Product Summary

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.
