Texas Instruments' PCM186x family of audio front-end devices takes a new approach to audio-function integration to ease compliance with European Ecodesign legislation while enabling high-performance end products. With no need for a 5 V supply or an external programmable-gain amplifier, smaller, smarter products are feasible at reduced cost.

The PCM186x’s highly flexible audio front-end supports input levels from small-mV microphone inputs to 2.1 VRMS line inputs without external resistor dividers. The PCM186x family integrates many system-level functions that assist or replace some DSP functions.
