Amplifier for Pyroelectric Infrared
Motion Sensor
Pyroelectric infrared sensors are most commonly used in
occupancy sensor applications to control lighting, heating,
ventilation and air conditioning (HVAC) equipment.
The BD9251FV pyroelectric infrared sensor amplifier
integrates a number of essential components in to a single
chip, reducing mounting area, reducing costs and
facilitating design. Features include an integrated regulator,
high precision opamps and comparators.
