6.2 Magnetic Input Range
The magnetic input range is defined by the AGC loop. This regulating loop keeps the Hall sensor output in the optimum range for low SNR by
adjusting the Hall bias current. This loop can adjust to a magnetic field strength variation of ±38%. The AGC output voltage is an indicator for the
magnetic field.
The nominal magnetic field for a balanced AGC is defined by the Hall bias and the Hall sensitivity and can be set by a variable gain in the signal
path. The gain can be set in 8 steps in the OTP or by the SSI in a mirror register. The resulting magnetic input range is a value of B
inside of a range of 32mT …75mT, if the trimming is performed by the customer.
