Dual 10-Bit Nonvolatile DAC

Summit Microelectronics 

SMP9210, SMP9211, SMP9212

Preliminary

INTRODUCTION

The SMP9210, -11, -12 trio are serial input, voltage

output, dual 10-Bit digital to analog converters. They 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.

They integrate two 10-Bit DACs and their associated

circuits: 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.

Programming of configuration, control and calibration

values by the user can be simplified with the interface

adapter and Windows GUI software obtainable from

Summit Microelectronics.
