Overview
The MAX114EAG+ 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/MAX118 series, which includes 4-channel and 8-channel ADCs. The MAX114EAG+ operates from a single +5V supply and utilizes a half-flash technique to achieve a conversion time of 660ns, corresponding to a sampling rate of 1Msps. It is designed for low-power applications, featuring a power-down mode that reduces current consumption to typically 1µA. The device can quickly return from power-down mode to normal operating mode in less than 200ns, making it suitable for Burst Mode applications.
