1. Guaranteed by design, unless otherwise specified.
2.
R
LOAD
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.
