GENERAL DESCRIPTION
The AD9726 is a 16-bit digital-to-analog converter (DAC) that offers leading edge performance at conversion rates of up to 400 MSPS. The device uses low voltage differential signaling (LVDS) inputs and includes internal 100 Ω terminations. The analog output can be single-ended or differential current. An internal precision reference is included.
