A new approach to audio-function integration to ease compliance with
European Ecodesign legislation while enabling high-performance end products
- Texas Instruments' (TI) has introduced the PCM186x family of audio
front-end devices. With no need for a 5V supply or an external
programmable-gain amplifier, smaller, smarter products are now 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.
All these features are available using a single 3.3V power supply. An
integrated bandgap voltage reference provides exceptional PSRR, so that a
dedicated analog 3.3V rail may not be required, says the company.
