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 (鹵2.25
to
鹵18V)
and supply current is only 400碌A(chǔ). It is
packaged in a transparent plastic 8-pin DIP or 5-pin
SIP, specified for the 0擄C to +70擄C temperature range
as well as a hermetic ceramic 8-pin DIP with a glass
window, specified for the 鈥?0擄C to +85擄C tempera-
ture range.
