AVPRO-5001

Quad A/V driver

TDK Corporation 

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.
