About Isolation

Our broad portfolio of isolation products use Chipanalog’s capacitive isolation technology based on silicon oxide (SiO2) insulation barrier that provide complete galvanic isolation between two power domains. We offer standard digital isolators, low-power digital isolators, dedicated digital isolators for smart meter and the complete digital isolators with integrated power supply; Also, we offer isolated interface products, including the isolated I2C, isolated CAN transceivers, isolated RS-422/RS-485 transceivers and the isolated transceivers with built-in low-EMI DC-DC converter, isolated octal digital input receivers etc. high-integration solutions. We also offer isolated amplifiers. With Chipanalog’s advanced capacitive isolation technology, our isolation family products feature high reliability, high electromagnetic immunity, low propagation delay and low jitter. Thousands of customers have adopted these solutions in their end applications.

Digital isolation is required to prevent conduction between two parts of a system, while still allowing signal transfer between those two parts. It is implemented to prevent current surges from damaging equipment and break ground loops where different ground potentials are involved. In many applications, digital isolators based on CMOS technology are replacing optocouplers because they can reduce the power consumption and take up less board space while offering the same isolation capability.

Our isolated interface products integrated the digital isolation and transceivers into single chip, such as the isolated RS-485/RS-422 transceivers, isolated CAN transceivers, isolated I2C, isolated digital I/O; We also offer the isolated interface products with internal power supply, that include isolated RS-485/RS-422 transceivers with DC-DC converter, isolated CAN transceivers with switching power supply. These high-integration solution can help customers to increase reliability and simplify designs while providing the highest levels of protection on the market.

Chipanalog’s isolated power supply devices provide 0.65W, isolated DC-DC converter with up to 5kVRMS isolation rating. These devices integrate most of the components needed for an isolated power supply —switching controller, power switches, micro-transformer, soft-start, protection circuit etc. — into a single, compact SOIC package. The result is an efficient and compact fully integrated solution that is easy to comply with EMI requirements and makes power-supply design as easy as possible.

Our isolated amplifier/ADC integrates precision isolated amplifier and isolated modulator, optimized for shunt resistor-based current sensing or other small signal measurement applications including industrial control, industrial power supply, frequency inverters, automotive driver etc. areas.
