MP Motion Sensor (AMN2, 3, 4)

2. Absolute maximum ratings (Measuring condition: ambient temperature = 25

3. Electrical characteristics (Common to All types)

1) Digital output

Note: The current which is consumed during detection consists of the standby consumed current plus the output current.

2) Analog output

Note: To set to the same detection performance as the digital output type, set the output voltage to the offset voltage (2.5V)

±0.45V (i.e. 2.95V or more and 2.05V or less).

1. Digital output

Note: Circuit stability time: 30s max.

While the circuitry is stabilizing after the power is turned on, the sensor output

is not fixed in the “on” state or “off” state. This is true regardless of whether or

not the sensor has detected anything.
