General Description
The AK9754 is an ultra-low power and ultra-small quantum infrared-ray (IR) sensor module with signal processing circuits and Human Approach Detection algorithm. It can detect a human approach and outputs a signal from interrupt pins. An integral analog-to-digital converter provides 16-bits data outputs. Human detection can be easily realized by using built-in Human Approach Detection algorithm. The AK9754 is suitable for human sensing application.

FEATUREs
□ Quantum-type IR Sensor
□ Integrated Temperature Sensor: -30 to 85ºC Output on I2C bus
□ 16-bits Digital Outputs to I2C Bus
□ Integrated Digital Filters:
   IR Sensor: Cut-off Frequency 0.9Hz, 0.445Hz
   Temperature Sensor: Cut-off Frequency 0.9Hz, 0.445Hz
      * Only with 10Hz of Data Output Rate(ODR)
□ I2C Interface:
   Support Standard mode(100Hz) and Fast modes(400Hz).
   *Pull-up resistors must be connected to the same level as the power supply of the AK9754.
□ Multiple Synchronization Connection:
   Eight devices can be connected in synchronization at maximum, and setting I2C bus slave
   addresses for each.
□ Interrupt Function:
   INTN pin goes to active when detecting a human approach or measurement data is ready to be
   read.
□ Power Supply: 1.71 to 3.63V
□ Low Consumption Current:
   10 µA (Max.) 10Hz of Data Output Rate (Low-noise Mode OFF)
   5 µA (Typ.) 10Hz of Data Output Rate (Low-noise Mode OFF)
                                   *TOPT[1:0] = 11B
□ Ultra-small and Thin Package: 8-pin SON
