Übersicht
Description
Key features include a high common-mode transient immunity, low power consumption, and a wide supply voltage range. The ADUM2250ARWZ provides galvanic isolation, ensuring that digital signals can be transmitted across an isolation barrier without a direct electrical connection, which enhances safety and prevents ground loops.
The package is compact, often available in a wide-body SOIC (Small Outline Integrated Circuit) format, which facilitates easy integration into various circuit designs. Its reliability and performance in harsh environments make it a preferred choice for engineers looking to implement digital isolation in their systems.
Equivalent
1. Silicon Labs' Si8600 series
2. Texas Instruments' ISO7420 series
3. Broadcom's ACMD-7402
These alternatives offer similar functionality, such as bidirectional I2C communication and galvanic isolation. It's important to verify specific technical requirements like data rate, isolation voltage, and packaging to ensure compatibility with your application.
Features
Key features include:
1. Isolation Voltage: Provides 2500 Vrms isolation for up to 1 minute.
2. Data Rate: Supports data rates up to 1 Mbps, suitable for many I²C applications.
3. Low Power Consumption: Offers low power operation which is crucial for battery-powered devices.
4. Safety and Protection: Meets safety standards for reinforced isolation, offering protection in high-voltage applications.
5. Compact Package: Available in a 16-lead SOIC package, facilitating space-efficient designs.
6. Wide Temperature Range: Operates over an extended temperature range, making it suitable for various industrial applications.
Overall, the ADUM2250ARWZ is ideal for applications requiring reliable data communication and electrical isolation.
Pinout
The device is housed in a 16-lead SOIC package, meaning it has 16 pins in total. Key features include:
- Pin 1-8: These pins serve the digital input/output functions on one side of the isolator, typically designated for the controller side of the I2C bus. They include the SDA (Serial Data Line) and SCL (Serial Clock Line) along with power (VDD1) and ground (GND1) pins.
- Pin 9-16: These are the corresponding digital input/output pins on the other side of the isolator, typically designated for the peripheral side of the I2C bus, mirroring the functions of pins 1-8. This side also includes power (VDD2) and ground (GND2) pins.
The ADUM2250ARWZ provides galvanic isolation between the two I2C bus sections, enhancing safety and noise immunity.
