TSOP33233 Application Field and Working Principle

Optical Sensors – Photo Detectors – Remote Receiver

The TSOP33233 is a type of self-contained optical sensor specifically designed for infrared remote control systems. It utilizes Advanced Intellicon and multiple signal suppression circuitry, giving it an excellent signal-to-noise ratio for superior performance. Because of its advanced design it is well suited for remote control application fields such as TV, DVD, VCR, STB, etc.

The working principle of the TSOP33233 is based on transmitting a continuous infrared signal from a remote control transmitter. This infrared signal is modulated and detected by the sensor. Usually, this signal is encoded with a specific code, such as a time division multiplexed (TDM) code, to ensure unique understanding between the remote control and the appliances. When the signal from the remote control is modulated with the correct code, the TSOP33233 sensor will then generate an output, which is then translated into control signals by a microcontroller or similar type of control system.

The TSOP33233 uses a sturdy ceramic package with an integral lens, which can detect infrared signals within a specific range of angles and distances. This high degree of sensitivity provides wide area coverage, with only one receiver. Moreover, the TSOP33233 uses a three layer insulation structure, which further enhances its signal sensitivity by improving noise rejection and eliminating any parasitic effects.

The TSOP33233 is usually a surface mount device (SMD) and can be easily soldered onto a printed circuit board. It has an operating temperature range of -20 to +85 oC and an operating current range of 4 to 18 mA. The pinout of the device is 34-TS – 0-GP1 – 40-Vss – 1-OUT – 36-Vcc.

In conclusion, the TSOP33233 is a highly advanced optical sensor that is designed for remote control systems. It utilizes a unique Advanced Intellicon and multiple signal suppression circuitry to give it superior performance. Its ceramic design provides wide area coverage, with a high degree of sensitivity, while its three layer insulation structure eliminates parasitic effects and enhances the signal quality of its output. Overall, the TSOP33233 is an ideal solution for any remote control-related application.
