Additional Details

The TSOP2838 operates with a supply voltage range of 2.5 V to 5.5 V. The output is an active-low signal, meaning that the output is low when an IR signal is detected. The internal filter effectively suppresses noise and unwanted IR signals, enhancing the reliability of the remote control system.

This device is a through-hole component, making it easy to mount on PCBs. The TSOP2838 is RoHS compliant.
