TSOP934..DF1P中文资料威世科技数据手册PDF规格书

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 TSOP932..DF1P and TSOP934..DF1P, 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.
