Overview
The LTC1856IG#PBF is a high-performance, 8-channel analog-to-digital converter (ADC) produced by Analog Devices Inc. This 16-bit successive approximation register (SAR) ADC is designed for low power consumption and high accuracy, making it suitable for a variety of applications requiring precise analog-to-digital conversion.
The device operates from a single 5V supply and features an on-board precision reference, which minimizes the need for external components. It supports single-ended inputs, pairs of differential inputs, or combinations of both, and all channels are fault-protected to ±30V.
