10-bit, 500 Msps Digital-to-Analog
Converter (DAC)
Product specification
TDA8776
FEATURES
• 10-bit resolution
• Conversion rate up to 500 MHz
• 10K/100K ECL input levels
• Internal reference voltage generator
• No deglitching circuit required
• Internal input register
• Power dissipation only 925 mW (typical)
• Internal 50 Ω output load (connected to the analog
ground)
• Very few external components required.
APPLICATIONS
High-speed digital-to-analog conversion for:
• High resolution video and graphics
• Direct Digital Synthesis (DDS)
• Telecommunication
• High-speed modems.
GENERAL DESCRIPTION
The TDA8776 is a 10-bit Digital-to-Analog Converter
(DAC) for high resolution video and other high frequency
applications. It converts the digital input signal into an
analog output voltage at a maximum conversion rate of
500 Msps. No external reference voltage is required and
all digital inputs are 10K/100K-ECL compatible.

Notes
1. D0 to D9 connected to either HIGH or LOW level, CLK is HIGH and CLK is LOW.
2. The analog output voltages (VOUT and VOUT) are negative with respect to AGND (see Table 1). The external output
resistance between AGND and each of these outputs is typically 50 Ω.
3. A warm-up time is necessary to reach optimal performances.
