Overview
The AD9760AR50RL is a 10-bit resolution digital-to-analog converter (DAC) from Analog Devices Inc., part of the TxDAC series. This high-performance, low-power CMOS DAC is designed for various high-speed applications. The AD9760-50 variant, which the AD9760AR50RL is based on, is specified for 50 MSPS operation, making it suitable for applications requiring lower performance compared to the standard AD9760 model. The device features a segmented current source architecture combined with a proprietary switching technique to enhance dynamic performance and reduce spurious components.
