Overview
The ADS8318IDGSTG4 is a 16-bit, 500-kHz sampling rate analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the microPOWER™ series and is designed for low-power, high-performance applications. It operates with a 2.048-V to 5.5-V external reference and features a capacitor-based, successive-approximation register (SAR) A/D converter with inherent sample and hold capabilities. The ADS8318IDGSTG4 is available in 10-pin MSOP and SON packages, making it suitable for a variety of compact and power-efficient designs.
