Description
The
ML7033 is a 2-channel Line Card CODEC CMOS IC for voice signals ranging from 300
to 3400 Hz. This device contains 2-channel analog-to-digital (A/D) and
digital-to-analog (D/A) converters on a single chip. The ML7033 is designed
especially for a single power supply and low power applications and achieves a
reduced footprint. The ML7033 is best suited for line card applications with
easy interface to subscriber line interface circuits (SLICs). Especially
Intersil HC5518x series.
