FEATURES

INTRODUCTION

The SMP9410 is a quad 10 bit (1024 steps) Non Volatile

analog voltage on power up, making it ideal for high

accuracy and temperature stable calibration purposes and

can operate from a single +2.7V to +5.5V supply. Internal

precision buffers swing rail-to-rail with an input voltage

range from ground to the positive supply.

The part integrates four 10-bit DACs and associated cir-

cuits: an enhanced unity gain operational amplifier output,

a 10-bit volatile data latch, a 10-bit nonvolatile data register,

SMP9410 is available in a very small 5mm square Quad Flat

package with No leads (QFN) for small form factor designs.

Programming of configuration, control and calibration val-

ues by the user can be simplified with the interface adapter

and Windows GUI software obtainable from Summit Micro-

electronics.
