Overview
The MAX155BEWI, produced by Analog Devices Inc./Maxim Integrated, is a high-speed, 8-bit, multichannel analog-to-digital converter (ADC) designed for simultaneous sampling of multiple analog input channels. This component is part of the MAX155 series, which features 8 analog input channels, each with its own track/hold (T/H) circuit. This design ensures that all T/Hs sample at the same instant, eliminating timing differences between input channel samples. The MAX155BEWI operates from a single +5V supply or dual ±5V supplies, supporting both unipolar and bipolar input ranges, as well as single-ended or differential inputs.
