DESCRIPTION
16833-13
The TSOP33...DF1P 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.

AGC
The TSOP333..DF1P series devices are optimized to
suppress almost all spurious pulses from energy saving
lamps like CFLs. AGC3 may also suppress some data
signals if continuously transmitted.

Control circuit
The TSOP331..DF1P series are provided primarily for
compatibility with old AGC1 designs. New designs should
prefer the TSOP333..DF1P series containing the newer
AGC3. The TSOP335..DF1P series contain a very robust
AGC5. This series should only be used for critically noisy
environments.
