Analog optocoupler ic

Broadcom HCNR2high-linearity analog optocoupler can be used to isolate analog signals in applications that require good stability, linearity, bandwidth and low cost. ISOamps typically employ transformers and high-voltage capacitors or optocouplers in the isolation barrier design. The example below is from Analog Devices AN-106.


An optocoupler is used to transmit either analog or digital information from one voltage potential to another while maintaining isolation of the potentials of less than 0V. The optoisolator is designed to isolate power systems while transmitting analog or digital data between the systems with isolation .

The interfacing of the optocoupler between digital or analogue signals needs to be designed correctly for proper protection.

The following examples help in this area by using DC- and AC-input phototransistor optocouplers.

OPTOCOUPLERS IN IC LOGIC DESIGN. To interface with TTL logic circuits, Vishay . Optocouplers are slow, power hungry, difficult to integrate with other functions and degrade over time. By contrast, iCoupler digital isolators offer an alternative to optocouplers by combining high bandwidth on-chip transformers and fine scale CMOS circuitry that improve reliability, size, . Industrial Process Control: Transducer Isolator.


Implement isolated analog signals and current loops with linear optocouplers. To achieve linearity, with Rat 80kO, the input voltage, VIN will need to be maximum of 4V and keeping the maximum photodiode current at 50µA (as specified in the datasheet ). The linear transfer function for this application . It is ideal for video isolation when combined with its application curcuit. High speed CMOS, combined with monolithic air core transformer technology, means the on-chip isolation provides outstanding performance characteristics, superior to alternatives such as optocoupler devices. The device contains an on- chip reference. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives, such as .
