MAX14890EATJ+T Description

Short technical summary and product information.

The MAX14890EATJ+T is an incremental encoder receiver IC manufactured by Analog Devices. This device features four differential receivers and two single-ended receivers, capable of operating in RS-422 or differential high-threshold logic (HTL) modes. It supports selectable RS-422/HTL/TTL/DI receivers with RS-422/TTL switching rates up to 35Mbps and HTL switching rates up to 400kHz.

 

The receiver offers a wide common mode input range of -20V to +20V in RS-422 mode and includes integrated fault detection for open-wire, short-circuit, overvoltage, and undervoltage conditions. The input signals are fault protected to ±40V.

 

Designed for flexibility, the MAX14890EATJ+T features a pin-selectable SPI or parallel logic interface, allowing for detailed diagnostics and per-receiver configurations via SPI. It operates over a temperature range of -40°C to +125°C and is available in a 32-pin TQFN-EP (5mm x 5mm) package, suitable for surface mounting.

 

Applications for this receiver include encoder interfaces, motor controllers, pulse counters, and servo control commutation.
