ML7019
SINGLE RAIL DUAL CHANNEL CODEC
v
General Description
The ML7019 is a two-channel single-rail CODEC CMOS IC for voice signals
ranging from 300 to 3400Hz.This device contains two-channel analog-to-digital
(A/D) and digital-to-analog (D/A) converters on a single chip. The ML7019 is
designed especially for a single power supply and low power applications and
achieves a reduced footprint.
The ML7019 is best suited for line card applications with easy interface to
subscriber line interface circuits (SLICs). The SLIC interface latches are embedded
onto this CODEC, thus eliminating the need for external components and
optimizing board space.
