TSOP32340

The TSOP32340 is a Remote Receiver, a type of photo detector within the wider category of Optical Sensors. Specifically, this device can detect remote controls and decode the digital signal from their Infra-red (IR) emitters. These types of sensors are commonplace in consumer electronics, allowing for a no-contact control solution from a handheld device.

The TSOP32340 is a particularly useful device due to its wide dynamic range and built-in noise suppression. It has been optimised to receive the 34khz carrier frequency modulated IR signal typically found in most consumer electronics. This level of specificity to the application field makes the device ideal for use in a wide variety of consumer electronics products.

The working principle of the TSOP32340 is quite simple. It consists of a semi-conductive material such as gallium arsenide or gallium phosphide, which is in turn sandwiched between a pair of photocells. When the modulated IR carrier frequency is emitted from the remote controller, it is detected by the pair of photocells. In turn, one of the photocells is illuminated or not, depending on the modulation type. This change in illumination between the two photocells is then converted into a digital signal by the device.

On the signal conversion side, the TSOP32340 has a built in amplifier and a signal conditioning circuit. This allows the received signal to receive additional filtering and amplification before it is output as a digital signal for further processing. In addition, the device also features programmable active mode and standby currents to facilitate power saving when not detecting an IR signal.

Overall, the TSOP32340 is a versatile and highly efficient Remote Receiver. Its built-in features allow for easy integration into existing consumer electronic designs, making it an ideal choice for a wide range of applications.
