Preliminary Information

Quad 10-Bit Nonvolatile DACPOT^TM

FEATURES

INTRODUCTION

l Four Programmable 10-Bit Nonvolatile DACs

w INL ±1LSB, DNL ±1LSB, 1024 Steps Each

l Power on Recall at any Value

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

D-to-AconverterorDACPOT^TM.Thedevicewillrecallany

analog voltage on power up, making it ideal for high

accuracyandtemperaturestablecalibrationpurposesand

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.

l Parallel or Independent Operation of DACs

l Excellent Temperature Stability - ±15ppm/ C

Industrial Temperature range

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

cuits: anenhancedunitygainoperationalamplifieroutput,

a10-bitvolatiledatalatch,a10-bitnonvolatiledataregister,

and I²C bus industry standard 2-wire serial interface. The
