IR Preamplifier for Remote Control System

Product Specification DF0038B IR Preamplifier for Remote Control System w w w .d e e h s a t a . u t4 m o c No: TDSPEC2006E Date: 2002.10. www.DataSheet4U.com Tide Microelectronics DF0038B IR Preamplifier for Remote Control System GENERAL DESCRIPTION The DF0038B is a high performance infrared remote control preamplifier. Especially, it has excellent interference suppression capability. The infrared pulses arriving at the photodiode are treated by the trans-impedance amplifier and amplified by the auto-gain control amplifier, limiter amplifier, and band-pass filter. The following evaluation circuits, including the comparator, integrator, and schmitt-trigger, demodulate the transmitted digital signal. Reduction of sensitivity due to external interference is achieved by the short-time boost and long-time control circuits, which prevent interference voltages from affecting the output. FEATURES Only Two External Components Required Other than the Photodiode. Easy to Integrate into Module due to Small Chip Size. Minimized Chances of Malfunction Due to Ambient Light. Low Power Consumption. Center Frequency of Band Pass Filter Adjustable by an External Resistor. Microcomputer Compatible. APPLICATIONS IR Remote Control Receivers for Consumer Electronic Products, such as TVs, VCRs, VCD/DVD Players, Audio Devices, Air Conditioners, Electric Fans...etc. PIN CONFIGURATONS PIN DESCRIPTIONS PIN 1: GND PIN 2: Vs PIN 3: OUT Ground. Power supply pin. Output pin. 2 of 2.
