Overview
The AD9154BCPAZ is a quad, 16-bit, high dynamic range digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is designed to provide a maximum sample rate of 2.4 GSPS, enabling multicarrier generation up to the Nyquist frequency in baseband mode. It is optimized for direct conversion transmit applications, including complex digital modulation, input signal power detection, and gain, phase, and offset compensation. The AD9154 is particularly suited for interfacing with the ADRF6720-27 radio frequency quadrature modulator (AQM) from Analog Devices, Inc.
