Summary: TP3054N, Interface CODEC/Filter COMBO, 16-DIP, 7V, 9mA, National Semiconductor
Description: 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.
