12-bit, 70 Msps Analog-to-Digital Converter (ADC) Rev. 02 - 03 July 2002 Product data 1. Description The TDA8768AH is a bi CMOS 12-bit Analog-to-Digital Converter (ADC) optimized for GSM and EDGE cellular infrastructures, professional telemunications and imaging, and advanced FM radio. It converts the analog input signal into 12-bit binary coded digital words at a maximum sampling rate of 70 MHz. All static digital inputs (SH, CE and OTC) are TTL and CMOS patible and all outputs are CMOS patible. A sine wave clock input signal can also be used. 2.
