FSADJ Figure 1 GENERAL DESCRIPTION PRODUCT HIGHLIGHTS 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 О© terminations. The
analog output can be single-ended or differential current. An
internal precision reference is included. 1. All device operation is fully programmable using the flexible
serial port interface (SPI). The AD9726 is also fully functional
in its default state for applications without a controller. 16-BIT
