Overview
The MAX113EAG+ is a microprocessor-compatible, 8-bit, 4-channel analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device operates from a single +3V supply and utilizes a half-flash technique to achieve a fast conversion time of 1.8µs, resulting in a sampling rate of 400ksps. The MAX113 is designed for low-power applications, with a power-down mode that reduces current consumption to 1µA typical. It features a track/hold function, enabling the digitization of fast analog signals, and its microprocessor interface is simplified, allowing it to appear as a memory location or I/O port without external interface logic.
