NOTES
1
Specified for default mode, i.e., with no external components. The overall gain is trimmed to 0.5%, while the individual gains of A1 and A2 may be subject to a
maximum
±
3% tolerance. Note that the actual gain in a particular application can be modified by the use of external resistor networks.
2
The actual output resistance of A1 is only a few ohms, but access to this output, via Pin 3, is always through the resistor R12 (see Figure 16) which is 100 k
,
trimmed to
±
3%.

refers to common-mode voltages—see the section Product Description and Figure 3.
All min and max specifications are guaranteed, although only those marked in
