Overview
The MAX113CAG+T is a microprocessor-compatible, 8-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX113/MAX117 series, which includes 4-channel and 8-channel ADCs. The MAX113 operates from a single +3V supply and utilizes a half-flash technique to achieve a fast conversion time of 1.8µs per channel, corresponding to a sampling rate of 400ksps. It is designed for low-power applications, with a power-down mode that reduces current consumption to 1µA typical. The device includes a track/hold function, enabling it to digitize fast analog signals, and features ratiometric reference inputs for precise measurements.
