ADVANCED DATASHEET SHEET D LND056-48 180V, 96 Channel MEMs Driver with DC/DC & Energy Savings Subsystem GENERAL DESCRIPTION FEATURES 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. Separate LND056-48 channels are dieletrically isolated to minimize crosstalk. The LND056-48 is packaged in a 6x6mm, 169 bump, 0.4mm pitch BGA package.
