Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LMV1024/LMV1026 PDM Output with Pre-Amplifier for Electret Microphones November 2005 LMV1024/LMV1026 (Stereo) PDM Output with Pre-Amplifier for Electret.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

National’s LMV1024 and LMV1026 stereo amplifiers are solutions for the new generation of voice enrichment capabilities.

National has integrated sigma delta modulation and analog cores to improve the voice quality and the performance and to support designer’s choices.

Each 20 kHz preamplifier drives a Pulse Density Modulated (PDM) signal at an over sampled 60 bit stream, offering ..
