  • OPA2625: How to improve SNR, HD2 and HD3 of an 18-bit SAR ADC when OPA2625 is being used to drive the differential inputs of ADC?

    TI Thinks Resolved
    Part Number: OPA2625 Other Parts Discussed in Thread: OPA838 , THS4561 , THS4551 , THP210 , THS4541 , ADC3683 Hi, We have built an EVM for an 18-bit, 65MSPS SAR ADC for which we are using ADT1-6T+ transformer and OPA2625 in the below circuit configuration…

  • RE: OPA2626: Strange behavior of OPA2626

    Hello, The OPAx625 is the same design structure as OPA2626; the difference is the OPA2625 core has shutdown pin functionality. The OPA2626 does not have shutdown. If the test result is good with OPAx625 you are okay to evaluate and use OPA2626. You can…

  • RE: ADS1299: Piezoelectric sensor aquisition

    Hi, I have not used a charge amplifier. Is it same as Transimpedance Amplifier ? Would you mind describing/explaining a bit more about your circuit and application? When you say piezoelectric generates charges, does it have current flow? Let me understand…

  • PGA281: Is the PGA281 differential output capable of driving a SAR ADC directly ?

    TI Thinks Resolved
    Part Number: PGA281 Other Parts Discussed in Thread: ADS9110 , OPA2320 , THS4551 , OPA2625 , ADS8900B , OPA625 Is there a limitation of drivin SAR ADC directely ( kickback, settling , accuracy ). In my understanding, a ADC-driver needs higher BW to handle…

  • RE: THS4032: Opamp similar to THS4032 with enable/shutdown pin

    Resolved
    And actually that OPA2625 does not support 12V total supply, Dual with disable is actually a bit rare, that OPA2690 probably is the best part if the lowest power is not of interest.

  • RE: ADS8900B: Interface with FPGA

    Resolved
    Hi Youssef, Your understanding is correct, though you don't need to send anything over SDI if you just want to get data out. The datasheet recommends THS4551 as an FDA or OPA2625 if you want to build a discrete solution. I understand the datasheets…
