Analog Devices Inc. AD9144 16-Bit Quad DAC

Analog Devices Inc. AD9144 Quad DAC is a 16-Bit high dynamic range digital-to-analog converter (DAC) that offers a maximum sample rate of 2.8GSPS, which supports a multicarrier generation up to the Nyquist frequency. The DAC outputs are optimized to interface seamlessly with the ADRF672x analog quadrature modulators (AQMs). 

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 13.9mA to 27.0mA. Available in an 88-lead LFCSP package, AD9144 is ideal for wireless communications, wideband communications, transmit diversity, multiple input / multiple output (MIMO), instrumentation, and automated test equipment.
