Overview
The MAX1067AEEE+T is a low-power, multichannel, 14-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device features a successive-approximation ADC architecture and is designed for applications requiring high dynamic performance, low power consumption, and ease of use. The MAX1067 includes a 4-channel input multiplexer and operates with a single +5V analog supply, along with a separate digital supply that can interface directly with +2.7V to +5.5V digital logic.
