AP1355AEM
Amplifier for Hall Element
1. General Descriptions
AP1355AEM is an amplifier specially designed for Hall Element. The AP1355AEM integrates built-in
current source for driving a Hall Element and amplifier for Hall output. The current source and offset voltage
of Hall Element are controllable by external voltage supply, so as to calibrate characteristics of Hall Element
and to calibrate errors after installation of Hall element to the system.

Functions
It amplifies the generated voltage of Hall Element. It can change the gain by making the
short circuit between TR1 pin and TR2 pin.
It adjusts the offset of the amplifier output. The offset is adjustable by inputting the
voltage to VOS pin.
It outputs the reference voltage (5V). Its voltage is supplied for the power supply of
DAC.
It supplies the current to the hall element. The current is adjustable by inputting the
voltage to VISET pin.
D/A Converter (AK9820CTH)
AK9820CTH inputs the voltage to the offset calibration circuit, and sets up the current for Hall Element.
