The SMP9210 is a serial input, voltage output, dual 10-bit digital to analog converter. It can operate from a single +2.7V to +5.5V supply. Internal precision buffers swing rail-to-rail with an input reference range from ground to the positive supply. The SMP9210 integrates two 10-bit DACs and their associated circuits that include; an enhanced unity gain operational amplifier output, a 10-bit volatile data latch, a 10-bit nonvolatile data register and an industry standard 2-wire serial interface.
