The AD9707 is a14-bit resolution, low power, fourth generation member of the TxDAC series of high performance, CMOS digital-to-analog converters (DACs). The AD970x family, consisting of 8-, 10-, 12-, and 14-bit DACs, is pin compatible with the AD974x family of TxDACs and is specifically optimized for the transmit signal path of communication systems. All of the devices share the same interface, small outline package, and pinout, providing an upward or downward component selection path based on performance, resolution, and cost. The AD9707 offers exceptional ac and dc performance while supporting update rates up to 175 MSPS.
The AD9707's flexible power supply operating range of 1.7 V to 3.6 V and low power dissipation makes it well suited for portable and low power applications. Its power dissipation can be further reduced to 15 mW with a slight degradation in performance by lowering the full-scale current output. Also, a power-down mode reduces the standby power dissipation to approximately 5 mW.
The AD9707-LFCSP has an optional serial peripheral interface (SPI) which provides a higher level of programmability to enhance performance of the DAC. An adjustable output common mode feature has also been added to the AD9707-LFCSP that 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.
