FEATURES • Digitally Controlled Electronic Potentiometer • 7-Bit Digital-to-Analog Converter (DAC) – Independent Reference Inputs – Differential Non-Linearity - +0.5LSB – Integral Non-Linearity - +1LSB •VOUT Value in EEPROM for Power-On Recall – Equivalent to 128-Step Potentiometer • Unity Gain Op Amp Drives ±100µA • Simple Trimming Adjustment – Up/Down Counter Style Operation • Low Noise Operation • “Clickless” Transitions between DAC Steps • No Mechanical Wearout Problem – 1,000,000 Stores (typical) – 100 Year Data Retention • Operation from +2.7V to +5.5V Supply • Ultra-Low Power, 0.5mW max at +5V Nonvolatile DACPOT™ Electronic Potentiometer With Up/Down Counter Interface SMP9317 OVERVIEW The SMP9317 DACPOT™ trimmer is a 7-bit nonvolatile DAC designed to replace mechanical potentiometers. The SMP9317 includes a unity-gain amplifier to buffer the DAC output and enables VOUT to swing from rail to rail. The DACPOT trimmer operates over a supply voltage range of 2.7V to 5.5V. The SMP9317’s simple up/down counter input provides an ideal interface for automatic test equipment to dither and monitor the VOUT voltage. This interface allows for quick and consistent calibration of even the most sophis- ticated systems. The SMP9317 is a pin-compatible performance upgrade for other industry nonvolatile potentiometers. The SMP9317 offers higher resolution than these devices and provides ‘clickless’ transitions of VOUT.
