AH8502中文资料linear-hall-effect-sensors数据手册Diodes规格书

描述 Description

The AH8502 is a micropower power linear Hall effect sensor with output voltage of 8-bit resolution. The output voltage is ratiometric to the supply voltage and proportional to the magnetic flux density perpendicular to the part marking surface. The output null point is at half the supply voltage. 

\t 

\tAH8500 has a typical sensitivity of 2.1mV/G and 3.55mV/G at 1.8V and 3V. The typical null voltage offset is less than 1% of VDD. The device has typical input referred rms noise of 0.36G and 0.24G at 1.8V and 3.0V.

\t 

\tDesigned for battery powered consumer equipment to office equipment, home appliances and industrial applications, the AH8502 can operate over the supply range of 1.6V to 3.6V. The device has a CNTRL pin to select the operating modes and sampling rate to minimize power consumption. The device operates in default micropower mode with sampling rate of 24Hz typical and consumes only 13uA typical at 1.8V. In turbo mode with continuous 6.25kHz sample rate the current consumption is 1mA typical. In external-drive mode, the CNTRL be can be used to change the sampling frequency up to 7.14KHz with current consumption of 1.16mA typical at 1.8V.

\t 

\t 

\tTo minimize PCB space the AH8502 is available in small low profile U-DFN2020-6.
