LDC5071-Q1 is a high-speed and accurate inductive sensor used for measuring absolute linear and rotary position in automotive and industrial applications. The device is designed to interface to three inductive sensing coils that are typically on the printed circuit board. One of the coils is connected to the exciter circuit of the LDC5071-Q1 and acts as a transmitter, and the other two secondary coils are used as receivers. The transmitter coil induces a voltage in the secondary coils, which is a function of the conductive target above the sensor coils. The demodulated signals which are produced during LDC5071-Q1 operation are then provided through the differential signal path with sine and cosine outputs.

The LDC5071-Q1 has multiple supply options, 5-V or 3.3-V, to suit different design options and can be connected to a microcontroller to calculate the rotary angle. The manual and automatic gain control (AGC) of the LDC5071-Q1 can be used to control and maximize the dynamic range of the outputs.

The device offers robust protection features to support and monitor signals and overall device operation for a seamless systems protection. The LDC5071-Q1 supports overvoltage, reverse battery and current protection on short to high voltage on output pins. In addition, the device provides immunity against motor noise and can filter out-of-band low- and high-frequency noise.
