Features and Benefits

  • 2 A peak drive output capability
  • Output power device resistance: <2 Ω 
  • Low propagation delay: <51 ns 
  • Operating temperature range: −40°C to +125°C 
  • Output voltage range to 35 V 
  • Output and input undervoltage lockout (UVLO)
  • Pad placement for multiple switch types
  • Screw terminals for easy connectivity

Product Details

The evaluation boards EVAL-ADuM4120EBZ and EVAL-ADuM4120-1EBZ support the ADuM4120/ADuM4120-1 single-channel gate drivers with an integrated miller clamp. Analog Devices, Inc., iCoupler® technology provides isolation between the input signal and the output gate driver. The EVAL- ADuM4120-1EBZ option is populated with the ADuM4120-1 that does not contain an internal input glitch filter, resulting in lower propagation delays.


The instructions and components in UG-1109 apply to both the EVAL-ADuM4120EBZ and EVAL-ADuM4120-1EBZ.


The ADuM4120/ADuM4120-1 provides operation with voltages of up to 35 V. The high common-mode transient immunity (CMTI) and robust drive strength makes the ADuM4120/ADuM4120-1 an excellent fit for fast switching technologies.


The EVAL-ADuM4120EBZ evaluation board facilitates testing of the propagation delay, drive strength, and input logic of the device.


For complete information about the ADuM4120/ADuM4120-1, refer to the ADuM4120/ADuM4120-1 data sheet that should be consulted in conjunction with UG-1109 when using the evaluation board.
