TSOP946..中文资料威世数据手册PDF规格书

DESCRIPTION

The TSOP94... 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 TSOP946.., series devices are designed to receive long

burst codes (10 or more carrier cycles per burst). The third

digit designates the AGC level (AGC6) 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. AGC6 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.
