High Precision Programmable Hall Sensors HAL82x

This HAL 824 and the HAL 825 complement the existing
Hall sensor family HAL 8xy. Both high-precision magnetic field
sensors provide a ratiometric, linear output signal. This sensor
family is designed to fulfil high requirements in respect of low
temperature drifts of sensitivity and offset.
Due to the very low drifts of this sensor family, it can be used for
applications with very high requirements on offset and sensitivity
drift stability. This is mandatory for applications like throttle
position detection, accelerator pedal sensing or current
measurement. The sensors provide either a ratiometric analog
output signal or a multiplexed analog output. in multiplex analog
output mode, the sensors transmit a signal with 14-bit accuracy.
Major characteristics like magnetic field range, output format,
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. Both sensors are available in the very small leaded
package TO92UT.
