Overview
The AD9750ARURL7 is a 10-bit resolution, wideband, high-performance digital-to-analog converter (DAC) from Analog Devices Inc. It is part of the TxDAC series, optimized for the transmit signal path of communication systems. This DAC offers exceptional AC and DC performance, supporting update rates up to 125 MSPS. It is designed for low power applications, with a flexible single-supply operating range of 4.5 V to 5.5 V and low power dissipation that can be further reduced to 65 mW by adjusting the full-scale current output. The device also features a power-down mode to minimize standby power consumption.
