The light used is a CIE Standard A light source (a standard tungsten bulb with a color temperature of 2856°K). Handling Precautions • When using the device with an LED, use an infrared LED. Note that light with a wavelength of 800 nm or less cannot be detected. • Do not use the device in an environment where the external light is 3000 lx or more, as this may prevent the device from working properly. • At power-on the internal circuit takes about 100 μs to stabilize. During this period the output signal is unstable and may change. Design the circuit so that no signal is output during this period. • The photo-IC has a highly sensitive amp built in. To stabilize the power line, insert a bypass capacitor of up to 0.01 μF between VCC and GND, close to the device. • If the LED is directly connected to the LEDOUT pin, excessive current will flow in the LED, severely degrading the optical output. Be sure to insert a limiting resistor to prevent excessive current flow in the LED. • When forming the leads, bend each lead under the lead stopper. Soldering must be performed after the leads have been formed. • Soldering must be performed under the stopper. 3 2007-10-01 TPS816(F) VOL – IOL (typ.)
