UPC2800A中文资料PREAMPLIFIER FOR INFRARED REMOTE CONTROL数据手册Renesas规格书

描述 Description

The µPC2800A is a receiver preamplifier for infrared remote control systems. It can be directly connected to a PIN photodiode and integrates a high-gain first-stage amplifier, limiter, bandpass filter, detection circuit, and waveform shaping circuit to provide a receiver preamplifier on a single chip.UPC2800AGR 8-pin plastic SOP (225 mil)

FEATURES
• High reliability due to high-frequency lighting fluorescent lamp Internal trap circuit
• Internal bandpass filter Central frequency variable by external resistor: fO= 30 to 80 kHz Few variation of central frequency thanks to fOtrimming
• Low external components
