MAX31913AUI+

Sensor And Detector Interfaces Overview

The MAX31913AUI+ is an industrial octal digital input translator and serializer manufactured by Analog Devices Inc./Maxim Integrated. It accepts eight independent high-voltage inputs ranging from 7 V to 36 V and converts them into a serial digital output via an SPI-compatible interface. The device operates with a supply voltage between 7 V and 36 V, drawing a typical operating current of 1.6 mA. It supports data rates up to 500 kb/s and functions within an extended temperature range of -40°C to +125°C. Housed in a 28-pin TSSOP package, it integrates internal reference circuitry for reliable signal translation.
