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.
