Description:
The MCP2036 Inductive Sensor Analog Front End (AFE) combines all the necessary analog functions for a complete inductance measurement system.

The device includes:
• High-frequency, current-mode coil driver for
   exciting the sensor coil.
• Synchronous detector for converting AC sense
   voltages into DC levels.
• Output amplifier/filter to improve resolution and
   limit noise.
• Virtual ground reference generator for single
   supply operation.

The device is available in 14-pin PDIP, SOIC and 16-pin QFN packages:

FEATUREs:
• Complete Inductance Measurement System:
   - Low-Impedance Current Driver
   - Sensor/Reference Coil Multiplexer
   - High-Frequency Detector
• Operating Voltage: 2.7 to 5.5V
• Low-Power Standby Mode
• Gain and Frequency set by external passive
   components

Typical Applications:
• Harsh environment inductive keyboards
• Inductive rotational sensor interface
