Product Summary

The AD9742ARZ is a 12-bit resolution, wideband, third generation member of the TxDAC series of high-performance, low power CMOS digital-to-analog converters (DACs). The AD9742ARZ, consisting 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, providing an upward or down-ward component selection path based on performance, resolution, and cost. The AD9742ARZ offers exceptional ac and dc performance while supporting update rates up to 165 MSPS. The applications of the AD9742ARZ are Wideband Communication Transmit Channel: (1)Direct IF; (2)Base Stations; (3)Wireless Local Loop; (4)Digital Radio Link; (5)Direct Digital Synthesis (DDS); (6)Instrumentation.
