3 Description
The PCM186x-Q1 family (PCM1860-Q1, PCM1861Q1, PCM1862-Q1, PCM1863-Q1, PCM1864-Q1, and PCM1865-Q1) of audio front-end devices take a new approach to audio-function integration to ease pliance with European Ecodesign legislation, while enabling high-performance end products at reduced cost. The PCM186x-Q1 support singlesupply operation at 3.3 V, and offer an integrated programable gain amplifier (PGA) in a small package; this configuration makes it feasible to implement smaller and smarter products at a reduced cost.
The PCM186x-Q1 audio front end supports singleended input levels from small-m V microphone inputs to 2.1-VRMS line inputs, without external resistor dividers. The front-end mixer (MIX), multiplexer (MUX), and PGA...
