Overview
The MAX110BCWE+T is a 14-bit, low-power, two-channel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This ADC utilizes an internal auto-calibration technique to achieve high resolution without the need for external components. It is designed for high-resolution battery-powered or remote-sensing applications, featuring a low operating supply current of 550µA and a power-down mode current of 4µA. The device operates with ±5V supplies and converts differential analog signals in the -3V to +3V range, making it suitable for various data acquisition and measurement applications.
