描述 Description

GENERAL DESCRIPTION
The TDA8764 is a 10-bit high-speed low-power Analog-to-Digital Converter (ADC) for professional video and other applications. It converts the analog input signal into 10-bit binary or gray coded digital words at a maximum sampling rate of 40 MHz (/4 version) and 80 MHz (/8 version). All digital inputs and outputs are TTL
compatible, although a low-level sine wave clock input signal is allowedFEATURES
• 10-bit resolution (binary or gray code)
• Sampling rate up to 40 MHz (/4 version)
   Sampling rate up to 80 MHz (/8 version)
• DC sampling allowed
• One clock cycle conversion only
• High signal-to-noise ratio over a large analog input frequency range (9.5 effective bits at 5 MHz; full-scale input at fclk = 40 MHz)
• No missing codes guaranteed
• In-Range (IR) CMOS output
• TTL and CMOS levels compatible digital inputs
• 2.7 to 3.6 V CMOS digital outputs
• Low-level AC clock input signal allowed
• Internal reference voltage regulator
• Power dissipation only 250 mW (typical for /4 version)
   Power dissipation only 375 mW (typical for /8 version)
• Low analog input capacitance, no buffer amplifier required
• No sample-and-hold circuit requiredAPPLICATIONS
High-speed analog-to-digital conversion for:
• Video data digitizing
• Radar pulse analysis
• Transient signal analysis
• High energy physics research
• Σ∆ modulators
• Medical imaging.
