Datasheet
DESCRIPTION
The MAS9270 is an integrated circuit well suited to
build
Temperature calibration is achieved in three
calibration temperatures only. The trimming is done
through a serial bus and the calibration information
is stored in an internal PROM. This means no
rework for trimming is needed.
