Description

The S9518ST is an electronic component model that falls under the product category of IC Chips. It is an 8-bit nonvolatile DAC (Digital-to-Analog Converter) designed to replace mechanical potentiometers. With a supply voltage range of 2.7V to 5.5V, it includes a unity-gain amplifier to buffer the DAC output, allowing VOUT to swing from rail to rail.
