Other Parts Discussed in Thread: OPA827, TINA-TI
Dear Ladies and Gentlemen,
What is the expected gain error at 100 kHZ and 1 MHz of the simple voltage follower with OPA828 op-amp? I simulated it with Spice and got 60 ppm at 100 kHz and 5700 ppm at 1 MHz. Very high...
For comparison, for the voltage follower with OPA827 I got 3 ppm and 285 ppm, respectively.
Is really the gain error of the OPA828 worse than OPA827 in this application?
The gain error is defined as 1E^6*(Uout-Uin)/Uin, where Uout and Uin are magnitudes of the output and input voltage of the follower, respectively. The supply voltage was -15V/+15V.
Thank you and best regards,
