TDA8772H/8数据手册恩XP中文资料规格书

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
• 75Ωoutput 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
