analog-to-digital converter
Product specification
TDA8762A
FEATURES
• 10-bit resolution
• Sampling rate up to 80 MHz
• DC sampling allowed
• One clock cycle conversion only
• High signal-to-noise ratio over a large analog input
frequency range (9.3 effective bits at 4.43 MHz
full-scale input at f_clk = 80 MHz)
• No missing codes guaranteed
• In range (IR) TTL output
• TTL compatible digital inputs and outputs
• Low-level AC clock input signal allowed
• External reference voltage regulator
• Power dissipation only 380 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 TDA8762A is a 10-bit high-speed 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
80 MHz. All digital inputs and outputs are TTL compatible,
although a low-level sine wave clock input signal is
allowed.
