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 Ω resistor, which is trimmed to ±3%. 3For V CM ≤ 20 V. For VCM > 20 V, VOL 1 mV/V × V CM. 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. |
