Overview
The MAX118CPI+ is a microprocessor-compatible, 8-bit, 8-channel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device 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 features a power-down mode that reduces current consumption to typically 1µA, making it suitable for power-sensitive applications. The ADC includes a track/hold circuit, enabling it to digitize fast analog signals efficiently.
