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.
