NOTES
1Specified 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.
2The actual output resistance of A1 is only a few ohms, but access to this output, via Pin 3, is always through a 100 k
resistor, which is trimmed to ±3%.
3For V
CM ≤ 20 V. For VCM > 20 V, VOL

4Referred to the input (Pins 1 and 8).
5With V
DM = 0 V. Differential mode signals are referred to as V DM, while VCM refers to common-mode voltages.
Specifications subject to change without notice.
