DESCRIPTION
The TSOP93... 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 TSOP931.., TSOP933.., and TSOP935.., series devices
are designed to receive short burst codes (6 or more carrier
cycles per burst). The third digit designates the AGC level
(AGC1, 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
