U2538B中文资料IR Receiver for Data Communication数据手册Microchip规格书

描述 Description

The IC U2538B is a complete IR receiver for data communication. The useful input signals are  separated by a special input circuit and amplified by a gain-controlled amplifier. The bandpass filter suppresses the off-band signals. The signal detector, consisting of a demodulator, an integrator and a Schmitt trigger, forms the input signal to an output pulse that can be interfaced to a microcomputer. The AGC and the ATC circuit control the receiver's sensitivity, making it insensitive to ambient light sources.

特性 Features

• Few External Components
• Low Power Consumption
• Microcomputer Compatible
• Insensitive to Ambient Light and Other Continuous Interferences
