The AD9760-50 is a lower performance option that is guaranteed and specified for 50 MSPS operation. The Tx DAC family that consists of pin patible 8-, 10-, 12- and 14-bit DACs is specifically optimized for the transmit signal path of munication systems. All of the devices share the same interface options, small outline package and pinout, thus providing an upward or downward ponent selection path based on performance, resolution and cost. Both the AD9760 and AD9760-50 offer exceptional ac and dc performance while supporting update rates up to 125 MSPS and 60 MSPS respectively. The AD9760’s flexible single-supply operating range of 2.7 V to 5.5 V and low power dissipation are well suited for portable and low power applications. Its power dissipation can be further reduced to a mere 45 m W without a significant degradation in performance by lowering the full-scale current output. Also, a power-down mode reduces the standby power dissipation to approximately 25 m W. The AD9760 is manufactured on an advanced CMOS process. A segmented current source architecture is bined with a proprietary switching technique to reduce spurious ponents and enhance dynamic performance. Edge-triggered input latches and a 1.2 V temperature pensated bandgap reference have been...
