Digital isolators have become increasingly important in many applications due to their ability to support high data rates and provide galvanic isolation.The MAX12930FASA+ is a digital isolator which provides up to 2Mbps of optical isolation for a variety of systems.

The MAX12930FASA+ is a full-duplex, low-power, digital isolator, and is comprised of a complete channel with both transmit and receive optical isolator. This allows it to isolate both data lines, eliminating the need for additional optocouplers. It also offers protection against high-level overvoltages, making it suitable for a range of mixed-signal and power-electronics applications.

The MAX12930FASA+ is ideal for systems that require high speed data transmission with high degree of galvanic isolation. It can be used to interface with a microcontroller, or as an isolation barrier between different parts of a power electronics circuit. It can also be used to provide voltage or communications isolation in industrial, automotive, and medical applications.

The operating principle of the MAX12930FASA+ is based on the transmission of light through a high speed, low power VCSEL driver and a high speed, low power PIN photo detector. The VCSEL driver transmits a digital signal along an optical link that is then received by the PIN photo detector. This process of signal conversion in the isolator allows for a complete data isolation without any impact to the signal integrity.

The MAX12930FASA+ is designed to perform at 2Mbps with a low supply current of 2.5mA. It also offers a selectable slew rate that can be adjusted to best match the application. The isolator is packaged in a 16-pin TSSOP package, making it suitable for high-density PCB mounting.

In summary, the MAX12930FASA+ is an ideal digital isolator for a variety of applications where data signal integrity and galvanic isolation are required. It is capable of providing up to 2Mbps of optical isolation and offers a slew rate selectable for best performance.It is also available in a convenient 16-pin TSSOP package for high density mounting.
