Description

The AD9762 is the 12-bit resolution member of the TxDAC series of high performance, low power CMOS digital-to-analog converters (DACs). The TxDACfamily which consists of pin compatible 8-, 10-, 12-, and 14-bit DACs is specifically optimized for the transmit signal path of communication systems. All of the devices share the same interface options, small outline package and pinout, thus providing an upward or downward component selection path based on performance, resolution and cost. The device offers exceptional ac and dc performance while supporting update rates up to 125 MSPS.
