The Model 2375 is a four-channel amplifier claimed to offer the ultimate in precision amplification for MEMS comb drives, cantilevered beams and other electrostatic actuators.

Available now from Tegam, the Model 2375 is a four-channel amplifier claimed to offer the ultimate in precision amplification for MEMS comb drives, cantilevered beams and other electrostatic actuators.

It is also ideal for use in applications requiring precise amplification of unipolar or DC biased AC waveforms.

Each of the 2375's four channels is rated for 20mA continuous current with 0.2ohm output impedance.

The amplifier can drive capacitive loads up to 200pF while maintaining a full-power bandwidth exceeding 5kHz.

Each channel has an independent voltage monitor output for use in a closed loop system.

The buffers produce a reduction of 100:1 of the output voltage for measurement devices with a 1Mohm or higher output impedance.

The 2375 was designed specifically for use with the Tegam Model 9070 MEMS engine driver system, which was codeveloped with Sandia National Laboratories.

US pricing for the 2375 starts at $6495.

"This is another step in the aggressive expansion of Tegam's line of single and multiple channel waveform amplifiers", notes Terry Gambill, President of Tegam.
