  • OPA828: OPA828

    Resolved
    Part Number: OPA828 Tool/software: When operating with +15v and gnd as the supplies to the op-amp, how close to zero volts can the output drive? (load < 1mA) ? Does operating close to the negative rail (ground) reduce the op-amp precision (drift, offset…

  • OPA828: Output offset when input is zero.

    Part Number: OPA828 Other Parts Discussed in Thread: OPA320 , OPA328 , OPA3S328 Tool/software: Hello, I find my TIA output is not correct. And when I remove the input (so nothing connect to RF1), the output should be near zero. But one of my boards…

  • OPA828: Electrostatic discharge

    TI Thinks Resolved
    Part Number: OPA828 Other Parts Discussed in Thread: OPA192 , Tool/software: Hello team, My customer is evaluating OPA828. The electrostatic discharge of OP828 is ±2000V. But some opamp (ex OPA192) cases are ±4000V. Is this due to the difference…

  • OPA828: Improved Howland Current Pump output current with chipped edges

    TI Thinks Resolved
    Part Number: OPA828 Tool/software: Hi, I am simulating Howland charge pump with OPA828. I see the edges are getting chipped off in my output. Any idea on why this could happen? Thanks, The input rise time is 10uS and 5V at 100Hz.
