NJM2650
HALL AMPLIFIER IC
■GENERAL DESCRIPTION
■PACKAGE OUTLINE
The NJM2650 is a dual hall amplifier IC for converting
signals from hall sensors to digital signals.
It is suitable for speed and position sensing of motor
control system using DSP or micro controllers.
The NJM2650 can turn off the amplifier block and bias
supply of hall device at the standby. Therefore, the
consumption current of the application can be reduced.
