DAC11001A: output range

ttd

Part Number: DAC11001A
Other Parts Discussed in Thread: OPA828, OPA455, OPA462, OPA827

Dear Technical Support Team,

I'd like to make a analog output system with DAC11001A and Opeamp.

①

Is it possible to output ±15V with DAC11001A?

EVM has OPA828 for VREFP and VREFN and user guide describes ±15V supply to VCC on board.

This VCC makes  VREFP and VREFN with OPA828.

②

Could you suggest the companion Opeamp for output buffer of DAC?

I'd like to make a ±25V output with Opeamp  from ±15V of DAC.

I'm considering the LTC6090 and OPA455 and OPA462 etc.

Best Reagards,

ttd

    Hi,

    DAC11001A can be used to generate a maximum of +/-15V with the following conditions

    VCC = 18V, VSS = -18V , REFp = +15V & Refm = -15V.

    We need to have a head room of 3V from VCC to Refp and VSS to Refm. Hope this is understood.

    For buffering reference, I recommend OPA827. For outputs also OPA827 will be a good choice.

    Regards,

    AK
