The overall gain is trimmed to a gain of 400 ±0.5% with the same 1 kΩ resistor. The gain of A1 (the ratio of overall gain to A2 gain) is used to adjust the overall gain and, therefore, is not trimmed explicitly to 40. Note that the actual gain to a particu- lar application can be modified by the use of an external resistor at Pin 4. 2The actual output resistance of A1 is only a few ohms, but access to this output, via Pin 3, is always through an 80 k Ω resistor, which is trimmed to ±3%. 3Referred to the input (Pins 1 and 8). 4With V DM = 0 V. Differential mode signals are referred to as V DM, while VCM refers to common-mode voltages. 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. |
