The AD9152 is a dual, 16-bit, high dynamic range digital-to analog converter (DAC) that provides a maximum sample rate of 2.25 GSPS, permitting a multicarrier generation up to the Nyquist frequency. The DAC outputs are optimized to interface seamlessly with the ADRF6720 analog quadrature modulators (AQMs) from Analog Devices, Inc. An optional 3-wire or 4-wire serial port interface (SPI) provides for programming/readback of many internal parameters. Full-scale output current can be programmed over a range of 4 mA to 20 mA. The AD9152 is available in an 56-lead LFCSP. The AD9152 is a member of the TxDAC+® family.
