ADI AD9705BCPZ

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-/14-bit resolution family is optimized for low power operation, while maintaining excellent dynamic performance. The AD9704/AD9705/ AD9706/AD9707 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 package, and pinout, providing an upward or downward component selection path based on performance, resolution, and cost. The AD9704/AD9705/ AD9706/AD9707 offer 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 AD9704/AD9705/AD9706/AD9707 parts make them well suited for portable and low power applications. Power dissipation of the AD9704/AD9705/AD9706/AD9707 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 AD9704/AD9705/AD9706/AD9707 have 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 from 0 V to 1.2 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.
