DESCRIPTION
The OPT211 is a monolithic photodiode with on-chip
FET-input transpedance amplifier, that provides wide
bandwidth at very high gains. Uncommitted input and
feedback nodes allow a variety of feedback options for
maximum versatility. Trade-offs in responsivity (gain),
bandwidth and SNR can easily be made.
The monolithic 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 pickup and
gain peaking due to stray capacitance. The 0.09 x 0.09
inch photodiode is operated at zero bias for excellent
linearity and low dark current. Direct access to the
detector’s anode allows photodiode bootstrapping,
which increases speed performance.
The OPT211 operates over a wide supply range (±2.25V
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.
