The HAL 880 complements the existing Hall-effect sensor family HAL 8xy to the lower end. It is designed to fulfil the requirements of today’s state-of-the-art applications for linear and angular measurements that require programmability to compensate system tolerances.

Main Features
◆ Sensitivity drift over temperature less than ±6%
◆ Offset drift over temperature less than ±15 μT/K
◆ Integral non-linearity error of output signal ±1% of VDD
◆ Ratiometric error of output signal ±1%
◆ Low output noise of 25 mV peak-peak
◆ Wire-break detection with 5 kΩ pull-up or pull-down resistor
◆ Four programmable magnetic ranges: ±30, ±60, ±80, and ±100 mT
◆ Two programmable 3 dB filter frequencies: 500 Hz and 1 kHz
◆ Programmable sensitivity and offset (VOQ)
◆ 12-bit ratiometric analog output
◆ Digital signal processing
◆ Temperature characteristics programmable to match all common magnetic materials
◆ 13 customer data bits
◆ Programming by modulation of the supply voltage
◆ Operates from –40 °C up to 140 °C junction temperature
◆ Operates from 4.5 V up to 5.5 V supply voltage
◆ Magnetic characteristics extremely robust against mechanical stress

Major Applications
◆ Due to the sensor’s versatile programming characteristics, the HAL 880 is the optimal system solution for applications such as:
– Contactless potentiometers
– Rotary position measurement
– Linear movement
– Current measurements
