Infrared Remote Control
Receiver Module
LTM-97 Series
Features
Compact package
High immunity from ambient light
Good performance against electric field disturbance
5 volt supply voltage and low power consumption
Pin out can be changed according to customer's requirement
Description
The LTM-97 series are miniaturized receivers for infrared remote control systems. It is a single unit type module which
incorporates a PIN diode and a receiving preamplifier IC. The demodulated output signal can directly be decoded by
a microprocessor. It has excellent sensitivity and reliable function even in disturbed working environment.

Measuring Method
A. Reception distance measurement
Fig. 1 Reception distance measuring condition
B. Standard transmitter
The transmitter whose output is adjusted up become Vo=400m Vp-p by output waveform as show in Fig. 2 and the
measuring method as shown in Fig. 3 is specified as the standard transmitter. However, the infrared diode to be used
for the transmitter should be
p=940nm,
=50nm.
