Instructions for Using the DG200ABA
Power Supply Connection:
- Connect VDD1 to the power supply on the input side.
- Connect VDD2 to the power supply on the output side.
- Ensure both VDD1 and VDD2 are within the specified range (3.0V to 5.5V).
Signal Input:
- Connect the digital signal to be isolated to the input pin (IN).
- The input signal should be within the valid logic levels defined by VIH and VIL.
Signal Output:
- The isolated output signal will be available at the output pin (OUT).
- Ensure the load connected to the output pin is within the specified current limits (IOH and IOL).
Propagation Delay:
- The propagation delay (tPLH and tPHL) should be considered when designing the system to ensure proper timing.
- For best performance, keep the propagation delay within the typical range (25 ns).
Isolation:
- The DG200ABA provides galvanic isolation up to 2500 Vrms for 1 minute.
- Ensure that the isolation barrier is not exceeded to avoid damage to the device.
Operating and Storage Conditions:
- Operate the device within the specified temperature range (-40°C to 125°C).
- Store the device within the storage temperature range (-65°C to 150°C).
Handling Precautions:
- Handle the device with care to avoid static discharge.
- Follow standard ESD (Electrostatic Discharge) precautions when handling the device.
By following these parameters and instructions, you can effectively use the DG200ABA in your digital isolation applications.
