Overview
The MAX111BCAP+T is a high-performance analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX110/MAX111 family, known for its high resolution and low power consumption. The MAX111 operates with a single +5V supply and is designed to convert 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, which ensures 14-bit resolution plus overrange without the need for external components. This ADC is ideal for high-resolution battery-powered or remote-sensing applications due to its low power consumption and compact packaging.
