  • OPA814: High Speed Sample-and-Hold Amplifier Design with OPA814/OPA615

    Part Number: OPA814 Other Parts Discussed in Thread: OPA615 , OPA656 , THS4631 , OPA817 , TINA-TI Hello E2E Experts, Good day. I am designing a circuit to measure the in-situ gate threshold voltage Vth of a MOSFET. The signal to be measured ranges…

  • OPA814: About Figure 6-21

    TI Thinks Resolved
    Part Number: OPA814 Tool/software: I have doubts about the graph in Figure 6-21 of the OP814 datasheet, which shows Current Noise Density vs Frequency (it differs too much from the characteristic curves of OPA656N and other op-amps). It seems that this…

  • OPA814: Maximum continuous output current

    TI Thinks Resolved
    Part Number: OPA814 Other Parts Discussed in Thread: OPA817 The datasheet for the OPA814 op-amp indicates that the "linear output drive" [current] is typically 70mA into a 100-ohm load (for VOUT =+/-1V) and the "short-circuit" current is 90mA. However…
