Part Number: THS4001 Other Parts Discussed in Thread: TLC2652 , Hi,
I am using the composite opamp with TLC2652 (chopper stabilized opamp) and THS4001 (High speed opamp).
If the input voltage is -5V from the battery V1 without the AC input, the…
Other Parts Discussed in Thread: THS4001 Hi all
The output voltage swing of THS4001 (ACTIVE) 270-MHz Voltage-Feedback Amplifier is from -15 to+15V and need to change to be 0-30V. Any suggestion.
Thanks
Sattam
Part Number: MC79L Other Parts Discussed in Thread: THS4001 , TPS56837 , TPS54531 Tool/software: For Converting the voltage from positive 12V to negative 12V, We are not sure what type of IC/chip to use.
So kind suggest some solution for this.
Please…
Hi Pavithra,
The simulations indicate that conceptually the TLC2652, THS4001 combination functions in the compound amplifier circuit you provided. The two Op amps are very different from each other, one being a legacy chopper and the other being a wide…
Samir,
Thank you very much for your answer.
Input Range is: 50mV-1V
Output Range is: 1V-3.3V.
Thus the Gain G = 20 actually is the maximum of gain.
Now we have several THS4001 and OPAMP847, do you think we can make a cascaded VFAs?
Thanks. …
Alberto,
The closed loop bandwidth of your 1st stage seems to be only 250kHz. At that point the OPA657 noise is around 1fA/rtHz which is very close to what is specified in the datasheet. Even with your 20MOhm resistor the output noise due to current…
While I am waiting, I should mention that my present design uses the THS4211 instead of the THS3001, THS4001 or THS4011. So far, the THS4211 seems to compare well in terms of cost and capabilities, but I am open to suggestions if changes to the circuit…
to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
