FM-A038□□-5CN
IR Receiver Modules for Remote Control Systems
Description
The FM-A038□□-5CN is a Bi-CMOS IC for use in infrared
remote control system.
Small-sized, light-weight, and low current consumption.
modules have been achieved by using resin mold.
The demodulated output signal can directly be decoded
by a microprocessor. The main benefit is the reliable
function even in disturbed ambient and the protection
against uncontrolled output pulses.
Features
 Photo detector and preamplifier in one package.
 Supply Voltage Range: 2.7V to 5.5V
 Internal filter for PCM frequency
 Insensitive to supply voltage ripple and noise
 Improved shielding against EMI (Built-in Shield Case)
 Improved immunity against ambient light
 Open collector output [ built-in Pull-up resistor(40K) ]
 Enhanced Immunity against all kinds of disturbance light
 Meet RoHS
Applications
Block Diagram
 TV, VCR, AUDIO
 Home Appliances
 Remote Control Equipment
Application Circuit (for power supply ripple suppression & ESD protection)
Component
Recommend
1) RS
Typ. 100Ω (47Ω~470Ω)
2) Cp1
Typ. 100uF (47uF~470uF)
3) Rp
Optional (10kΩ or more)
4) Cp2
Typ. 1nF (1nF~10nF)
5) D1~D3
Zener diode or TVS
(ESD Protection device)
Note:
A further influence to the IR receiver modules may come from a supply voltage which is not stable. Such a disturbed supply voltage can caused by
switching power supply. which is not filtered well or by other components in the circuit which produced spikes on the supply line.
This disturbed supply will reduce the sensitivity of receiver modules.
This application circuit will filter the disturbed supply voltage.

Note :
1) Arrival Distance Effected by Environment
2) While the device is operational across the temperature range, functionality will vary with temperature.
Specifications are stated only at 25°C unless otherwise noted.
3) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
