Product Summary

The TP3057WM is an enhanced serial interface CODEC. It consists of m-law and A-law monolithic PCM CODEC/filters utilizing the A/D and D/A conversion architecture shown inFigure 1 , and a serial PCM interface. The TP3057WM is fabricated using Nationals advanced double-poly CMOS process (microCMOS). The encode portion of each device consists of an input gain adjust amplifier, an active RC pre-filter which eliminates very high frequency noise prior to entering a switched-capacitor band-pass filter that rejects signals below 200 Hz and above 3400 Hz.

Parametrics

TP3057WM absolute maximum ratings: (1)VCC to GNDA: 7V; (2)VBB to GNDA: 7V; (3)Operating temperature range: 25 to 125℃; (4)lead temperature: 300℃; (5)storage temperature: 300℃.

Features

TP3057WM features: (1)Complete CODEC and filtering system (COMBO); (2)Transmit high-pass and low-pass filtering; (3)Receive low-pass filter with sin x/x correction; (4)Active RC noise filters; (5)m-law or A-law compatible COder and DECoder; (6)Internal precision voltage reference; (7)Serial I/O interface; (8)Internal auto-zero circuitry; (9)m-law, 16-pinDTP3054.
