Texas Instruments LMP91300 Proximity Sensor AFE

Texas Instruments LMP91300 Industrial Inductive Proximity Sensor AFE is a complete analog front end (AFE) optimized for use in industrial inductive proximity sensors. The LMP91300 directly converts the RP of the external LC tank into a digital value. The temperature dependence of the sensor is digitally compensated, using an external temperature sensor.

The LMP91300 from Texas Instruments provides programmable thresholds, programmable temperature compensation and programmable oscillation frequency range. Due to its programmability, the LMP91300 can be used with a wide variety of external inductors. Its detection thresholds can be adjusted to the desired detection distances.
