The AD9154 is a quad, 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a maximum sample rate of 2.4 GSPS, permitting multicarrier generation up to the Nyquist frequency in baseband mode. The AD9154 includes features optimized for direct conversion transmit applications including complex digital modulation, input signal power detection, and gain, phase, and offset compensation. The DAC outputs are optimized to interface seamlessly with the ADRF672x radio frequency quadrature modulators from Analog Devices, Inc. In mix mode, the AD9154 DAC can reconstruct carriers in the 2nd and 3rd Nyquist Zones. A serial port interface (SPI) provides for the programming/readback of internal parameters. The full-scale output current can be programmed over a range of ?4 mA to ?20 mA. The AD9154 is available in an 88-lead LFCSP.
