TSOP985..中文资料威世科技数据手册PDF规格书

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 suppression. Generally, we

advise to select the highest AGC that satisfactorily receives

the desired remote code.

These components have not been qualified to automotive

specifications.
