Overview
The MAX111ACWE+T is a 14-bit, low-power, analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This component is part of the MAX110/MAX111 family of ADCs, known for their high resolution and low power consumption. The MAX111 operates with a single +5V supply and is capable of converting differential analog signals in the ±1.5V range or single-ended signals in the 0V to +1.5V range. It features an internal auto-calibration technique, eliminating the need for external components to achieve its 14-bit resolution plus overrange.
