7.4.2.2 Range 2: VCM is 1.8 V to VS
In this range, the maximum voltage at the RG pin is related to the common-mode voltage and VSENSE. So all the RGAIN resistor values which respect the following inequalities are allowed:
Equation 5. VRG ≤ min (Vout_max; (VCM – Vsense– 250 mV))
where
- VRG = VSENSE * RGAIN * Gm
- Vout_max is the maximum allowable output voltage according to the Section 6.5, Section 6.6, and Section 6.7.
The graphical representation in Figure 7-4 helps in the selection.
All the combinations (VSENSE, RGAIN) below the curves for given VCM and supply voltage are allowed.
Figure 7-4 Allowed Gains for Range 2Also in this range, once selected, the RGAIN (Gain) and the VSENSE range is fixed too.
