TSOP32238 Integrated IR receiver; 38kHz; 90°; 2.5÷5.5V

The TSOP32238 is a miniature infrared receiver module for remote control systems. This component is designed to receive infrared signals modulated at a carrier frequency of 38kHz, making it compatible with a wide range of standard IR remote controls. It operates within a supply voltage range of 2.5V to 5.5V, offering flexibility in various electronic applications. The receiver has a wide acceptance angle of 90 degrees, ensuring reliable signal reception even when the remote control is not pointed directly at the receiver. This integrated IR receiver simplifies the design of remote control systems by incorporating the photodiode, preamplifier, and demodulating circuit in a single package.

This IR receiver is ideal for use in televisions, DVD players, set-top boxes, and other consumer electronics that require remote control functionality. Its compact size and ease of use make it suitable for both new designs and replacements in existing systems. The TSOP32238 offers excellent noise immunity, preventing false triggering from ambient light and other sources of interference. This ensures reliable operation even in challenging environments. The device is also designed to be energy-efficient, consuming minimal power during operation, which is crucial for battery-powered devices.

The TSOP32238's key features include a high sensitivity photodiode, a low-noise preamplifier, and an internal filter for suppressing unwanted signals. The demodulator extracts the control signal from the modulated IR carrier, providing a clean output signal for the microcontroller or other control circuitry. The automatic gain control (AGC) feature compensates for variations in signal strength, ensuring consistent performance over a wide range of distances. This integrated module reduces the component count and simplifies the PCB layout, saving both space and cost.

When integrating the TSOP32238 into a system, it is important to consider the placement of the receiver to minimize interference from other IR sources. Shielding the receiver from direct sunlight and other strong IR emitters can 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 TSOP32238 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 alike.
