  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....

  RE: OPA2333: I want to know the inner structure and operation theory about OPA2333AIDGKR!

  Morning Yang Kun, These choppers are actually quite involved internally, when the 1st BurrBrown one was developed (the OPA333) there was some effort to explain the internals - here is one of those,
