Linear array optocoupler HCNR series

Avago's linear transducer is a high linearity analog optocoupler which consists of a high performance AlGaAs LED that illuminates two closely matched photodiodes. The close matching of the photodiodes and advanced design of the package ensure the high linearity and stable gain of the optocoupler. These linear transducer optocouplers can be used in applications where high bandwidth, low-cost, and stable gain are required such as feedback path of switched mode power supplies, motor speed and position measurement, and analog voltage sensor.
