OPT301 pdf datasheet (INTEGRAT

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.
