DESCRIPTION

The TSOP93...DF1P 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..DF1P, TSOP933..DF1P, and

TSOP935..DF1P, 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.
