ML7048-01
3-Channel Single Rail CODEC
This version: Oct. 2001
Preliminary
GENERAL DESCRIPTION
The ML7048 is a three-channel single rail CMOS CODEC LSI. This device contains filters for A-to-D and D-to-
A conversions of voice signals ranging 300 to 3400 Hz.
The ML7048 is designed for a single power supply and low power applications and contains three-channel A-to-
D and D-to-A converters on a single chip, and achieves a reduced footprint and external component parts.
The ML7048 is best suited for ISDN terminal and digital telephone terminal applications.
