Product Details
MAX22191AUT+T - Analog Devices Ultra-Low-Power Digital Input Translator
The MAX22191AUT+T is an ultra-low-power industrial Digital Input Translator from Analog Devices. Designed for IEC 61131-2 compliant industrial input applications, it translates 24V field signals into CMOS-compatible logic outputs while operating without a dedicated field-side power supply. Packaged in a compact SOT-23-6 package, the MAX22191AUT+T is ideal for industrial automation, motor control, process control systems, and isolated digital input modules.
Product Overview
The MAX22191AUT+T is a parasitically powered industrial digital input device capable of converting 24V industrial switching signals into standard 3.3V or 5V CMOS-level outputs. The device derives its operating power directly from the field input signal, eliminating the need for an additional field-side power supply and reducing system complexity.
