GENERAL DESCRIPTION
The AD9144 is a quad, 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a maximum sample rate of 2.8 GSPS, permitting a multicarrier generation up to the Nyquist frequency. The DAC outputs are optimized to interface seamlessly with the ADRF6720 analog quadrature modulator (AQM) from Analog Devices, Inc. An optional 3-wire or 4-wire serial port interface (SPI) provides for programming/readback of many internal parameters. Full-scale output current can be programmed over a typical range of 13.9 mA to 27.0 mA. The AD9144 is available in an 88-lead LFCSP.
