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 400mA. 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.
