80Vp - p output suspended load amplifier circuit is shown in the graph below.This circuit uses a high input impedance op-amp FX3140B.In dual power supply of 22V,the output will reach its peak ,which is more than 40V.The slew rate is 9V/s, the input bias current is10pA, the offset current is 0.5 pA, and the offset voltage is1mV.The load is connected between the output of the two op-amps ,whose output voltage Uo is 2U1, and the maximum output voltageis 80Vp - p. The decoupling of power supply uses 0.1 u F ceramic capacitors connecting foot 7, 4 of FX3140 with the ground in the shortest distance. A metal film resistor with the precision of 1% is used as the resistance .
