8.2 Automatic Gain Control (AGC)
As the magnetic input field varies non-linearly with the air gap between sensor and magnet, the gain is controlled to an optimum input signal for
the SD ADC. The magnitude output is compared to a target register value. The most significant eight bits are used. If the actual magnitude differs
from the target value, an UP/DOWN signal for the AGC counter signal is generated.
For air gap detection functionality, two magnitude-change outputs are derived from the AGC counter UP/DOWN signals while the loop is
controlling the amplitude back to the target amplitude. Magnitude Increasing (MagINCn) and Magnitude Decreasing (MagDECn) signals indicate
air gap (SIN/COS amplitude) changes. Both signals are high for saturation of the AGC counter (running into upper / lower limit) and produce a
Non-Valid-Range alarm. The output pins can be connected together in wired-OR configuration to produce a single NVRn bit. For faster power-up
and response time, a successive approximation algorithm is implemented.
8.3 Temperature Sensor
The Temperature Sensor provides the junction temperature information over the serial interface.
Table 10. Temperature Sensor Characteristics
8.4 I²C User Interface
The device is accessible via an I2C two-wire serial interface. The default address is A<6:0>1000000. A<5:1> can be defined by the OTP I2C
Address. A0 can be selected by pulling up pin 11 (default internal pull down). CSn must be low during I²C data transmission (not connected /
internal pull down).
