Overview
The AD9750ARUZRL7 is a 10-bit resolution, wideband digital-to-analog converter (DAC) from Analog Devices Inc., part of the TxDAC series. This device is optimized for the transmit signal path of communication systems and offers exceptional AC and DC performance. It supports update rates up to 125 MSPS, making it suitable for high-speed applications. The AD9750 features a flexible single-supply operating range of 4.5 V to 5.5 V and low power dissipation, which can be further reduced to 65 mW by lowering the full-scale current output. A power-down mode also reduces the standby power dissipation to approximately 20 mW.
