DESCRIPTION
The OPT210 is a photodetector consisting of a high
performance silicon photodiode and precision FET-
input transimpedance amplifier integrated on a single
monolithic chip. Output is an analog voltage propor-
tional to light intensity.
The large 0.09" x 0.09" photodiode is operated at low
bias voltage for low dark current and excellent linear-
ity. A novel photodiode anode bootstrap circuit re-
duces the effects of photodiode capacitance to extend
bandwidth and reduces noise.
The integrated combination of photodiode and
transimpedance amplifier on a single chip eliminates
the problems commonly encountered with discrete
designs such as leakage current errors, noise pick-up
and gain peaking due to stray capacitance.
The OPT210 operates from
±
2.25 to
±
18V supplies
and quiescent current is only 2mA. Available in a
transparent 8-pin DIP, 8-lead surface-mount and 5-pin
SIP, it is specified for 0
°
to 70
°
C operation.
