TCM129C18 - PCM codecs

Download the TCM129C18 datasheet PDF. This datasheet also covers the TCM29C18 variant, as both devices belong to the same pcm codecs family and are provided as variant models within a single manufacturer datasheet.

General Description

The TCM29C18, TCM29C19, TCM129C18, and TCM129C19 are low-cost single-chip PCM codecs (pulse-code-modulated encoders and decoders) and PCM line filters.

These devices incorporate both the A/D and D/A functions, an antialiasing filter (A/D), and a smoothing filter (D/A).
