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.
