SUMMIT MICROELECTRONICS, Inc. Dual 10-bit Nonvolatile DAC In-system Programmable Analog FEATURES Two 10-bit Nonvolatile DACs − INL ± 1LSB − DNL: ± 1LSB Programmable Configuration Programmable Power-on Reset Options − Recall Full Scale Value − Recall Zero Scale Value − Recall Mid-Scale Value − Recall NV Register Value Tandem or Independent Operation of DACs Power-down mode (short VOUT to gnd) SMP9210 SMP9211 SMP9212 ISPa™ OVERVIEW 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.
