3 Description
The PCM186x-Q1 family (PCM1860-Q1, PCM1861-
Q1, PCM1862-Q1, PCM1863-Q1, PCM1864-Q1, and
PCM1865-Q1) of audio front-end devices take a new
approach to audio-function integration to ease
compliance with European Ecodesign legislation,
while enabling high-performance end products at
reduced cost. The PCM186x-Q1 support single-
supply 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 single-
ended input levels from small-mV microphone inputs
to 2.1-VRMS line inputs, without external resistor
dividers. The front-end mixer (MIX), multiplexer
(MUX), and PGA also support differential (Diff),
pseudo-differential, and single-ended (SE) inputs,
making these devices an ideal interface for products
that require interference suppression. The PCM186x-
Q1 integrate many system-level functions that assist
or replace some DSP functions.
An integrated band-gap voltage reference provides
excellent PSRR, so that a dedicated analog 3.3-V rail
may not be required.
