TSOP34338 Integrated IR receiver; 38kHz; 90°; 2.5÷5.5V

The TSOP34338 is a compact and highly sensitive infrared receiver module designed for remote control applications. Operating at a carrier frequency of 38kHz, this receiver is compatible with a wide variety of standard IR remote controls. Its operating voltage range of 2.5V to 5.5V provides versatility for integration into various electronic devices. The wide acceptance angle of 90 degrees ensures reliable signal reception, even when the remote control is not precisely aligned with the receiver. This integrated module simplifies the design process by incorporating the photodiode, preamplifier, and demodulation circuitry into a single, easy-to-use package.

This IR receiver is ideally suited for use in consumer electronics such as televisions, set-top boxes, audio equipment, and home automation systems. Its small size and ease of integration make it a perfect choice for both new designs and replacements in existing products. The TSOP34338 offers excellent immunity to noise and ambient light, minimizing the risk of false triggering and ensuring reliable operation in various environments. Its low power consumption makes it suitable for battery-powered devices, extending battery life and reducing energy costs.

Key features of the TSOP34338 include a high-gain photodiode, a low-noise amplifier, and an internal filter that effectively suppresses unwanted signals. The demodulator extracts the control signal from the modulated IR carrier, providing a clean and stable output signal for connection to a microcontroller or other control logic. The automatic gain control (AGC) feature automatically adjusts the receiver's sensitivity to compensate for variations in signal strength, ensuring consistent performance over a wide range of distances. This integrated module reduces component count and simplifies PCB layout, saving both time and cost.

When incorporating the TSOP34338 into a system, careful consideration should be given to the placement of the receiver to minimize interference from other IR sources. Shielding the receiver from direct sunlight and other strong IR emitters can significantly improve performance. The output signal from the receiver can be directly connected to a microcontroller's input pin for decoding the remote control commands. The TSOP34338 is a reliable and cost-effective solution for adding remote control functionality to a wide range of electronic devices. Its robust design and ease of use make it a popular choice among engineers and hobbyists.
