Note 1: The slew rate is limited by the GBWP; the large signal step response is dominated by the small signal bandwidth.

2: These parameters were characterized using the circuit in Figure 1-8. In Figures 2-75 and 2-76, there is an IMD tone at DC, a residual tone at 100 Hz and

other IMD tones and clock tones.

3: High gains behave differently; see Section 4.4.4 “Offset at Power-Up”.

4: tSTR, tSTL, tIRC, tIRD and tOR include some uncertainty due to clock edge timing.
