DESCRIPTION

The OPT210 is a photodetector consisting of a high
performance silicon photodiode and precision FET­input transimpedance amplifier integrated on a single
monolithic chip. Output is an analog voltage propor­tional to light intensity.

The large 0.09" x 0.09" photodiode is operated at low
bias voltage for low dark current and excellent linear­ity. A novel photodiode anode bootstrap circuit re­duces 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.
