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 120 A. 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 INFORMATION Figure 1 shows the basic connections required to operate the OPT101. Applications with high-impedance power supplies may require decoupling capacitors located close to the device pins as shown. Output is 7.5mV dc with no light and increases with ...

DARK ERRORS The dark errors in the specification table include all sources. The dominant source of dark output voltage is the “pedestal” voltage applied to the non-inverting input of the op amp. This voltage is introduced to provide linear operation ...

... An external 1M resistor used in the configuration shown in Figure 4b will create a 23kHz bandwidth with the 6 same 10 V/A dc transimpedance gain. This yields a rise time of approximately 15 s (10% to 90%). Dynamic response is not limited by op amp slew rate. This is demonstrated by the dynamic response oscilloscope photographs showing virtually identical large-signal and small-signal response ...
