... The AD706 also achieves the microvolt offset voltage and low noise characteristics of a precision bipolar input amplifier. Since it has < 200 pA of bias current, the AD706 does not require the commonly used “balancing” resistor. Furthermore, the current noise is only 50 fA/√Hz, which makes this amplifier usable with very high source impedances. At 600 A max supply current (per amplifier), the AD706 is well suited for today’ ...

... Figure 5b. Unity Gain Inverter Large Signal Pulse Response 1,000 pF L Figure 6 shows an in-amp circuit that has the obvious advantage of requiring only one AD706, rather than three op amps, with subsequent savings in cost and power consumption. The transfer function of this circuit (without − ...

... Hz, 4-Pole, Active Filter Figure 7 shows the AD706 in an active filter application. An important characteristic of the AD706 is that both the input bias current, input offset current, and their drift remain low over most of the op amp’s rated temperature range. Therefore, for most applications, there is no need to use the normal balancing resistor ...
