This can occur when the voltage applied at the input of the amplifier exceeds the maximum common-mode voltage. Phase reversal happens when the part is configured in the gain of 1. Most JFET amplifiers invert the phase of the input signal if the input exceeds the common-mode input. Phase reversal is a temporary behavior of the ADA4000-x family. Each part returns to normal operation by bringing back the commonmode voltage. The cause of this effect is saturation of the input stage, which leads to the forward-biasing of a drain-gate diode. In noninverting applications, a simple fix for this is to insert a series resistor between the input signal and the noninverting terminal of the amplifier. The value of the resistor depends on the application, because adding a resistor adds to the total input noise of the amplifier. The total noise density of the circuit is The advantage of this compensation method is that the swing at the output is not reduced because RS is out of the feedback network, and the gain accuracy does not change. Depending on the capacitive loading of the circuit, the values of RS and CS change, and the optimum value can be determined empirically. In Figure 31, the oscilloscope image shows the output of the ADA4000-x family in response to a 400 mV pulse. The circuit is configured in the unity gain configuration with 500 pF in parallel with 10 kΩ of load capacitive.

RS is the source resistance at the noninverting terminal. k is Boltzmann’s constant (1.38 × 10−23 J/K). T is the ambient temperature in Kelvin (T = 273 + °C). Figure 31. Capacitive Load Drive Without Snubber Network In general, it is good practice to limit the input current to less than 5 mA to avoid driving a great deal of current into the amplifier inputs. When the snubber circuit is used, the overshoot is reduced from 30% to 6% with the same load capacitance. Ringing is virtually eliminated, as shown in Figure 32. In this circuit, RS is 41 Ω and CS is 10 nF. However, as with most amplifiers, driving larger capacitive loads in a unity gain configuration can cause excessive overshoot and ringing. A simple solution to this problem is to use a snubber network (see Figure 30). +15V 3 U1 0 SNUBBER NETWORK V– –15V 1 RS CS CL 500pF 0 RL 10kΩ 05791-031 ADA4000-1 2 TIME (1µs/DIV) Figure 32.

A | Page 10 of 16 05791-033 The ADA4000-1/ADA4000-2/ADA4000-4 are stable at all gains in both inverting and noninverting configurations. The parts are capable of driving up to 1000 pF of capacitive loads without oscillations in unity gain configurations.

SETTLING TIME Settling time is the amount of time it takes the amplifier output to reach and remain within a percentage of its final value. This is an important parameter in data acquisition systems. Because most bipolar DAC converters have current output, an external op amp is required to convert the current to voltage. Therefore, the amplifier settling time plays a role in the total settling time of the output signal. A good approximation for the total settling time is (t S DAC )2 + (t S AMP )2 The ADA4000-1/ADA4000-2/ADA4000-4 settle to within 0.1% of their final value in less than 1.2 μs. The settling time has been tested by using the configuration circuit in Figure 34. 05791-035 200mV/DIV 200ns/DIV Figure 33.
