Analog Features Supply Regulator A bandgap-stabilized supply-regulator is on-chip while the pass-transistor is external. The bridge-type sensor is typically powered by the regulated supply (typically 4.75V). For ratiometric operation, the supply-regulator can be disabled by connecting together the unregulated and ...
