  • OPA333: Phase margin equation

    • Resolved
    Part Number: OPA333 Hi, I was hoping you could help me with some data that keeps coming up in TI

  • OPA333: Input Offset Current Specs

    • Resolved
    Part Number: OPA333 Hello, just trying to sort out an error budget with a circuit using OPA333

  • RE: OPA333: TI Precision Labs - Op Amps: Stability 1

    Hi d_zero, Your Tina model works as Kai indicated. Please use Kai's Transient Analysis window setting (run up to 10msec and use Zero initial values) and you should see the instability or oscillation, because there is Q at approx 6.7kHz and does...

  • RE: MicroVolt signal Amplification

    Hi Shashank, Thank you for your post. I can help you. 1. Looking into the input of the amp, the 10nF and 100nF capacitors are in parallel: 110nF. Frequency = 1/(2*pi*R*C) = 1/(2*pi*7.5k*110n) = 193Hz 2. R1 & R2 is your half-bridge. What kind...

  • RE: OPA333: How to understand PSRR parameters？

    There is only one PSRR spec in the OPA333 datasheet where Vos changes with the variation in the supply voltage: ΔVos=ΔVs*PSRR so if the supply voltage changes from 5V to 2V, then Vos will typically change by: ΔVos=(5V-2V)*1uV/V=3uV....

  • OPA333-Q1: performance vs OPA333

    TI Thinks Resolved
    Part Number: OPA333-Q1 Can you detail the differences bettween OPA333 and the automotive rate OPA333-Q1 ? comparing both datasheet I cannot see the difference. failure rate ? burn in ?

  • RE: PGA113: output amplitude distortion

    Hi Betty, There are a couple of issues with the circuit. - The signal is AC coupled on the circuit above, where the capacitor C28 (1uF) is used as a DC blocking capacitor. However, the DC input voltage at the PGA113 input is undefined since the input...
