OVERVIEW
The S9518 DACPOT trimmer is an 8-bit nonvolatile DAC designed to replace mechanical potentiometers. The S9518 includes a unity-gain amplifier to buffer the DAC output and enables VOUTto swing from rail to rail. The DACPOT trimmer operates over a supply voltage range of 2.7V to 5.5V.

FEATURES
Digitally Controlled Electronic Potentiometer
• 8-Bit Digital-to-Analog Converter (DAC)
– Independent Reference Inputs
– Differential Non-Linearity of ±0.5LSB max
– Integral Non-Linearity of ±1LSB max
•VOUTValue in EEPROM for Power-On Recall
– Equivalent to 256-Step Potentiometer
• Unity Gain Op Amp Drives up to 1mA
• Simple Trimming Adjustment
– Debounced Pushbutton Interface
• Low Noise Operation
• “Clickless” Transitions between DAC Steps
• No Mechanical Wear-out Problem
– 1,000,000 Stores (typical)
– 100 Year Data Retention
• Operation from 2.7V to 5.5V Supply
• Low Power: 1mW max at 5V
