Product Summary

The TP3054N is an enhanced serial interface CODEC/Filter COMBO. The TP3054N consists of m-law monolithic PCM CODEC/filter utilizing the A/D and D/A conversion architecture, and a serial PCM interface. The TP3054N is fabricated using National’s 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. Also included are auto-zero circuitry and a companding coder which samples the filtered signal and encodes it in the companded μ-law format.

Parametrics

TP3054N absolute maximum ratings: (1)VCC to GNDA: 7V; (2)VBB to GNDA: -7V; (3)Voltage at any Analog Input or Output: VCC -0.3V to VBB +0.3V; (4)Voltage at any Digital Input or Output VCC -0.3V to GNDA +0.3V; (5)Operating Temperature Range: -25℃ to +125℃; (6)Storage Temperature Range: -65℃ to +150℃; (7)Lead Temperature (Soldering, 10 seconds): 300℃; (8)ESD (Human Body Model), Latch-Up Immunity = 100 mA on any Pin: 2000V.
