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 the resistor R12 (see Figure 16) which is 100 k
,
trimmed to
± 3%.
3For V
CM ≤ 20 V. For VCM > 20 V, VOL 1 mV/V × VCM.
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—see the section Product Description and Figure 3.
All min and max specifications are guaranteed, although only those marked in boldface are tested on all production units at final test.
Specifications subject to change without notice.
