LSP2908 8-Channel, High-Voltage Driver
Eight amplifier channels package Outputs from -298 +160 channel Programmable output current limit (100 Variable voltage gain external resistors
condition that |VHP VHN| Voltage gain external resistors. Each amplifier output ideal deflection control optical MEMS mirrors. Output current limit programmed external resistor. Additionally, careful attention paid minimizing offset drift over temperature. LSP2908 requires negative high-voltage power supply (VHN) positive low-voltage power supply (VLP). positive output voltage applications, positive high-voltage power supply (VHP) required. Corresponding eight channels eight inverting input pins, -INx corresponding eight output pins, OUTPUTx Figure internal functional block diagram. noninverting input eight amplifiers. amplifiers share same noninverting input. should connected GND. IBIAS will current limit ((100 20%) amplifiers connecting external resistor Rib. LSP2908 available leaded surfacemount 44-pin MQFP package.
