Overview
The MAX154BCNG is a high-speed, 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 MAX154BCNG specifically has 4 analog input channels, each with its own T/H, allowing for precise and synchronized sampling.
