  • OPA340: PSPICE for TI taking long to run in single supply

    Resolved
    Part Number: OPA340 Other Parts Discussed in Thread: TINA-TI Hello TI, I am interested in using OPA340. It works well in TINA-TI in a single supply configuration (+5V, 0). Unfortunately when I load into PSPICE for TI the model takes too long to converge…

  • OPA340: Output waveform question for OPA340

    TI Thinks Resolved
    Part Number: OPA340 Hi TI Expert, I design a TINA circuit for OPA340. When I run AC simulation from 10HZ to 1MHZ. I cannot understand for the Gain waveform. f=1/2πR2*C1=1KHZ, But the Gain waveform is raising from 1K to 20K. And the gain waveform is going…

  • OPA340: OPA340 driving TLV2548 oscillation

    Resolved
    Part Number: OPA340 Other Parts Discussed in Thread: TLV2548 , Hi, I have a OP340 in non-inverting configuration driving into a TLV2548 ADC. At lower steady state amp input voltages (in the region of 0.65V) I'm see an oscillation at the output of the amp…

  • OPA340: Sallen Key Filter oscillation on OPA340

    Resolved
    Part Number: OPA340 We implemented a low pass Sallen Key filter with a cutoff frequency of 4.8 Mhz, with balance R=330 and C=100pF. With a bandwidth of 5.5Mhz, significant filtering was not expected, however the OPA340 seem to make signal worse the input…

  • OPA340: Die area needed to predict radiation susceptibility

    Resolved
    Part Number: OPA340 Other Parts Discussed in Thread: OPA547 , INA121 Do you have radiation data for the OPA340NA? If not, could you provide the die area? This would be used to predict susceptibility to space radiation. Thanks, Carolyn Sleeper
