REF3030: Figure 7-8. Output Impedance vs Frequency Unit

Part Number: REF3030
Other Parts Discussed in Thread: REF35

Hello,

I'm looking into the datasheet for the above part SBVS0321 from July 2022. Figure 7-8 refers to unit Output Impedance (dB). Is this a typo and should read Output Impedance (Ohms) instead, or how to convert that into ohms?

Best Regards Markus Greither

P. S.: There seems to be another glitch in the datasheet in diagram 7-18: The title says 1-mA to 6-mA, but the trace reads 6mA to 0mA.

    Hi Markus 

    Thank you very much for pointing out Figure 7-8 and 7-18. The unit of dynamic impedance is ohm only and thereis typo in title of figure 7-18. We will change that in our data sheet revision. 

    We have released new reference REF35 which is pin compatible with REF30 and it has better tempco (6ppm/C ) and supply IQ (680nA). Let me know if you need support for this device. 

    Regards
