Product Summary

The AD9760ARZRL is a 10-bit resolution member of the TxDAC series of high performance, low power CMOS digital-to-analog converter (DAC). The AD9760ARZRL is a lower performance option that is guaranteed and specified for 50 MSPS operation. The TxDACfamily that consists of pin compatible 8-, 10-, 12- and 14-bit DACs is specifically optimized for the transmit signal path of communication systems. All of the devices share the same interface options, small outline package and pinout, thus providing an upward or downward component selection path based on performance, resolution and cost. The AD9760ARZRL offers exceptional ac and dc performance while supporting update rates up to 125 MSPS and 60 MSPS respectively. The AD9760ARZRL 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 mW 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 mW. The AD9760ARZRL is manufactured on an advanced CMOS process. A segmented current source architecture is combined with a proprietary switching technique to reduce spurious components and enhance dynamic performance. Edge-triggered input latches and a 1.2 V temperature compensated bandgap reference have been integrated to provide a complete monolithic DAC solution. Flexible supply options support +3 V and +5 V CMOS logic families. The AD9760ARZRL is available in a 28-lead SOIC and TSSOP packages. It is specified for operation over the industrial temperature range. The AD9760ARZRL can be applied in communication transmit channel, direct digital synthesis (dds),and instrumentation.
