-[[http://www.analog.com/CN0272|CN-0272]] is a high-speed photodiode signal conditioning circuit with dark current compensation. The system converts current from a high-speed silicon PIN photodiode and drives the inputs of a 20 MSPS ADC. This combination of parts offers spectral sensitivity from 400 nm to 1050 nm with 49 nA of photocurrent sensitivity, a dynamic range of 91 dB and 2 MHz of bandwidth. The signal conditioning circuitry of the system consumes only 40 mA of current from the ±5 V supplies making this configuration suitable for portable high-speed high-resolution light intensity applications such as pulse oximetry.+[[adi>CN0272|CN-0272]] is a high-speed photodiode signal conditioning circuit with dark current compensation.

 Other suitable applications for this circuit would be as an analog opto-isolator. It can also be adapted to applications that require larger bandwidth and less resolution such as adaptive speed control systems.  Other suitable applications for this circuit would be as an analog opto-isolator.
