GENERAL DESCRIPTION

The AD9714/AD9715/AD9716/AD9717 are pin-compatible dual, 8-/10-/12-/14-bit, low power digital-to-analog converters (DACs) that provide a sample rate of 125 MSPS. These TxDAC® converters are optimized for the transmit signal path of communication systems. All the devices share the same interface, LFCSP package, and pinout, providing an upward or downward component selection path based on performance, resolution, and cost. The AD9714/AD9715/AD9716/AD9717 offer exceptional ac and dc performance and support update rates up to 125 MSPS. The flexible power supply operating range of 1.8 V to 3.3 V and low power dissipation of the AD9714/AD9715/AD9716/AD9717 make them well-suited for portable and low power applications.
