Overview
The MAX110ACAP+ is a low-cost, 2-channel, 14-bit serial analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX110 series, known for its high resolution and low power consumption, making it ideal for battery-powered or remote-sensing applications. The MAX110ACAP+ utilizes an internal auto-calibration technique to achieve 14-bit resolution plus overrange without the need for external components. It operates with ±5V supplies and can convert differential analog signals in the -3V to +3V range.
