| NJM2650 HALL AMPLIFIER IC sGENERAL DESCRIPTION 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. sPACKAGE OUTLINE NJM2650V sFEATURES *Position Sensing Output *Chip Enable *Hall Bias Stand-By Function *Open Collector Output *Bipolar Technology *Package Outline SSOP10 sPIN CONFIGURATION 1 2 3 4 5 10 9 8 7 6 NJM2650V PIN Function 1.
