Overview
The ADS8330IBPWG4 is a low-power, 16-bit, 1-MSPS analog-to-digital converter (ADC) produced by Texas Instruments. This device is based on a 16-bit capacitor-based Successive Approximation Register (SAR) ADC with inherent sample-and-hold functionality. It features a 2-to-1 input multiplexer (MUX) and supports programmable TAG bit output. The ADS8330 is designed for high-speed and low-power applications, making it suitable for various industrial and medical uses.
