DESCRIPTION
The OPT202 is an opto-electronic integrated circuit containing a photodiode and transimpedance amplifier on a single dielectrically isolated chip. The transimpedance amplifier consists of a precision FETinput op amp and an on-chip metal film resistor. The 0.09 x 0.09 inch photodiode is operated at zero bias for excellent linearity and low dark current.
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 OPT202 operates over a wide supply range (±2.25 to ±18V) and supply current is only 400μA. It is
packaged in a transparent plastic 8-pin DIP or 5-pin SIP, specified for the 0°C to +70°C temperature range
as well as a hermetic ceramic 8-pin DIP with a glass window, specified for the –40°C to +85°C tempera-
ture range.

ELECTROSTATIC DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate 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 compatible with clear molding compound. The OPT202 plastic packages cannot meet flammability test, UL-94.
