OPA2347: ESD class and ESD voltage rating of pins

Part Number: OPA2347
Other Parts Discussed in Thread: OPA2348, OPA2313, TLV2333


What is the ESD class and voltage rating of ESD protection of the pins on this device?

Thank you,

    Hello HSG,

    Unfortunately, this part is an older Burr-Brown part from right around the time TI purchased Burr-Brown and we do not have the original ESD qualification data for this part.  I can offer you two other data points.

    1. The OPA2347YZDR passed ESD testing using the Charged-Device Model (CDM) at 1kV.  However, this is a chip-scale package. So, performance may differ.

    2. The OPA2348 passed CDM testing at 1.5kV.  This is a similar part, but again, not the same.  So, performance may differ.

    Again, please remember that this data is not indicative of how your part will perform.  But, this is all I can give you now.



  • Can you please do a research and confirm the ESD level of PN: OPA2347UA and update that info. onto its datasheet?



  • Hello Dat Pham1,

    Thanks for your follow up question on the ESD rating of the OPA2347UA. Please understand that the device is about 20 years old, and we're doing our best to find the information you request. However, it may not be available...we should know soon.

    In the meantime, I recommend evaluating alternate devices for your application. One similarly priced device you may consider is the OPA2313. Though Iq is 85uA max over temp, it has approximately triple the bandwidth. It is also a 5V, RRI/O device with ESD ratings in the data sheet. Another option is the TLV2333, which has 350kHz bandwidth with a max Iq of 28uA over temperature. This device also has ESD ratings in the data sheet, but is more expensive due to overall better performance (for example, Vos max is just 15uV, much better drift, lower noise, etc.).

  • Hello Dat Pham1,

    We located a reliability report for the OPA2347UA from February of 2001 with the following information:

    ESD test     Level     Pass/Fail

      HBM          2 kV         3/0

       MM          500 V       3/0

    If the information needs to be in the data sheet then I recommend evaluating one (or both) of the potential alternatives I already mentioned. Actually, I recommend evaluating the other devices in your system anyways.
