Overview
The MAX155BCWI+ is a high-speed, 8-bit, multichannel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This component is part of the MAX155 series, which includes the MAX155 and MAX156 models. The MAX155BCWI+ is specifically designed with 8 analog input channels, each equipped with its own track/hold (T/H) circuit to ensure simultaneous sampling and eliminate timing differences between channel samples.
The ADC features a conversion time of 3.6µs per channel and supports both unipolar and bipolar input ranges, as well as single-ended or differential input configurations. It operates from a single +5V supply or dual ±5V supplies, providing flexibility in various application scenarios.
