TIDA-00580 Reference Design

Texas Instruments

Automotive-Qualified 16-Bit Rotary Quadrature Decoder Reference Design

Description

People prefer to use knobs over touchscreens in many situations.  This solution minimizes the required connections to a microcontroller to monitor a rotary quadrature encoder's direction and distance of rotation.

Features
  •  • Work with any rotary quadrature encoder.•Overvoltage tolerant inputs allow for a wide variety of input voltage ranges.• Voltage translation allows for 2-V to 5-V logic outputs• Open-drain interrupt output indicates to the MCU when a change has occurred.• Low power standby operation.                                                • Freeing up MCU operating time.• Work with any rotary quadrature encoder• Overvoltage tolerant inputs allow for a wide variety of input voltage ranges• Voltage translation allows for 2-V to 5-V logic outputs• Open-drain interrupt output indicates to the MCU when a change has occurred• Low power standby operation• Freeing up MCU operating time
Applications
  • Washer & dryer
  • Process analytics
  • Power analyzer
  • Programmable DC power supply
  • Residential & living fan
