Combined multiplexer and digital / analog converter (DAC) RDA012M4MS
Rockwell Scientific
The RDA012M4MS is a 48:12 bit multiplexer and digital to analog converter (DAC) with an update rate over 1GS/s. The MUXDAC features master-slave operation that simplifies synchronization when multiple MUXDACs are required, such as in an I-Q modulation scheme. The integrated DAC utilizes a segmented current source to reduce the glitch energy and to achieve high linearity performance. For best dynamic performance, the DAC outputs are internally terminated with 50Ω resistance, and outputs a nominal full scale current of 12mA when terminated with external 50Ω resistors. For a convenient interface with most CMOS ICs, the digital data inputs are low voltage NMOS compatible.
