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.
