2 / 20 page  1997 Mar 06 2 Philips Semiconductors Product specification Triple 8-bit video digital-to-analog converter TDA8772 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 Ω output load • TDA8772 has BLANK 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. 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). The DAC is based on resistor-string architecture with integrated output buffers. The output voltage range is determined by a built-in reference source. The device is fabricated in a 5 V CMOS process that ensures high functionality with low power dissipation. ORDERING INFORMATION TYPE NUMBER PACKAGE SAMPLING FREQUENCY NAME DESCRIPTION VERSION TDA8772H/3 QFP44 plastic quad flat package; 44 leads (lead length 1.3 mm); body 10 × 10 × 1.75 mm SOT307-2 35 MHz TDA8772H/8 85 MHz |
