The MPR083 is an Inter-Integrated Circuit Communication (I2C) driven Capacitive Touch Sensor Controller, optimized to manage an 8-position rotary shaped capacitive array. The device can accommodate a wide range of implementations through 3 output mechanisms, and many configurable options.

*1.8 V to 3.6 V operation
*41 μA average supply current with 1 s response time
*2 μA Standby Current
*Variable low power mode response time (32 ms – 4 s)
*Rejects unwanted multi-key detections from EMI events such as PA bursts or user handling
*Ongoing pad analysis and detection is not reset by EMI events
*Data is buffered in a FIFO for shortest access time
*IRQ output advises when FIFO has data
*System can set interrupt behavior as immediate after event, or program a minimum time between successive interrupts
*Current rotary position is always available on demand for pollingbased systems
*Sounder output can be enabled to generate key-click sound when rotary is touched
*Two hardware selectable I2C addresses allowing two devices on a single I2C bus
*Configurable real-time auto calibration
*5 mm x 5 mm x 1 mm 16 lead QFN package
*-40°C to +85°C operating temperature range
*Control Panels
*Switch Replacements
*Rotary and Linear Sliders

Typical Applications
*PC Peripherals
*Access Controls
*MP3 Players
*Remote Controls
*Mobile Phones
