The SHARP GP2W0001YP/GP2W0002YP infrared transceiver modules contain a high speed, high efficiency, low power consumption AlGaAs LED, silicon PIN photodiode, and a low power bipolar integrated circuit. The IC contains an LED driver circuit and a receiver, providing the Rx output. IrDA data rates of 2.4 Kbps to 115.2 Kbps are supported at both 20 cm and one-meter distances. At the one-meter range, emitter current is approximately IF = 300 mA and in the IrDA Low Power Option communication mode IF = 27 mA. This dual mode communication capability provides wider product applications, such as a wireless data link with PCs, PDAs, or any other IrDA compliant application already on the market.
