ADC128S102QML-SP: Output current

Part Number: ADC128S102QML-SP

What is the maximum output current from DOUT? Is there a performance graph? We need to add a voltage divider on the output to drop the voltage, but the trace capacitance causes a slow rise/fall time on the signal. But we don't want to exceed the recommended output current level. We need to optimize the resistor values to minimize rise time (lower resistance) with minimum current (higher resistance). Any recommendations?

  • Hello Barry

    We have not characterized the output current.  All testing and characterization was done with the current limited to conditions shown in the datasheet.

    The characterization showed that Voh was very close to the rail, indicating that there is plenty headroom for the output current.

    The output structures were designed to handle at least 5 mA reliably, but I don't know if the driver could actually supply that.

    Could you lower the Vd supply voltage?
