AHVAPN1800V20MABN, ±1800V bipolar high voltage amplifier
The AHVAPN1800V20MABN is a bipolar high voltage amplifier and piezo driver. It amplifies an analog input of −10V to +10V into a high voltage output of ±1800V, with up to 20mA of output current. A built-in DC-DC converter makes ±1900V rails from a single 24V input, so no external high voltage supply is needed.
With a slew rate of 2000V/µs at open load and 15kHz bandwidth at 100pF, it can drive piezo actuators and other capacitive loads with fast, clean waveforms. A front-panel knob adds a DC bias of −10V to +10V. Three LEDs show that the 24V input is inside the 23V to 25V window, that the high voltage rails are good, and that the control loop works, i.e. HVO(t) = 180 × VIN(t).
Typical applications: piezoelectric transducers and actuators, mass spectrometers, electrostatic precipitators, electrophoresis experiments and high voltage storage capacitors.

A 24V DC supply (23V to 25V). The amplifier draws up to 4A and 100W. The datasheet recommends a 24V supply rated above 10A with no overshoot. Our AHVAPS24V power supply (24V, 21A) meets this, or you can order the amplifier "with 24V power".
Bandwidth drops as load capacitance rises: 15kHz at 100pF, 10kHz at 250pF, 8kHz at 500pF and 3kHz at 1nF. If you need more bandwidth, we can build a custom version with a larger heat sink.
Turn the bias knob. It adds −10V to +10V to the input signal. The sum (INBS, pin 7) is clipped to ±10V, which maps to the full ±1800V output.
Connect an oscilloscope to the Output Monitor BNC. −10V to +10V on this BNC means ±1800V at the output. The LPGD pin and the Loop Good LED show that the control loop works correctly.
Yes. Drive the SBDN pin: below 0.4V is Off, 2.1V to 2.51V is Standby, and above 2.64V is On.
AHVAPN1800V20MABN replaces AHVAPN1800V20MA. It has a banana high voltage output. If your setup uses SHV cables, add the AHVAPNBN2SHV SHV to banana cable.
