LND-MA32
32 Channel High Voltage Amplifier
(Call Factory for Fewer Channels)
GENERAL DESCRIPTION
The MA32 is a precision 32 channel high voltage
driver for capacitive loads such as micro
electromechanical systems (MEMS). The gain of
each high voltage driver is internally set for 50
V/V. This allows selection of a 0 to 5V DAC for
driving each channel linearly from 0 to
approximately 250V. The internal gain setting
resistors have a total series resistance >= 2MΩ to
minimize static power dissipation when outputs
are at high voltage.
The MA32 is packaged in a 240 pin quad-flat
pack (QFP).
