描述 Description

GENERAL DESCRIPTION
The TDA8772 is a triple 8-bit video Digital-to-Analog Converter (DAC). It converts the digital input signals into
analog voltage outputs at a maximum conversion rate of 35 MHz (TDA8772H/3) and 85 MHz (TDA8772H/8).FEATURES
? 8-bit resolution
? Sampling rate up to:
? – 35 MHz for TDA8772H/3
? – 85 MHz for TDA8772H/8
? Internal reference voltage regulator
? No deglitching circuit required
? SYNC,BLANK control inputs
? 3 independent clock inputs (one per DAC)
? 1 V output voltage range
? 75?output load
? TDA8772 hasBLANK control on the 3 channels
? Single 5 V power supply
? 44-pin QFP package.

APPLICATIONS
? General purpose high-speed digital-to-analog conversion
? Digital TV
? Graphic display
? Desktop video processing.
