DATA SHEET D 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).
