Overview
The AD9154BCPAZRL is a quad, 16-bit, high dynamic range digital-to-analog converter (DAC) produced by Analog Devices Inc. This component is part of the AD9154 series and 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 DAC outputs are tailored to interface seamlessly with the ADRF6720-27 radio frequency quadrature modulator (AQM) from Analog Devices.
