DESCRIPTION

The OPT301 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 OPT301 operates over a wide supply range (±2.25
to ±18V) and supply current is only 400µA. It is
packaged in a hermetic TO-99 metal package with a
glass window, and is specified for the –40°C to 85°C
temperature range.

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.
