DESCRIPTION

The TSOP99... series devices are the latest generation

miniaturized IR receiver modules for infrared remote control

systems. These series provide 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 TSOP992.. and TSOP994.., 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 suppression and AGC4 provides

enhanced 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.
