TDA8760
APPLICATIONS
• High-speed analog-to-digital conversion for
– Video signal digitizing
– High Definition TV (HDTV)
– Digital video broadcasting (satellite and cable)
– Transient signal analysis
– High energy physics research
– Sigma-delta (SD) modulators
– Medical imaging
– Radar pulse digitizing.
GENERAL DESCRIPTION
The TDA8760 is a monolithic bipolar 10-bit
Analog-to-Digital Converter (ADC) for video or other
applications. It converts the analog input signal into 10-bit
binary coded digital words at a maximum sampling rate of
40 MHz. All digital inputs and outputs are TTL compatible.
However, a sine wave clock input signal is allowed.
