DAC5662A - Texas Instruments

DAC5662A DIGITAL-TO-ANALOG CONVERTER

The DAC5662A is a monolithic, dual-channel 12-bit high-speed digital-to-analog converter (DAC) with onchip voltage reference. Operating with update rates of up to 275 MSPS, the DAC5662A offers exceptional dynamic performance and tight-gain and offset matching, characteristics that make it suitable in either I/Q baseband or direct IF communication application.
