The TDA8763AM and the TDA8763M are 10-bit Analog-to-Digital Converters. They can convert a typical analog input signal into 10 bits binary coded digital words at a maximum sampling rate of 50 Mega sample per second with a typical power dissipation of 175mW for the  TDA8763AMand 235mW for the TDA8763M.

The TDA8763AMand theTDA8763Mcode either binary or two’s complement digital words with 3V to 5V25 CMOS digital outputs. The  TDA8763Mcontains an internal reference voltage regulator ensuring the TOP and the BOTTOM reference voltages of the  quantization ladder.
