The upgrade of the TFBS4xx and TFDU4xx series consists of a photodetector, a preamplifier circuit, and an IR filter in a single housing, which is offered in different sizes as a "top-view" or "side-view" housing for surface mounting. The improved solutions enable a plug-and-play replacement for existing components in the series.
With these IR transceiver modules, customers benefit from the long-term availability of IRDC products. The drop-in technology also saves costs, as a new PCB design is obsolete. The modules impress with their very low power consumption with a quiescent current of < 70 μA and thus extend the service life of batteries in portable devices. They work in an operating voltage range of 2.4 V to 5.5 V at an operating temperature of -25 °C to +85 °C.
The components comply with the latest IrDA® specification for the physical layer, are backwards compatible, and are available in a wide range of housing sizes.
