AD9726BSVZ

AD9726 is a 16bit digital-to-analogue converter (DAC) that offers leading edge performance at conversion rates of up to 400 MSPS. The device uses low voltage differential signalling (LVDS) inputs and includes internal 100 ohm terminations. The analogue output can be single-ended or differential current. An internal precision reference is included. The AD9726 also features synchronization logic to monitor and optimize the timing between incoming data and the sample clock. This reduces system complexity and simplifies timing requirements. An LVDS clock output is also available to drive an external data pump in either single data rate (SDR) or double data rate (DDR) mode. 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. Application includes instrumentation, test equipment, waveform synthesis, communications systems.
