The ADM3062EARMZ is a 3.3 V protocol translator transceiver with galvanic isolation, designed to provide bidirectional communication between an RS-485/422 serial bus and an IC device with a high speed I2C/SPI interface. The ADM3062EARMZ has an integrated 2kV isolation barrier between the serial bus ports and the I2C/SPI interface, allowing high speed communication with an I2C/SPI device while providing isolation from the serial bus application.

Application field of ADM3062EARMZ

The ADM3062EARMZ can be used for selecting isolated I2C/SPI devices for applications where reliability and robustness are paramount. Some examples of applications for the ADM3062EARMZ include industrial automation and process control, industrial networking, motor control, electrical grid infrastructure, automotive, military and aerospace. These are just some potential applications for this transceiver, the real possibilities are virtually limitless.

Working principle of ADM3062EARMZ

The ADM3062EARMZ uses a single supply of 3.3 V and operates with a maximum data rate of 1 Mbps. It also has selectable slew rates of 12V/µs and 17V/µs as well as a configurable receive threshold voltage to allow flexible operation. The I2C/SPI interface supports I2C Standard, Fast, and High Speed (HS) modes. It also supports SPI clock frequencies up to 8 MHz.

The ADM3062EARMZ comes with a low power shutdown mode which reduces power consumption to less than 2 mW when not actively communicating. When the part is not in use, it can be put into a state where it uses virtually no power at all.

The ADM3062EARMZ uses Galvanic Isolation technology to isolate the I2C/SPI bus from the RS-232/422/485 bus, which is critical for noise immunity in high speed serial communications. The ADM3062EARMZ can also detect bus idle conditions and turn off the receiver sections in order to reduce power consumption.

The ADM3062EARMZ also features protection against short circuit and over-voltage conditions to ensure that it is not damaged by unexpected power surges. It has a data rate of up to 1 Mbps, meaning it can support very fast physical layers such as 10BaseT.

The ADM3062EARMZ can be used in Industrial Ethernet applications, as well as other types of digital bus applications. It is capable of transmitting data over two twisted-pair cables for full-duplex operation and can be used in point-to-point or broadcast bus systems.

In conclusion, the ADM3062EARMZ is an ideal device for bidirectional communication between an RS-485/422 serial bus and an I2C/SPI device. It has a maximum data rate of 1 Mbps, integrated 2kV isolation, low power shutdown mode, selectable slew rates and configurable receive threshold voltage. Its features make it suitable for use in a variety of industrial and commercial applications.
