Test Procedure for the LA0152CSGEVB Evaluation Board 28/Mar/2012 Evaluation Board Photo Diode IC1 4pin OUT C1 0.1μＦ R1 33KΩ 1pin VCC 2pin EN 3pin GND Monitoring or To CPU AD port EN Low High 12/23/20132 State Sleep Active 1 www.onsemi.com LIGHT SOURCE ILLUMINANCE METER GND OUT EN VCC 01.3200 V DC MULTIMETER POWER SUPPLY Test Procedure: 1. 2. 3. 4. 5. 6. Connect the test setup as shown above. Connect IC power supply (2.2V to 5.5V) between VCC and GND. Connect multimeter between OUT and GND. Irradiate a light, and put on the illuminance meter near the IC. Control the light source and to be adjusted 500 lux. Then, OUT terminal of LA0152CS is outputted roughly 40uA. Therefore, multimeter is showed roughly 1.32V. (1.32V = 40uA×33kΩ） LA0152CS features: ・No sensibility in infrared area. ・Less difference in sensibility depending on the type of light source. 12/23/20132 2 www.onsemi.com 12/23/20132 3 www.onsemi.com
