Vishay has introduced a new series of infrared (IR) receiver modules for IR remote control applications. Featuring a wide modulation frequency acceptance from 30 kHz to 68 kHz, the devices in the TSOP15300 series are designed to receive and demodulate all major remote control codes on the market, enabling a single-component universal remote control solution.
Standard IR receivers are typically tuned to one center frequency, limiting compatibility and requiring multiple devices to cover different code sets. With their wide modulation frequency range, the receivers released today overcome this limitation, reducing component counts to lower system costs and saving board space.
Designed for a wide range of consumer electronics and more, the TSOP15300 series receivers provide immunity against ripple noise and interference from common sources like IR emissions in CFL lamps and LCD televisions, and RF emissions from onboard Wi-Fi antennas. When paired with a 50 mA emitter, the devices offer reliable transmission distances of up to 18 m.
To simplify designs, each receiver integrates a photodetector, preamplifier circuit, and IR filter within a 4-pin Heimdall package. For decoding, their demodulated output signal can be directly connected to a microprocessor. Optimised for short burst codes, TSOP15300 series devices operate over a wide supply voltage range from 2,0 V to 5,5 V, draw a typical supply current of 0,35 mA, and feature a maximum irradiance of 0,2 mW/m2 at 45 kHz. They are RoHS-compliant, halogen-free, and Vishay Green.
