requirements, internal reference enabled.
(2) Please refer to the
Theory of Operation
section for more information with respect to output voltage configurations.
(3) See Figure 11 for gain and offset adjustment connection diagrams when using the internal reference.
(4) The minimum value for REF

+14V and +4.75V, where +4.75V is the minimum voltage allowed.
(5) Reference low-pass filter values: 100kΩ, 1.0µF (see Figure 14).
