(Note 3)

Note 1:

These parameters were characterized using the circuit in Figure 1-7. In Figure 2-37 and Figure 2-38, there

is an IMD tone at DC, a residual tone at 1 kHz, other IMD tones and clock tones.

High gains behave differently; see Section 4.3.3, Offset at Power Up.

tODR includes some uncertainty due to clock edge timing.
