GENERAL DESCRIPTION
The TDA8768 is a bipolar 12-bit Analog-to-Digital
Converter (ADC) optimized for telecommunications and
professional imaging. It converts the analog input signal
into 12-bit binary coded digital words at a maximum
sampling rate of 55 MHz. All static digital inputs (SH, CE
and OTC) are TTL and CMOS compatible and all outputs
are CMOS compatible. A sine wave clock input signal can
also be used.
