Overview

LMV1022/LMV1023 PDM Output Preamp for Electret Microphones LMV1022/LMV1023 OBSOLETE July 8, 2011 PDM Output Pre-Amplifier for Electret Microphones General Description The LMV1022 and LMV1023 integrate a pre-amplifier and ADC that can be mounted inside an electret condenser microphone (ECM).
The digital output signal is a pulse density modulation (PDM) bitstream that alows the microphone to connect directly to the DSP or baseband processor.
Part of National Semiconductor’s Powerwise™ family of products, the LMV1022/LMV1023 consume 900µW of power during operation, offering significant power savings over an analog microphone with an external ADC.
The LMV1022 outputs its data on the rising c...
