VISHAY TSOP94540

The TSOP94... series devices are the latest generation of miniaturized IR receiver modules for infrared remote control systems. These series offer improvements in sensitivity to remote control signals in dark environments, as well as sensitivity in the presence of optical interference (e.g., from compact fluorescent lamps).

These devices contain a PIN diode and a preamplifier assembled on a lead frame. An infrared filter is integrated within the epoxy package. The demodulated output signal can be directly connected to a microprocessor for decoding.

The TSOP943.. and TSOP945.. series devices are designed to receive short burst codes (6 or more carrier cycles per burst). The third digit indicates the AGC level (AGC3 or AGC5), and the last two digits indicate the bandpass frequency (see table below). Higher AGC provides better noise suppression but lower code compatibility. AGC3 provides enhanced noise suppression, and AGC5 provides maximum noise suppression. In general, it is recommended to select the highest AGC that satisfactorily receives the required remote control codes.

These components are not qualified to automotive specifications.
