• Levels TTL and CMOS compatible digital inputs
• 3 to 5 V CMOS digital outputs
• Low-level AC clock input signal allowed
• Internal reference voltage regulator
• Power dissipation only 235 mW (typical)
• Low analog input capacitance, no buffer amplifier
required
• No sample-and-hold circuit required.
APPLICATIONS
High-speed analog-to-digital conversion for:
• Video data digitizing
• Radar pulse analysis
• Transient signal analysis
• High energy physics research
• Σ∆ modulators
• Medical imaging.
GENERAL DESCRIPTION
The TDA8763 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-coded digital words at a maximum
sampling rate of 50 MHz. All digital inputs and outputs are
TTL and CMOS compatible, although a low-level sine
wave clock input signal is allowed.
The device includes an internal voltage reference
regulator. If the application requires that the reference is
driven via external sources the recommendation is to use
the TDA8763A.
