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.
