Optical Sensors
Analog Devices optical sensors are optical sensing front ends that include integrated ultra-low noise amplification and high performance photodiodes. These solutions are used to achieve the highest performance for instrumentation, industrial, or clinical applications; or to optimize a solution to achieve the lowest power dissipation at a given performance level for battery powered and portable applications.
