MECHNICAL DATA
Pinning for TSOP44.., TSOP48..:

DESCRIPTION

1 = OUT, 2 = GND, 3 = VS

The TSOP22.., TSOP48.., TSOP24.. and TSOP44.. series

are miniaturized IR receiver modules for infrared remote
control systems. A PIN diode and a preamplifier are
assembled on lead frame, the epoxy package contains an IR
filter.

Pinning for TSOP22.., TSOP24..:

1 = OUT, 2 = VS, 3 = GND

The demodulated output signal can be directly connected to

a microprocessor for decoding.
The TSOP24.., TSOP44.. are optimized to suppress almost
all spurious pulses from energy saving lamps like CFLs. The
AGC4 used in the TSOP24.. and TSOP44.. may suppress
some data signals. The TSOP22.., TSOP48.. are legacy
products for all common IR remote control data formats.
Between these four receiver types, the TSOP24.., TSOP44..
are preferred. Customers should initially try the TSOP24..,
TSOP44 in their design.
These components have not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT

IR Signal

This 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 devices band-pass center
frequency (e.g. 38 kHz) and fulfill the conditions in the table
below.
When a data signal is applied to the product 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 receivers output. Some
examples which are suppressed are:

DC light (e.g. from tungsten bulbs sunlight)
