LMV1026 Datasheet Pdm Output With Pre-amplifier

Manufacturer: Texas Instruments

Overview: OBSOLETE LMV1024, LMV1026 .ti. SNAS295B – MARCH 2005 – REVISED JULY 2009 LMV1024/LMV1026 (Stereo) PDM Output with Pre-Amplifier for Electret Microphones Check for Samples: LMV1024,.

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 versatility.
