OPT101 LIGHT INTENSITY SENSOR ANALOGUE

<p><strong><span style=”font-size:18px;”><span style=”font-family:Arial,Helvetica,sans-serif;”>Description</span></span></strong></p>

<p><span style=”font-size:14px;”><span style=”font-family:Arial,Helvetica,sans-serif;”>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 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.&nbsp;</span></span></p>

<p><span style=”font-size:14px;”><span style=”font-family:Arial,Helvetica,sans-serif;”>The photodiode has a very large measurement area that collects a significant amount of light, and thus allows for high-sensitivity measurements. Output voltage increases linearly with light intensity. The on-chip voltage source keeps the amplifier in a good operating region, even at low light levels.</span></span></p>

<p><span style=”font-size:14px;”><span style=”font-family:Arial,Helvetica,sans-serif;”>The wide power-supply range of 2.7 V to 36 V makes this device useful in a variety of architectures; from all-analog circuits to data conversion base circuits. 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.&nbsp;</span></span></p>
