注意事项：Notice

1. 错误的接线可能导致传感器损坏。传感器接 5V 电源后，被测电流从传感器箭头方向穿过，即可在 输出端测得相对应的电压值。

Incorrect wiring may cause damage to the sensor. After the sensor is connected to a 5V power supply, the measured current passes through the arrow direction of the sensor, and the corresponding voltage value can be measured at the output end.

2. -BR：输出电压 VOUT 是与供电电压 VCC 成正比例关系，VOUT   = VCC⁄2 + 2 × Ip⁄I               ，供电电压变

化，会引起 VOUT 等比例的变化。

-BR: The output voltage VOUT is directly proportional to the power supply voltage VCC, VOUT = VCC⁄2 + 2 × Ip⁄I, the change of the power supply voltage will cause the VOUT proportional change.

例如：VCC 范围 4.75V~5.25V；对应 0A 下的静态输出电压 VQVO 输出范围为 2.375V~2.625V 。满 量程 VOUT(IPMAX)的输出范围为 4.375V~4.625V。

                   For example, the VCC ranges from 4.75V to 5.25V. The corresponding static output voltage VQVO at 0A ranges from 2.375V to 2.625V. The output range of full-scale VOUT(IPMAX) is 4.375V to 4.625V.
