NJL71H/71V/72H/73H/74H000A
INFRARED REMOTE CONTROL RECEIVER
s GENERAL DESCRIPTION
The NJL70H/V000A series are small and high performance receiving devices for infrared remote control system.
They can operate under low and wide supply voltage (2.4V to 5.4V). Also, their supply current is low comparing to the
NJL60H/V000A and NJL80H/V000A.
The features, low and wide supply voltage, low supply current are suitable for battery operated items.
s FEATURES
1. Wide and low supply voltage 2.4V to 5.5V
2. Low supply current
0.6mA max.
3. Mold type and metal case type to meet the design of front panel.
4. Line-up for various center carrier frequencies.
s APPLICATIONS
1. AV instruments such as Audio, TV, VCR, CD, MD etc.
2. Home application such as Air-conditioner, Fan etc.
3. Battery operated instruments such as Toy, Camera etc.

s TEST METHOD
Test condition in as follows:
(1) Standard transmitter:
Transmitting waveform is shown in Fig.1
Transmitting power should be adjusted
so that output voltage Vout will be
400mVp-p.(Test circuit is shown in Fig.2)
Regarding IR LED used for transmitter,
λp=940nm, ∆λ=50nm.
Regarding photo diode,
Sensitivity S=26nA/Lx
in case light source temperature2856°K,
Ee=100Lx, VR=5V
