SS6863
IR Preamplifier for Remote Control Systems
FEATURES
DESCRIPTION
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.
The 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 long-
