Description
The ETC5057D is a monolithic PCM CODEC/filter in the Interface - CODECs product category. It utilizes the A/D and D/A conversion architecture and features a serial PCM interface. The device is fabricated using doublepoly CMOS process. The encode portion of the ETC5057D consists of an input gain adjust amplifier, an active RC pre-filter, a switched-capacitor band-pass filter, auto-zero circuitry, and a companding coder. It supports both A-law and µ-law PCM formats.
