The DAC outputs are optimized to interface seamlessly with the ADRF6720 analog quadrature modulator (AQM) from Analog Devices, Inc. An optional 3-wire or 4-wire serial port interface (SPI) provides for programming/readback of many internal parameters. The full-scale output current can be programmed over a range of 4 m A to 20 m A. The AD9152 is available in a 56-lead LFCSP. The AD9152 is a member of the Tx DAC+® family. PRODUCT HIGHLIGHTS 1. Ultrawide signal bandwidth enables emerging wideband and multiband wireless applications. 2. Advanced low spurious and distortion design techniques provide high quality...
