The AV-110 family of variable-gain linear amplifiers is designed for driving high impedance loads with peak-to peak output voltages as high as 1000 Volts.Model AV-110A-PS provides up to +/-500V (i.e., 1000 Volts peak-to-peak), with a bandwidth of DC to 3 kHz, a 35 us rise time, and gain variable (by a ten-turn control) from x1 to x250.
