LMV1024/LMV1026 PDM Output with Pre-Amplifier for Electret Microphones November 2005 LMV1024/LMV1026 (Stereo) PDM Output with Pre-Amplifier for Electret Microphones 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 www.DataSheet4U.com versatility. These solutions provide immediate conversion to high performance audio spectrum, thus completing a high quality audio system. The LMV1024 and LMV1026 operate from 1.6V to 3V.
