DESCRIPTION
The OPT201 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 OPT201 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, specified
for the 0°C to 70°C temperature range.
