    TI Thinks Resolved
    Part Number: OPA835 Other Parts Discussed in Thread: TINA-TI Tool/software: Hi there, I am trying to simulate the new opa835 in LTspice. I'm using the model provided on the official website ( www.ti.com/.../slom221). Whatever I try, I get the following…

  • OPA835: /PD pin of OPA835

    TI Thinks Resolved
    Part Number: OPA835 Hi team, Can I know for the pin5 (/PD) of OPA835, is it allowed to float this pin if customer does not want to use it? Regards, Xiaoying

  • OPA835: We want to use it into our application and generate a Symbol from this Schematic View using TI- PSPICE Schematic Capture

    TI Thinks Resolved
    Part Number: OPA835 Dear All, Please advice me how to generate Symbol from a Schematic view using TI PSPICE Simulation/Capture tool. Looks like the New Symbol option is always dimmed, no matter what. Your help is greatly appreciated as we are closing…

  • OPA835: Input bias current

    Resolved
    Part Number: OPA835 Other Parts Discussed in Thread: PSPICE-FOR-TI , TINA-TI , OPA836 When I model a test amplifier using a OPA835 in Ti-Pspice the simulated input bias currents are too high, around 10ua. If I model the same circuit in TinaTi the currents…

  • RE: OPA835: OPA835 stability simulation

    Resolved
    Hello Javier, Thank you for the clarification. Because you are using the part in a single supply configuration, you will want to reference your circuit to midsupply (2.5V). This way the amplifier is not railing at DC and the amplifier can utilize its…

  • INA821: Large DC offset when REF < 1.53 V

    Part Number: INA821 Other Parts Discussed in Thread: OPA835 Hello, we have the following circuit: The input signal is at Vcm = 2.5 V, Vdiff up to 12 mV, frequency ranging from 1 kHz to 1 MHz. We want the output signal to swing around 1.0 V. However,…

  • OPA835: OPA835 asymmetric power supply

    Part Number: OPA835 Hi team, My customer wants to use OPA835 to do an inverting amplifier. The input signal is ±100mV. The gain is set to be 5. However, due to the power supply restriction, the VS+ is 3.6V and the VS- is -1V. Is it reliable to use the…
