Product data
1. Description
The TDA8768AH is a biCMOS 12-bit Analog-to-Digital Converter (ADC) optimized for
GSM and EDGE cellular infrastructures, professional telecommunications 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 compatible and all outputs are CMOS
compatible. A sine wave clock input signal can also be used.
