IQS370
The IQS370 ProxSense® IC is a four channel I2C inductive sensing device.This IC is aimed at inductive sensing applications that require an absolute encoder / slider. The sensor is fully I2C compatible and on-chip calculations enable the IC to respond effectively even in its lowest power mode.
