MECHANICAL DATA
Pinning:
1 = GND, 2 = Carrier OUT, 3 = VS
94 8691
FEATURES
• Photo detector and preamplifier in one package
• AC coupled response from 30 kHz to 55 kHz, all
data formats
• If the IR singal strength is less then 300 mW/m2
(distance more than 0.6 m with a typical IR
remote control), the frequency range is up to
60 kHz
• Improved shielding against electrical field
disturbance
• AGC to suppress ambient noise
• High sensitivity, long receiving range
• Supply voltage: 2.5 V to 5.5 V
• Carrier out signal for IR repeater applications
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
DESCRIPTION
The TSMP1138 is a miniaturized sensor for receiving the
modulated signal of infrared remote control systems. A PIN
diode and preamplifier are assembled on a lead frame, the
epoxy package is designed as an IR filter. The modulated
output signal, carrier out, can be used for repeater
applications and code learning applications.
This component has not been qualified according to
automotive specifications.
