The MAX14890E incremental encoder receiver contains four differential receivers and two single-ended receivers.The differential receivers can be operated in RS-422 or differential high-threshold logic (HTL) modes and are optionally configurable for single-ended TTL/HTL operation. The MAX14890E features a wide common mode input range of -20V to +20V in RS-422 mode.The auxiliary IEC 61131-2 Type-1/Type-3 digital inputs are designed for operation with switches or proximity sensors and can be individually configured for TTL operation.All receiver input signals are fault protected to voltage shorts in the ±40V range. Per channel fault detection provides warning of irregular conditions such as small differential signals, shorts, opens, overvoltages, and undervoltages.The MAX14890E features a pin-selectable SPI or parallel-logic interface. SPI control provides detailed diagnostics and individual configurations for receivers.The MAX14890E is available in a 32-pin TQFN-EP (5mm x 5mm) and operates over the -40°C to +125°C temperature range.ApplicationsEncoder InterfacesMotor ControllersPulse CountersServo Control Commutation
