We will use TLV171-Q1 as voltage follower circuit.
We require a gain error of ±0.01dB with up to 30kHz on this device.
I think that probably it is no problem by looking at the figure 12. Closed-Loop Gain vs Frequency.
Does it fit within ±0.01dB in 30kHz?
The attenuation at 8 MHz appears to be about -7 dB, but can you see the exact value?
Should it be considered that 8 MHz or more attenuates at 40dB/dec?
