  THS4211: Too much noise, I need a replacement !

  TI Thinks Resolved

  Part Number: THS4211 Hello everyone, I am using the THS4211 to amplify the signal coming from a current sensor ( for High Frequencies ) with a quite high gain ( from 40 to 60dB ) Are you aware of a suitable replacement that has much less noise ? I...

  RE: LM7372: looking for a part that has faster settling

  Hello Steve, There is also the THS4211, however it doesn't meet your voltage noise requirement. If that is okay with your system, that's another part to consider. Thanks! -Karan

  Opamp input capacitance min/max . THS4211.

  Hello ti community, I just want to know if there is any sort of information available about the accuracy of input capacitance of opamps in general (specifically THS4211). The datasheets usually specifies only single value for such information and don't...

  RE: THS4211, input attenuator introduces offset voltage at the output.

  I just realized It was because of the bias current of the opamp.

  RE: OPA858: OPA858

  Hi Sean, Thanks for the suggestion. I looked in to the data sheet of THS4211. Just to confirm, If I want input common mode voltage range from say 0V to 0.9V (or 100mV to 900mV), I need to use Vs+ = 5V and Vs- = -5V. And if I use Vs+ = 5V and Vs- ...

  RE: Difference in AC voltage amplitude displayed by AC analysis tool and virtual oscilloscope

  Hi, Could it be because the "Calculate nodal voltages" function in the "AC analysis" option in the "Analysis" menu doesn't take into account the possibility of the circuit instability and resulting oscillations (there...

  RE: LMH6629 transimpedance amplifier; 1. I'm using a low (62 Ohm) feedback resistor; 2. Compenstated and similar plug-in replacement for the WDFN-08 packaged version of this LMH6629?

  Hi Ken, Please keep in mind that the THS4211 quiescent supply current is as high as 24mA (=10V * 24mA= 240mW). So, you would need to add the load-related dissipation to this value. Assuming the output voltage is at ground (0V) when you are sinking 50mA...

  RE: OPA657

  Hello Nishant, Unfortunately with the package style you have chosen, we don't have an alternate amplifier to be a drop-in replacement with higher bandwidth that also has JFET inputs. You can try using the THS4211 and THS4271 both of which have higher...

  RE: THS4211D

  Hello, The OPA695 (running on 12V supplies and GND) and the THS3091 would both do well in a high voltage pulse amplification application. The THS4211 has high BW but is limited in slew rate. In such cases current-feedback amplifiers (CFA) are a much...
