DESCRIPTION
The TSSP77038 is a compact two lens SMD IR receiver
for sensor applications. It has a high gain for IR signals
at 38 kHz. The detection level does not change when
ambient light or strong IR signals are applied. It can receive
continuous 38 kHz signals or 38 kHz bursts.
This component has not been qualified according to
automotive specifications.
