auto-zero to less than 10V, zero drift of less than 1V/oC, input bias current of 10pA (Max), and rollover error of less than one count. True differential inputs and reference are useful in all systems, but give the designer an uncommon advantage when measuring load cells, strain gauges and other bridge type transducers. Finally, the true economy of single power supply operation, enables a high performance panel meter to be built with the addition of only 10 passive components and a display. Th.
