Atmel has released a low-voltage IR (InfraRed) receiver IC for remote-control receiver applications such as TV, VCR, satellite receivers, mobile cameras, audio devices, wireless devices etc. The T2527's low-voltage feature makes it well suited for all kinds of battery-driven devices, especially those operating at 3 V. This device offers an extended transmission range.
The supply voltage range is optimised for 2,7 to 3,6 V to support 3 V products and this also results in low current consumption (<1 mA), which is 25% less than at 5 V. Due to the outstanding sensitivity performance (less than 1 nA), along with the connected PIN diode and the device's small bandwidth (±1,25%), the T2527 provides extended transmission distance with less tolerances than most conventional products, even in a dark environment when using a standard remote-control transmitter, according to the manufacturer.
The T2527 is highly integrated; to design a complete reception unit (either module or discrete solution), only a high-performance IR-receiving diode (normally a PIN diode) has to be connected to the IC. No further external parts are required. A further benefit is its high noise and disturbance suppression. A special regulation algorithm is used for noise suppression from daylight or sunlight, as well as from energy-saving lamps, inverter-lamps and fluorescent lamps.
The T2527 is available with various carrier frequencies (30, 33, 36, 38, 40, 44, 56 and 78 kHz) and in 3 regulation versions. The standard version works with almost all transmission protocols used worldwide. The lamp-version ICs provide improved disturbance suppression, and the short-burst version is especially designed for applications with high data rates and short bursts.
