DESCRIPTION
The OPT101 is a monolithic photodiode with on-chip
transimpedance amplifier. Output voltage increases
linearly with light intensity. The amplifier is designed
for single or dual power supply operation, making it
ideal for battery operated equipment.
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 0.09 x 0.09
inch photodiode is operated in the photoconductive
mode for excellent linearity and low dark current.
The OPT101 operates from +2.7V to +36V supplies
and quiescent current is only 120µA. It is available in
clear plastic 8-pin DIP, 5-pin SIP and J-formed DIP for
surface mounting. Temperature range is 0°C to 70°C.
