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 TSOP982. and TSOP984. series devices are designed to receive long burst codes (10 or more carrier cycles per burst).
The third digit designates the AGC level (AGC2 or AGC4) 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. AGC2 provides basic noise …
