The AD9704/AD9705/AD9706/AD9707 are the fourth-generation family in the TxDAC series of high performance, CMOS digital-to-analog converters (DACs). This pin-compatible, 8/10/12/14bit resolution family is optimized for low power operation, while maintaining excellent dynamic performance. The AD970x family is pin-compatible with the AD9748/AD9740/ AD9742/AD9744 family of TxDAC converters and is specifically optimized for the transmit signal path of communication systems. All of the devices share the same interface, LFCSP_VQ package, and pinout, providing an upward or downward component selection path based on performance, resolution, and cost. The AD970x offers exceptional ac and dc performance, while supporting update rates up to 175 MSPS.
The flexible power supply operating range of 1.7 V to 3.6 V and low power dissipation of the AD970x parts make them well-suited for portable and low power applications.
Power dissipation of the AD970x can be reduced to 15 mW, with a small trade-off in performance, by lowering the full-scale current output. In addition, a power-down mode reduces the standby power dissipation to approximately 2.2 mW.
The AD970x has an optional serial peripheral interface (SPI) that provides a higher level of programmability to enhance performance of the DAC. An adjustable output, common-mode feature allows for easy interfacing to other components that require common modes greater than 0 V.
Edge-triggered input latches and a 1.0 V temperature-compensated band gap reference have been integrated to provide a complete, monolithic DAC solution. The digital inputs support 1.8 V and 3.3 V CMOS logic families.
