of the series resistor and the load capacitance. 8 6 4 2 100 RG RF RS 50Ω CL VOUT 10 VIN 100mV STEP 1 2 3 ACL (V/V) 4 5 6 Figure 44.

Proper RF design techniques and low parasitic component selection are necessary. The PCB should have a ground plane covering all unused portions of the component side of the board to provide a low impedance path. The ground plane should be removed from the area near the input pins to reduce parasitic capacitance. Chip capacitors should be used for supply bypassing. One end should be connected to the ground plane and the other within 3 mm of each power pin. An additional large (4.7 μF to 10 μF) tantalum electrolytic capacitor should be connected in parallel, but not necessarily so close, to supply current for fast, large signal changes at the output. The feedback resistor should be located close to the inverting input pin to keep the parasitic capacitance at this node to a minimum. Parasitic capacitance of less than 1 pF at the inverting input can significantly affect high speed performance. Stripline design techniques should be used for long signal traces (greater than about 25 mm). These should be designed with a characteristic impedance of 50 Ω or 75 Ω and be properly terminated at each end. GAIN (dB) noise bandwidth of the analog signal before analog-to-digital conversion. Note that the unused amplifier’s inputs should be tied to ground.

This converter is designed to convert I and Q signals in communications systems. In this application, only the I channel is being driven. The I channel is enabled by applying a logic high to SELECT (Pin 13). The AD8051 is running from a dual supply and is configured for a gain of +2. The input signal is terminated in 50 Ω and the output is 2 V p-p, which is the maximum input range of the AD9201. The 22 Ω series resistor limits the maximum current that flows and helps to lower the distortion of the ADC. The AD9201 has differential inputs for each channel. These are designated the A and B inputs. The B inputs of each channel are connected to VREF (Pin 22), which supplies a positive reference of 2.5 V. Each of the B inputs has a small low-pass filter that also helps to reduce distortion. The output of the op amp is ac-coupled into INA-I (Pin 16) via two parallel capacitors to provide good high frequency and low frequency coupling. The 1 kΩ resistor references the signal to VREF that is applied to INB-I. Thus, INA-I swings both positive and negative with respect to the bias voltage applied to INB-I. With the sampling clock running at 20 MSPS, the analog-todigital output was analyzed with a digital analyzer. Two input frequencies were used, 1 MHz and 9.5 MHz, which is just short of the Nyquist frequency. These signals were well filtered to minimize any harmonics. Figure 48 shows the FFT response of the ADC for the case of a 1 MHz analog input. The SFDR is 71.66 dB, and the analog-todigital is producing 8.8 ENOB (effective number of bits). When the analog frequency was raised to 9.5 MHz, the SFDR was 0.33µF +5V 0.1µF 3 7 reduced to −60.18 dB and the ADC operated with 8.46 ENOBs as shown in Figure 49.

However, for some functions, such as analog-todigital conversion, it is not desirable to have the sync pulses on the video signal. These pulses reduce the dynamic range of the video signal and do not provide any useful information for such a function. A sync stripper removes the synchronizing pulses from a video signal while passing all the useful video information. Figure 51 shows a practical single-supply circuit that uses only a single AD8051. It is capable of directly driving a reverse terminated video line. VIDEO WITH SYNC VIDEO WITHOUT SYNC dynamic swing requirements are a signal that is mostly low but goes high with a duty cycle that is a small fraction of a percent, and the other extreme defined by the opposite condition. The worst case of composite video is not quite this demanding. One bounding condition is a signal that is mostly black for an entire frame but has a white (full amplitude) minimum width spike at least once in a frame. The other extreme is for a full white video signal. The blanking intervals and sync tips of such a signal have negative-going excursions in compliance with the composite video specifications. The combination of horizontal and vertical blanking intervals limit such a signal to being at the highest (white) level for a maximum of about 75% of the time. As a result of the duty cycles between the two extremes previously presented, a 1 V p-p composite video signal that is multiplied by a gain of 2 requires about 3.2 V p-p of dynamic voltage swing at the output for an op amp to pass a composite video signal of arbitrarily varying duty cycle without distortion. Some circuits use a sync tip clamp to hold the sync tips at a relatively constant level to lower the amount of dynamic signal swing required. However, these circuits can have artifacts, such as sync tip compression, unless they are driven by a source with a very low output impedance. The AD8051/AD8052/AD8054 have adequate signal swing when running on a single 5 V supply to handle an ac-coupled composite video signal. The input to the circuit in Figure 52 is a standard composite (1 V p-p) video signal that has the blanking level at ground. The input network level shifts the video signal by means of ac coupling. The noninverting input of the op amp is biased to half of the supply voltage. The feedback circuit provides unity gain for the dc-biasing of the input and provides a gain of 2 for any signals that are in the video bandwidth. The output is ac-coupled and terminated to drive the line. The capacitor values were selected for providing minimum tilt or field time distortion of the video signal. These values would be required for video that is considered to be studio or broadcast quality. However, if a lower consumer grade of video, sometimes referred to as consumer video, is all that is desired, the values and the cost of the capacitors can be reduced by as much as a factor of five with minimum visible degradation in the picture. 5V 4.99kΩ 4.99kΩ COMPOSITE VIDEO IN RT 75Ω 47µF + 10kΩ 2 VBLANK GROUND 0.4V 3V OR 5V 0.1µF VIN 3 7 GROUND + 10µF TO A/D 100Ω AD8051 2 4 6 R2 1kΩ R1 1kΩ 0.8V (OR 2 × VBLANK ) 01062-051 Figure 51. Sync Stripper The video signal plus sync is applied to the noninverting input with the proper termination. The amplifier gain is set to 2 via the two 1 kΩ resistors in the feedback circuit. A bias voltage must be applied to R1 so that the input signal has the sync pulses stripped at the proper level. The blanking level of the input video pulse is the desired place to remove the sync information. This level is multiplied by 2 by the amplifier. This level must be at ground at the output for the sync stripping action to take place. Since the gain of the amplifier from the input of R1 to the output is −1, a voltage equal to 2 × VBLANK must be applied to make the blanking level come out at ground. SINGLE-SUPPLY COMPOSITE VIDEO LINE DRIVER Many composite video signals have their blanking level at ground and have video information that is both positive and negative. Such signals require dual-supply amplifiers to pass them. However, by ac level shifting, a single-supply amplifier can be used to pass these signals. The following complications can arise from such techniques. Signals of bounded peak-to-peak amplitude that vary in duty cycle require larger dynamic swing capacity than their (bounded) peak-to-peak amplitude after they are ac-coupled.
