ADVANCED DATASHEET LND056-48 200V, 96 Channel MEMs Driver with DC/DC & Energy Savings Subsystem GENERAL DESCRIPTION The LND056-48 is a complete high voltage driver subsystem capable of driving up to 96 muxed output channels from 48 inputs. Each channel is a high precision, uV offset, nulled opamp with a fixed 50V/V gain capable of achieving 0.03% output accuracy. The LND056-48 also includes all circuitry required to generate three high-voltage rails using a small number of external components. A patents pending high power subsystem makes the LND056-48 the lowest power solution for driving high voltage MEMs, drawing only 47mW of power in a typical application. Each of the channels on the LND056-48 are dieletrically isolated to minimize crosstalk. The LND056-48 is packaged in a 5x5mm 169 channel BGA package.
