Other Parts Discussed in Thread: OPA140, OPA189, OPA209
OPA145 is marketed as 20 V/µs slew rate. Figure 6-37 of the datasheet shows slew-rate induced distortion already at ~25 kHz for a 30 V supply.
I am wondering if this is a mistake in the datasheet or how it is determined..
For comparison the OPA140 datasheet (nominally the same slew rate of 20 V/µs) shows the correct frequency (way above 100 kHz).
