Product Introduction

Overview

The MAX156BCNG+ 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 family, which features simultaneous track/holds (T/Hs) to eliminate timing differences between input channel samples. The MAX156 specifically has 4 analog input channels, each with its own T/H, allowing all channels to sample at the same instant. The ADC converts a channel in 3.6µs and stores the result in an internal 8x8 RAM. It also includes a 2.5V internal reference and power-down capability, making it a complete sampling data-acquisition system.
