Luminosity Adjustment for Various
Types of Equipment
The TPS820 is a linear output photo-IC (current
output type) which incorporates a photodiode and a
current amp circuit in a single chip.
The sensitivity is superior to that of a
phototransistor and its illuminance output linearity
is excellent.
High sensitivity: I
L
= 2.5 mA (typ.) @E = 0.1
mW/cm
2
Little fluctuation in light current
Output linearity of illuminance is excellent.
Low current consumption: I
CC
= 1 A (max) at
V
CC
= 5 V
Housed in compact side-view epoxy resin
package
Black package impermeable to visible light
The TPS820 is suitable for use in combination
with the TLN117 infrared LED lamp whose
package size is the same.

Precautions
When this device is used in combination with an LED lamp, the lamp must be an infrared LED lamp.
To stabilize the power line, insert a bypass capacitor of up to 0.01 mF between V
CC
and GND, close to the device.
When the power is turned on, the output value will fluctuate for 1 ms as the internal circuit stabilizes.
