DESIGN SUPPORT TOOLS click logo to get started DESCRIPTION

These products are miniaturized IR receiver modules for
Models infrared remote control systems. A PIN diode and a
Available
preamplifier are assembled on a leadframe, the epoxy
package contains an IR filter.
MECHANICAL DATA
The demodulated output signal can be directly connected to
Pinning for TSOP382.., TSOP384..: a microprocessor for decoding.
1 = OUT, 2 = GND, 3 = VS The TSOP384.. series devices are optimized to suppress
almost all spurious pulses from energy saving lamps like
CFLs. The AGC4 used in the TSOP384.. may suppress
some data signals. The TSOP382.. series are provided
primarily for compatibility with old AGC2 designs. New
designs should prefer the TSOP384.. series containing the
newer AGC4.
These components have not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT Axis Title
This series is designed to suppress spurious output pulses 7 10000
due to noise or disturbance signals. The devices can
6
distinguish data signals from noise due to differences in
frequency, burst length, and envelope duty cycle. The data 5

When a data signal is applied to the product in the
presence of a disturbance, the sensitivity of the receiver is 100

automatically reduced by the AGC to insure that no spurious
pulses are present at the receiver’s output. 1
Some examples which are suppressed are:
