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 FET-

input 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 de-

signs 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.
