DESCRIPTION
The OPT101 is a monolithic photodiode with on-chip
transimpedance amplifier. Output voltage increases linearly
with light intensity. The amplifier is designed for single or
dual power-supply operation, making it ideal for battery-
operated equipment.
The integrated combination of photodiode and
transimpedance amplifier on a single chip eliminates the
problems commonly encountered in discrete designs such as
leakage current errors, noise pick-up, and gain peaking due
to stray capacitance. The 0.09 x 0.09 inch photodiode is
operated in the photoconductive mode for excellent linearity
and low dark current.
The OPT101 operates from +2.7V to +36V supplies and
quiescent current is only 120
A. It is available in clear
plastic 8-pin DIP, and J-formed DIP for surface mounting.
Temperature range is 0
C to +70
C.

MOISTURE SENSITIVITY
AND SOLDERING
Clear plastic does not contain the structural-enhancing fillers
used in black plastic molding compound. As a result, clear
plastic is more sensitive to environmental stress than black
plastic. This can cause difficulties if devices have been stored
in high humidity prior to soldering. The rapid heating during
soldering can stress wire bonds and cause failures. Prior to
soldering, it is recommended that plastic devices be baked-out
at +85
C for 24 hours.
The fire-retardant fillers used in black plastic are not compat-
ible with clear molding compound. The OPT101 plastic
packages cannot meet flammability test, UL-94.

NOTE: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may degrade
device reliability. These are stress ratings only, and functional operation of the
device at these or any other conditions beyond those specified is not implied.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be handled
with appropriate precautions. Failure to observe proper han-
dling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
