Overview
The MAX111BCWE+T is a high-performance analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This 14-bit ADC is designed for high-resolution applications and features an internal auto-calibration technique, eliminating the need for external components. It operates on a single +5V supply and can convert both differential and single-ended analog signals. The MAX111BCWE+T is particularly suited for battery-powered and remote-sensing applications due to its low power consumption, with an operating supply current of 550µA and a power-down mode current of 4µA.
