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 a 100 k
Ω
resistor, which is trimmed to
±
3%.
