The PCM186x family (PCM1860, PCM1861, PCM1862, PCM1863, PCM1864, and PCM1865) 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 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 audio front end supports single-ended input levels from small-mV microphone inputs to 2.1-VRMSline 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 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.
