• 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.
APPLICATIONS
• General purpose high-speed analog-to-digital
conversion
• Digital TV, IDTV
• Subscriber TV decoder
• Satellite TV decoders
• Digital VCR.
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.
