The OPT101 is a monolithic photodiode with op-chip transimpidance amplifier. The integrated combination of the photodiode and transimpidance amplifier on a single chip eliminates the problems commonly encountered in discrete designs, such as leakage current errors, noise pickup, and gain peaking as result of stray capacitance. Output voltage increases linearly with light intensity. The power amplifier works on single supply. The 2.29mm X 2.29 mm photodiode operates in the photoconductive mode for excellent linearity and low dark current.
The OPT101 is a large-area photodiode integrated with an optimized operational amplifier that makes the OPT101 a small, easy-to-use, light-to-voltage device. The photodiode has a very large measurement area that collects a significant amount of light, and thus allows for high-sensitivity measurements. The photodiode has a wide spectral response with a maximum peak in the infrared spectrum, and a useable range from 300 nm to 1100 nm. from all-analog circuits to data conversion base circuits. The on-chip voltage source keeps the amplifier in a good operating region, even at low light levels. The OPT101 voltage output is the product of the photodiode current times the feedback resistor, (IDRF), plus a pedestal voltage, VB, of approximately 7.5 mV introduced for single-supply operation. Output is 7.5 mV dc with no light, and increases with increasing illumination. Photodiode current, ID, is proportional to the radiant power, or flux, (in watts) falling on the photodiode. At a wavelength of 650 nm (visible red) the photodiode responsively, RI, is approximately 0.45 A/W. Responsively at other wavelengths is shown in Figure 1. The internal feedback
