Vishay Intertechnology’s TSOP15300 series infrared (IR) receiver modules for IR remote control applications receive and demodulate all major remote-control codes on the market. The devices specify a modulation-frequency acceptance from 30 kHz to 68 kHz, thereby enabling single-component universal remote-control designs.
The receivers also provide immunity against ripple and interference from common sources like IR emissions in CFL lamps and LCD televisions, and RF emissions from onboard Wi-Fi antennas. Working with a 50-mA emitter, the devices work reliably at transmission distances up to 18 meters.
Each receiver integrates a photodetector, preamplifier circuit, and IR filter within a 4-pin Heimdall package. For decoding, demodulated output signals can directly connect to a microprocessor. Optimized for short burst codes, the devices operate over a supply voltage range from 2V to 5.5V, draw a typical supply current of 0.35 mA, and feature a maximum irradiance of 0.2 mW/m² at 45 kHz.
Samples and production quantities are available now, with lead times of six weeks. For greater enlightenment, procure and peruse the TSOP15300 series datasheet.
