Overview
The MAX114ENG+ is a microprocessor-compatible, 8-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX114 series, which includes 4-channel and 8-channel ADCs. The MAX114ENG+ operates from a single +5V supply and is designed for low-power, multi-channel applications.
It utilizes a half-flash technique to achieve a conversion time of 660ns, corresponding to a sampling rate of 1Msps. The device features a power-down mode that reduces current consumption to typically 1µA, making it suitable for power-sensitive applications.
