Amplifier for Hall Element
Since the market demand for high accuracy current sensor for industrial equipment such as AC servo motor is increasing, AKM has developed an Amplifier for Hall Element, the AP1355AEM.
It can calibrate variations and installation errors of a hall element. A high accuracy current sensor can be configured easily by combining the AP1355AEM at the post processing stage of the AKM’s hall element HG-series. In addition, an automatic calibration system at power-up can be implemented by combining AKM’s DAC, the AK98xx that has built-in EEPROM to store a calibration value.
|Power Supply||Amplifier Gain||Offset Voltage Calibration Range||Package||Oper.Temp.|
|AP1355AEM||±13.5 to ±16.5||GainA=180, GainB=95||±1.85||TSSOP-16||-40 to 105|
