The TSOP11..RF1 series are miniaturized receivers for infrared remote control systems. They consist of PIN diode and preamplifier assembled on lead frame, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor.
The TSOP11..RF1 series provides a compact infrared receiver that integrates a photodiode and preamplifier in a lead‑frame package with an epoxy IR filter. It delivers an active‑low TTL/CMOS output that can be directly decoded by a microprocessor and supports short‑burst transmission codes and high data rates.
The device is offered for several carrier frequencies (30 kHz to 56 kHz) and includes features such as low power consumption, high immunity to ambient light, and built‑in automatic gain control. Absolute maximum ratings, typical characteristics, and detailed optical test results are provided for design verification. This manual is written in Chinese.
