Overview
The ADS8328IBPWG4 is a low-power, 16-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the ADS8328 family and is designed for high-speed and low-power applications. It features a 16-bit capacitor-based successive approximation register (SAR) ADC with inherent sample and hold, and it includes a 2-to-1 input multiplexer (MUX) with programmable TAG bit output. The ADS8328 is available in 16-lead TSSOP or 4×4 QFN packages and is fully specified for operation over the industrial temperature range of –40°C to +85°C.
