RDA012M4MS

The RDA012M4MS is a digital-to-analog converter (DAC) with a 4:1 input multiplexer and a maximum update rate of 1.3GS/s. The RDA012M4MS features master-slave operation that simplifies synchronization when multiple devices are required, such as in an I-Q modulation scheme. The integrated DAC utilizes a segmented current source to reduce the glitchenergy and achieve high linearity performance. For best dynamic performance, the DAC outputs ofRDA012M4MS are internally terminated with 50 resistance, and outputs a nominal full-scale current of 12mA when terminated with external 50 resistors. For a convenient interface with most CMOS ICs, the digital data inputs are low voltage NMOS compatible.
