AD9726BSVZRL

Digital To Analog Converters Overview

The AD9726 is a 16-bit digital-to-analog converter (DAC) from Analog Devices Inc., operating at update rates up to 400 MSPS. It features low voltage differential signaling (LVDS) inputs with internal 100 Ω terminations and provides differential current outputs. The device includes an internal precision reference, automatic data/clock timing synchronization logic, and supports both single data rate (SDR) and double data rate (DDR) modes. Key performance metrics include SFDR ≥ 78 dBc at fOUT = 20 MHz, IMD ≥ 82 dBc at fOUT = 70 MHz, and DNL ≤ ±0.5 LSB. It operates on 2.5 V and 3.3 V supplies within an extended industrial temperature range of −40°C to +85°C.
