用Ｌｉｎｅａｒ Ｔｅｃｈｎｏｌｏｙｙ公司的 ＬＴ１３２８ ＩｒＤＡ接收器可构成简单、廉价的ＩｒＤＡ接收电路。ＬＴ１３２８包含从外部光电二极变换电流脉冲到数字ＴＴＬ输出所必需的全部电路，并可抑制不希望的低频干扰。 ＬＴ１３２８加 ５个外部元件就可构成一个ＩｒＤＡ
The LT1328 IrDA receiver from Linear Technoloyy forms a simple, inexpensive IrDA receiver circuit. The LT1328 contains all the circuitry necessary to convert current pulses from an external photodiode to a digital TTL output and suppress unwanted low frequency interference. LT1328 plus five external components can form an IrDA
