Overview
The MAX116CAX, produced by Analog Devices Inc./Maxim Integrated, is a high-speed, multichannel, 12-bit data-acquisition system (DAS) with simultaneous track/holds (T/Hs). This device is part of the MAX115/MAX116 family and is designed for applications requiring fast and precise analog-to-digital conversion. It features a 12-bit, 2µs successive-approximation analog-to-digital converter (ADC), a +2.5V reference, a buffered reference input, and a bank of four simultaneous-sampling T/H amplifiers. These amplifiers preserve the relative phase information of the sampled inputs and allow for a total of eight single-ended inputs through two multiplexed inputs for each T/H amplifier.
