The uPC1373H/HA is designed as the infrared remote control receiving preamplifier bipolar type analog circuit that can be used in the TV and video tape recorder. The internal circuit is composed of the preamplifier, the automatic bias controller (ABLC), the limiter and the level drift compensation circuit, the peak detector, the pulse shaping circuit. The uPC1373H and uPC1373HA have the different shape structure. Features Low power consumption, the typical value of Icc is 2.5mA.The input sensitivity is high, the typical value is 50uV (peak value).The power voltage range is wide, he value is 6-14.4V.The few external components.The automatic bias controller (ABLC) adjusts the gain of the amplifier automatically, and makes the input signal has the wide dynamic range.
