AD9752:  12-Bit, 100 MSPS+ TxDAC® D/A Converter

Product Description

The AD9752 is a 12-bit resolution second generation member of the TxDAC series of high performance, low power CMOS digital-to-analog converters (DACs). The TxDAC family, which consists of pin compatible 8-, 10-, 12-, and 14-bit DACs, is speci-fically 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 AD9752 offers exceptional ac and dc performance while supporting update rates up to 125 MSPS.
