GENERAL DESCRIPTION
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 ADRF6720-27 radio
frequency quadrature modulator (AQM) from Analog Devices,
Inc. In mix mode, the AD9154 DAC can reconstruct carriers in
the second and third Nyquist zones. A serial port interface (SPI)
provides the programming/readback of internal parameters.
The full-scale output current can be programmed over a range
