INTRODUCTION
The SMP9410 is a quad 10 bit (1024 steps) Non Volatile
D-to- A converter or DACPOT^TM. The device will recall any
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,
and I²C bus industry standard 2-wire serial interface. The
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.
