Codec Telecom 1-CH 16Bit 3.3V 24-Pin SSOP Rail

The PCM3500 is a low cost, 16-bit CODEC designed for modem Analog Front End (AFE) and speech processing applications. The PCM3500’s low power operation from +2.7V to +3.6V power supplies, along with an integrated power-down mode, make it ideal for portable applications. The PCM3500 integrates all of the functions needed for a modem or voice CODEC, including delta-sigma digital-to-analog and analog-to-digital converters, input anti-aliasing filter, digital high-pass filter for DC blocking, and an output low-pass filter. The synchronous serial interface provides for a simple, or glue-free interface to popular DSP and RISC processors. The serial interface also supports Time Division Multiplexing (TDM), allowing up to four CODECs to share a single 4-wire serial bus.
