3 Description
The OPT101 is a monolithic photodiode with on-chip
transimpedance amplifier. 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 as a
result of stray capacitance. Output voltage increases
linearly with light intensity. The amplifier is designed
for single or dual power-supply operation.
The 0.09 inch × 0.09 inch (2.29 mm × 2.29 mm)
photodiode operates in the photoconductive mode for
excellent linearity and low dark current.
The OPT101 operates from 2.7 V to 36 V supplies
and quiescent current is only 120 μA. This device is
available in clear plastic 8-pin PDIP, and J-lead SOP
for surface mounting. The temperature range is 0°C
to 70°C.
