PRODUCTION DATA
The maximum voltage at the RG pin is given by the following inequality:
where
All the gain resistors (RGAIN) values which respect the previous inequality are allowed. The graphical representation of Figure 7-3 helps in the selection.
All the combinations (VSENSE , RGAIN) below the curve are allowed.
As a consequence, once selected, the gain (RGAIN) and the VSENSE range is fixed, too.
For example if an application required a Gain of 10, RG will be 50 kΩ and VSENSE will be in the range 10 mV to 100 mV.
