Overview
The MAX156ACWI+ 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/MAX156 series, with the MAX156 specifically featuring 4 analog input channels. Each channel has its own track/hold (T/H) circuit, allowing for simultaneous sampling to eliminate timing differences between input channel samples. The ADC is capable of converting a channel in 3.6µs and stores the result in an internal 8x8 RAM. It supports both unipolar and bipolar, single-ended or differential conversions and operates from a single +5V supply or dual ±5V supplies for wider dynamic range or bipolar conversions around ground.
