DESCRIPTION
The TSOP98... series devices are the latest generation miniaturized IR receiver modules for infrared remote control systems. This series provides improvements in sensitivity to remote control signals in dark ambient as well as in sensitivity in the presence of optical disturbances e.g. from CFLs.
The devices contain a PIN diode and a preamplifier assembled on a lead frame. The epoxy package contains an IR filter. The demodulated output signal can be directly connected to a microprocessor for decoding.
The TSOP983.. and TSOP985.. series devices are designed to receive short burst codes (6 or more carrier cycles per burst). The third digit designates the AGC level (AGC3 or AGC5) and the last two digits designate the band-pass frequency (see table below). The higher the AGC, the better noise is suppressed, but the lower the code compatibility. AGC3 provides enhanced noise suppression and AGC5 provides maximized noise suppr.
