ADI AD9135BCPAZ

The AD9135/AD9136 are dual, 11-/16-bit, high dynamic range digital-to-analog converters (DACs) that provide a maximum sample rate of 2800 MSPS, permitting a multicarrier generation over a very wide bandwidth. The DAC outputs are optimized to interface seamlessly with the ADRF6720, as well as other analog quadrature modulators (AQMs). An optional 3-wire or 4-wire serial port interface (SPI) provides for programming/readback of many internal parameters. The fullscale output current can be programmed over a typical range of 13.9 mA to 27.0 mA. The AD9135/AD9136 are available in an 88-lead LFCSP.
