Figure 14onpage 12 illustrates a load cell bridge

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

fully differential

± 3.8 V into the CS5510/12 A/D

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.
