描述 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.
