GENERAL DESCRIPTION

The TDA8716 is an 8-bit high-speed Analog-to-Digital
Converter (ADC) designed for HDTV and professional
applications. The device converts the analog input signal
into 8-bit binary coded digital words at a sampling rate of
120 MHz. All digital outputs are ECL compatible.

HANDLING

Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling integrated circuits.
