GENERAL DESCRIPTION The AD9726 is a 16-bit digital-to-analog converter (DAC) that offers leading edge performance at conversion rates 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. The AD9726 also features synchronization logic to monitor and optimizes the timing between incoming data and the sample clock. This reduces system complexity and simplifies timing require- ments. 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. PRODUCT HIGHLIGHTS 1. A unique combination of precision and performance makes the AD9726 equally suited to applications with demanding frequency domain or demanding time domain requirements. 2. Nonvolatile factory calibration assures a highly linear transfer function. Internal logic offers on demand self- calibration for linearity even at extended operating temperatures. 3. Proprietary architecture minimizes data dependent, discrete mixing spurs and offers enhanced dynamic performance over a wide range of output frequencies. High input data rates create a very high frequency synthesis bandwidth. 4. The fully automatic, transparent synchronizer maintains optimized timing between clock and data in real time and offers programmable control options for added flexibility. 5. Full-scale output current is external resistor programmable. |
