GENERAL DESCRIPTION
The TDA8703 is an 8-bit high-speed Analog-to-Digital Converter (ADC) for video and other applications. It converts the analog input signal into 8-bit binary-coded digital words at a maximum sampling rate of 40 MHz. All digital inputs and outputs are TTL compatible, although
a low-level AC clock input signal is allowed.
FEATURES
• 8-bit resolution
• Sampling rate up to 40 MHz
• High signal-to-noise ratio over a large analog input frequency range (7.1 effective bits at 4.43 MHz full-scale input)
• Binary or two's complement 3-state TTL outputs
• Overflow/underflow 3-state TTL output
• TTL compatible digital inputs
• Low-level AC clock input signal allowed
• Internal reference voltage generator
• Power dissipation only 290 mW (typical)
• Low analog input capacitance, no buffer amplifier required
• No sample-and-hold circuit required.
