1. Guaranteed by design, unless otherwise specified.

RLOAD is the resistive load connected to VSSA or to VDDA.

3. R2 is the internal resistance between the OPAMP output and th OPAMP inverting input. R1 is the internal resistance

between the OPAMP inverting input and ground. PGA gain = 1 + R2/R1.
