Overview
The AD9760ARU50RL is a 10-bit, high-performance, low-power CMOS digital-to-analog converter (DAC) from Analog Devices Inc. It is part of the TxDAC series and is known for its excellent spurious free dynamic range (SFDR) performance. The AD9760 and its variant, AD9760-50, are designed for applications requiring high dynamic performance and low power consumption. The AD9760-50 is specifically optimized for 50 MSPS operation, while the AD9760 can operate up to 125 MSPS. These DACs feature a segmented current source architecture combined with a proprietary switching technique to enhance dynamic performance and reduce spurious components.
