TDA8768B
12-bit, 80 Msps Analog-to-Digital Converter (ADC)
Rev. 02 — 20 January 2004
Product data
1.
Description
The TDA8768B is a biCMOS 12-bit Analog-to-Digital Converter (ADC) optimized for
EDGE and W-CDMA cellular infrastructures, professional telecommunications and
other applications such as advanced FM radio and professional imaging. Its main
innovation is the RF sampling, based on high-speed clock (up to 80 Msps) combined
with a high input frequency (up to 176 MHz). It converts the analog input signal into
12-bit binary coded digital words at a maximum sampling rate of 80 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.
