WMA-100 DC - 500kHz HV amplifier
!
Compact all-round high voltage amplifier
● -175V to +175V Output voltage
● DC to 500kHz @ -3dB large signal
bandwidth
● Low output noise: 350µVrms in DC 1MHz
● Current: 100mA with current limit
● Stable with all capacitive loads,
generates no overshoot
● DC offset control knob
The WMA-100 is a compact all-round, general-purpose
high voltage linear amplifier. It offers a wide output
voltage range (±175V), DC offset control, and
impressive bandwidth (DC - 500kHz) and noise (350
µVrms) specifications. The amplifier generates no
overshoot with any capacitive load. The short-circuit
protection with a fast current limit make this amplifier
suitable for both normal daily laboratory use and
automated measurement systems.
Typical applications include the use of the WMA-100
amplifier as a high speed, low noise piezo driver, an
amplifier for actuating MEMS devices, or for steering EOmodulators. It can also be used as a stand-alone low
noise high voltage power supply.
Combined with its modest price and small form factor, it is
the ideal choice for many experiments that require a high
quality and reliable high voltage amplifier.
