Overview
The Texas Instruments ADS8332IPW is a low-power, 16-bit analog-to-digital converter (ADC) designed for high-performance applications. This device is part of the ADS8332 series and features a unipolar 8-to-1 input multiplexer (mux). It is based on a 16-bit capacitor-based successive approximation register (SAR) ADC with inherent sample and hold capabilities. The ADS8332IPW operates over a flexible analog supply range of 2.7V to 5.5V and is available in 24-pin TSSOP and VQFN packages, making it suitable for a wide range of industrial and commercial environments.
