Linear output integrated magnetic field sensor temperature compensation circuit
Linear output integrated magnetic field sensor temperature compensation circuit
Constituted by the AD22151 bipolar mode temperature compensation circuit is as shown. The circuit has the following characteristics: ① The temperature compensation resistor R1 is connected between the TC2 side and TC3 side; ② Zero magnetic field is biased on the UCC / 2; ③ It is able to compensate low temperature coefficient below the -500 × 10-6 / ℃. Under the bipolar mode, the curve between the resistance value of R1 and temperature compensation coefficient is shown.
