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 designs 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, and J-formed DIP for surface mounting.
Temperature range is 0°C to +70°C.
APPLICATIONS
● MEDICAL INSTRUMENTATION
● LABORATORY INSTRUMENTATION
● POSITION AND PROXIMITY SENSORS
● PHOTOGRAPHIC ANALYZERS
● BARCODE SCANNERS
● SMOKE DETECTORS
● CURRENCY CHANGERS
