AD9726 16-Bit, 400 MSPS TxDAC+® D/A Converter
Product Details
The AD9726 is a 16-bit high performance LVDS DAC that offers exceptional noise and spurious performance and true 16-bit dc linearity. Manufactured on a CMOS process, the AD9726 uses a proprietary switching technique that enhances dynamic performance. A wide full-scale current adjustment span of 2 mA to 20 mA allows the AD9726 to operate at reduced power levels. The current output(s) of the AD9726 can be easily configured for various single-ended or differential circuit topologies.
The AD9726 leverages the latest TxDAC+ core technology found in the AD9786 product family to achieve industry-leading noise and intermodulation distortion (IMD) performance. This record-breaking performance allows synthesis of multicarrier transmit signals at intermediate frequencies (IFs) of 140 MHz and beyond. As a result, system designers can eliminate an up-conversion stage and reduce overall parts count, ultimately lowering total system cost. Alternatively, the high conversion rate enables wideband signal synthesis.
