WMA-280 Low noise high precision high voltage amplifier

The WMA-280 is a high voltage, low noise precision amplifier. Its specifications have been designed to serve the needs of a wide variety of high-tech experiments. The WMA-280 can be used for MEMS actuation, EO-modulators, as high voltage driver for PZT (piezo) positioners, ultrasonics, and many other applications. Its output noise is only 300 microVolt rms.

Specifications:
- High voltage 20.0x amplification up to +150V and -150V with respect to ground
- DC to 100kHz full-power bandwidth (-3dB) and 300mA output current
- Low output noise: 300 microVolt rms
- High precision: <0.1% amplification error
- Continuous short-circuit protection
