Key Differentiators
- Lower data rate but sufficient for many applications (vs ADUM1400BRWZ)
- All channels in one direction (vs ADUM1401ARWZ)
- Lower cost compared to higher-speed variants (vs ADUM1400CRWZ)
Design Notes
Place 0.1Β΅F bypass capacitors close to VDD1 and VDD2 pins to ensure stable operation. Use a solid ground plane under the device to minimize noise coupling. Keep the isolation barrier clear of copper traces to maintain the specified isolation voltage.
The ADUM1400ARWZ consumes approximately 1.3mA per channel. Ensure the power supply can handle the total current for all channels. For higher data rates, consider using the ADUM1400BRWZ or CRWZ variants, but verify power requirements.
Do not exceed the absolute maximum ratings for supply voltage or isolation voltage. Ensure the enable pin (VE1) is properly driven to avoid unintended output states. For applications requiring higher data rates, select the appropriate variant to avoid signal integrity issues.
