Overview
The MAX155BEWI+T is a high-speed, 8-bit, multichannel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This component is designed with simultaneous track/holds (T/Hs) to eliminate timing differences between input channel samples. It features 8 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.
