DESCRIPTION
The TSOP57... series are miniaturized SMD IR receiver
modules for infrared remote control systems. A PIN diode
and a preamplifier are assembled on a PCB, the epoxy
package contains an IR filter.
The demodulated output signal can be directly connected to
a microprocessor for decoding.
The TSOP574.. series devices are optimized to suppress
almost all spurious pulses from Wi-Fi and CFL sources.
They may suppress some data signals if continuously
transmitted.
The TSOP572.. series devices are provided primarily for
compatibility with old AGC2 designs. New designs should
prefer the TSOP574.. series containing the newer AGC4.
These components have not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT
The TSOP572.., TSOP574.. series is designed to suppress
spurious output pulses due to noise or disturbance signals.
The devices can distinguish data signals from noise due to
differences in frequency, burst length, and envelope duty
cycle. The data signal should be close to the device’s
band-pass center frequency (e.g. 38 kHz) and fulfill the
conditions in the table below.
When a data signal is applied to the TSOP572.., TSOP574..
in the presence of a disturbance, the sensitivity of the
receiver is automatically reduced by the AGC to insure that
no spurious pulses are present at the receiver’s output.
Some examples which are suppressed are:
• DC light (e.g. from tungsten bulbs sunlight)
• Continuous signals at any frequency
• Strongly or weakly modulated patterns from fluorescent
lamps with electronic ballasts (see fig. 13 or fig. 14)
• 2.4 GHz and 5 GHz Wi-Fi
