Overview
The MAX1167CCEE+ is a low-power, multichannel, 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device features a successive-approximation ADC, an integrated +4.096V reference, a reference buffer, an internal oscillator, and automatic power-down capabilities. It operates with a single +5V analog supply and has a separate digital supply, allowing direct interfacing with +2.7V to +5.5V digital logic. The MAX1167 is designed for applications requiring high precision, low power consumption, and compact packaging, making it ideal for control and data-acquisition operations.
