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:
