Overview
The AD9726BSVZRL is a 16-bit digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is renowned for its high-performance capabilities, particularly in applications requiring precise and rapid conversion rates. The AD9726 operates at conversion rates of up to 400 MSPS, making it suitable for demanding frequency and time domain applications. It features low voltage differential signaling (LVDS) inputs, internal 100 Ω terminations, and the ability to output single-ended or differential current. An internal precision reference and synchronization logic enhance its performance and simplify system timing requirements.
