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 de-
signs 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, 5-pin SIP and J-formed DIP for
surface mounting. Temperature range is 0
C to 70
C.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with ap-
propriate precautions. Failure to observe proper handling 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.
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.
