AK9753
IR Sensor IC with I2C I/F
1. General Description
The AK9753 is a 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 analog-to-digital converter provides
16-bits data outputs. The AK9753 is suitable for several feet human detector by using external lens.
2. Features
Quantum-type IR Sensor with Four IR Elements
16-bits Digital Outputs to I2C bus
Integrated temperature sensor:
-10 ~ 60ºC output on I2C bus
Built in Optical filter
Serial Interface: I2CStandard mode and Fast modeCompatible
Interrupt Function
INT pin can be used as a read-trigger or an interrupt request of signal level monitoring.
Built in Switch Mode (Standalone Mode)
By writing the threshold into the internal EEPROM at the customers 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.
Low Voltage Operation:
VDD: 1.71 ~ 3.63V
DVDD: 1.65V ~ VDD
Low Current Consumption:
Max. 100 µA (@Continuous Mode “0)
Max. 1µA (@ Power down Mode)
Small and Thin Package:
10-pin SON
