Figure 14 on page 12 illustrates a load cell bridge fully differential 3.8 V into the CS5510/12 A/D
amplifier with a gain of 768 V/V. The load cell is
excited with +5 V and has a 1 mV/V sensitivity. Its
full scale output signal is amplified to produce a
converter. This circuit operates from +5 V.
A similar circuit operating from +3 V can be
constructed using the CS5540/CS5541 A/D con-
verters.
