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.
A2 gain is trimmed to 0.5% with a 0.01% 1 k
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.
The actual output resistance of A1 is only a few ohms, but access to this output, via Pin 3, is always through an 80 k
Referred to the input (Pins 1 and 8).
