1. Description
The TDA8768AH is a bi
CMOS 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.
2. Features
s 12-bit resolution s Sampling rate up to 70 MHz s −3 dB bandwidth of 245 MHz s 5 V power supplies and 3.3 V output power supply s Binary or twos complement
