Product Information

Back to top
The HAL 880 is designed to fulfill the requirements of today’s state-of-the-art applications for linear and angular measurements that require flexibility to compensate system tolerances.

Its compensation of system tolerances is due to its programmability. This is mandatory for applications like accelerator pedal sensing, current measurement, bending light, or head light adjustment. The sensor provides a linear, ratiometric analog output signal with implemented wirebreak detection working with pull-up or pull-down resistor.

Major characteristics like magnetic-field range, sensitivity, VOQ (output voltage at zero magnetic field) and the temperature coefficients can easily be adjusted to the magnetic circuit (linear and quadratic) by programming the non-volatile memory.
The HAL 880 is available in the leaded package TO92UT or in the SMD package SOIC8.

The HAL 880 sensors are produced in a proven submicron CMOS technology.

The HAL 880 features a temperature-compensated Hall plate with choppered offset compensation, an A/D converter, digital signal processing, a push-pull output, an EEPROM memory with redundancy and lock function for the calibration data and the data register information, a serial interface for programming the EEPROM, and protection devices on all pins.

The HAL 880 is programmable by modulating the supply voltage. No additional programming pin is needed.

The internal digital signal processing is of great benefit because analog offsets, temperature shifts, and mechanical stress do not degrade the sensor accuracy.

Major Applications:

• Contactless potentiometers
• Rotary position measurementLinear movementCurrent measurements
