Description
The TFMS 5..0 – series are miniaturized receivers for in-
frared remote control systems. PIN diode and
GND
preamplifier are assembled on lead frame, the epoxy
V_S
OUT
package is designed as IR filter.
The demodulated output signal can directly be decoded
94 8691
by a microprocessor. The main benefit is the reliable
function even in disturbed ambient and the protection
against uncontrolled output pulses.
