Overview
The ADS8332IBPWR is a 16-bit, low-power analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the ADS8332 series, which features a unipolar 8-to-1 input multiplexer (mux) and a 16-bit capacitor-based successive approximation register (SAR) ADC with inherent sample and hold. It is designed for high-speed and low-power applications, making it suitable for a variety of industrial and commercial uses.
