LMV1022 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...
