SS6863

SS6863 IR Preamplifier for Remote Control Systems FEATURES Only two external components required other than the photodiode. Easy to integrate into modules due to its small package size. Minimal chance of malfunction due to ambient light. Low power consumption. Band-pass filter center frequency set using an external resistor Microcomputer compatible. DESCRIPTION T he SS6863 is a high-performance infra-red remote-control pre-amplifier, offering excellent interference-suppression capability. The infra-red pulses received by the photo-diode are processed by the trans-impedance amplifier and amplified by the AGC amplifier, limiter amplifier and band-pass filter. The evaluation stages that follow, including the comparator, Integrator and schmitttrigger, demodulate the transmitted digital signal. Reduced sensitivity to external interference is acheived by using short-term boost and longterm control circuits to prevent Interference from affecting the output. APPLICATIONS IR remote control receivers for consumer electronic products, such as TVs, VCRs, VCD/DVD players, audio devices, electric fans, air-conditioners, etc. TYPICAL APPLICATION CIRCUIT Vcc (+5V) 1 CA 2 NC C1 0 .1µF VOUT 3 OUT 4 DGND VCC 8 FO 7 R1 110kΩ (fo=38kHz) AGND 6 IN 5 SS6863 Photo Diode IR Remote Control Receiver Rev.2.02 11/6/2003 www.SiliconStandard.com 1 of 6 SS6863 ORDERING INFORMATION S S6863CXXX Packing TR: Tape and reel PIN CONFIGURATION S O-8 CA 1 TOP VIEW 8 7 6 5 VCC FO A GND IN Package type S: SO-8 NC 2 OUT 3 DGND 4 Example: SS6863CSTR $ i n SO-8 package supplied on tape and reel ABSOLUTE MAXIMUM RATINGS Supply Voltage Input Voltage ......................................................................................... ............ 5.5V ...................................................................................................... 5V P-P Operating Temperature Range ....................................................................... -20°C ~ 80°C Storage Temperature Range ........................................................................... -65°C ~ 150°C TEST CIRCUIT Vcc (+5V) 1 CA + C1 VOUT 3 OUT 0.1µF 4 DGND SS6863 VCC FO AGND 8 7 6 R1 110K 2 NC IN 5 S5 C3 + 0.47µF S4 S3 R2 47K + C2 S2 IIN 100µA 0.47µF S1 VIN Rev.2.02 11/6/2003 www.SiliconStandard.com 2 of 6 SS6863 ELECTRICAL CHARACTERISTICS (VCC = 5V, TA = 25 °C unless otherwise specified) ° PARAMETER , ,8.9 ,849 &&*
