The AK9750 is an ultra-low power and compact infrared-ray (IR) sensor module. It is composed of four quantum IR sensors and an integrated circuit (IC) for characteristic compensation.
The four IR sensors' offset and gain variations are calibrated at shipment. An integral A/D converter provides 16-bits data outputs.
Additional integrated features include a field of view limiter and an optical filter. The AK9750 is suitable for applications including stationary human detection.


Key Features

● Quantum-type IR Sensor with Four IR Elements

● 16-bits Digital Outputs to I2C bus

● Interrupt Function: INT pin can be used as a read-trigger or an interrupt request of signal level monitoring.

● Built in Switch Mode: By writing the threshold into the internal EEPROM at the customer’s production testing, the presence detection state will be output to the INT pin. In this mode, neither the control by I2C bus nor Host MCU is necessary.

● Integrated temperature sensor: -10 ~ 60ºC output on I2C bus

● Low Voltage Operation: VDD: 1.71 ~ 3.63V
DVDD: 1.65V ~ VDD

● Low Current Consumption: Max.100 µA (@Continuous Mode)
Max. 1µA (@ Power down Mode)

● Small and Thin Package: 10-pin SON
Built in a field of view limiter and an optical filter
