Overview
The MAX155AEWI+ is a high-performance, 8-bit, multichannel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX155 series, which is known for its simultaneous track-and-hold (T/H) inputs, eliminating timing differences between input channel samples. The MAX155AEWI+ features 8 analog input channels, each with its own T/H, allowing for precise and synchronized sampling of multiple channels.
