Datasheet Summary
BL1302A57/S
General Description
The BL1302A57/S is an A-law monolithic PCM Pin Assignment
CODEC/filter which has the A/D and D/A conversion and a serial PCM interface. The device is fabricated using the advanced double-poly nwell CMOS process. It is pin patible with TP3057. 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
