Overview
The AD9760ARZRL, produced by Analog Devices Inc., is a high-performance, low-power CMOS digital-to-analog converter (DAC) with a 10-bit resolution. It is part of the TxDAC series, which is optimized for the transmit signal path of communication systems. This DAC offers exceptional AC and DC performance, supporting update rates up to 125 MSPS. The AD9760ARZRL is designed for flexibility, with a single-supply operating range of 2.7 V to 5.5 V, making it suitable for portable and low-power applications. It features a segmented current source architecture and a proprietary switching technique to enhance dynamic performance and reduce spurious components.
