Quad A/V Drivers

DESCRIPTION
The AVPro 5001 device is an audio/video driver IC
that supports four video inputs and two audio inputs.
Each video paths has a gain of 2 with output buffers
designed to drive a 137 ohm load. Each audio path
has two output drivers that are buffered to provide 2
Vrms output (3.2 Vrms maximum). In addition, the
audio drivers use +/- 5 volt power supplies so that
the output is centered around ground. This allows
direct coupling of the 5001 audio outputs to the
associated load. Typical applications for the 5001
include DVD players, VCRs, and digital receivers for
satellite, cable, and terrestrial television.
