High-Voltage Amplifier ICs

High-Voltage General-Purpose Op Amp

A general-purpose high-voltage op amp designed in a BCD process, aimed at piezo and actuator drive, instrumentation and high-common-mode measurement.

  • Supply: ±4 V to ±40 V
  • Output swing: ±37 V with ±40 V supplies
  • Unity-gain bandwidth: 1 MHz

High-Voltage Amplifier ICs

High-Voltage Capacitive-Load Amplifier

A high-voltage analog amplifier design for small capacitive loads, including possible optical MEMS mirror-control applications.

  • Output target: up to 200 V, unipolar, with adequate supply headroom
  • Source / sink targets: 150 / 40 µA (small-capacitance charging/discharging goals)

High-Voltage Amplifier ICs

High-Voltage Sample-and-Hold Amplifier Circuits

Analog circuits that capture and retain a voltage, then amplify the held signal to a positive high-voltage output. The held value drifts gradually, so periodic refresh is required.

  • Sample-and-hold and high-voltage amplifier circuit design
  • Output target: up to 295 V at a 300 V high-voltage rail
  • Capacitive-load target: 0–3 nF per output
