SMP9410 Datasheet | Summit Microelectronics

FEATURES l Four Programmable 10-Bit Nonvolatile DACs M INL ±1LSB, DNL ±1LSB, 1024 Steps Each l Power on Recall at any Value l Parallel or Independent Operation of DACs l Excellent Temperature Stability - ±15ppm/0C .. Preliminary Information 1 see last page INTRODUCTION The SMP9410 is a quad 10 bit (1024 steps) Non Volatile D-to- A converter or DACPOTTM. 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 circuits: 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 values by the user can be simplified with the interface adapter and Windows GUI software obtainable from Summit Microelectronics.
