DESCRIPTION

The SC7106 and SC7107 are high performance, low power, 3

A/D converters. Included are seven segment decoders, display drivers, a

reference, and a clock. The SC7106 is designed to interface with a liquid

crystal display (LCD) and includes a multiplexed backplane drive; the

SC7107 will directly drive an instrument size light emitting diode (LED)

display.

The SC7106 and SC7107 bring together a combination of high

accuracy, versatility, and true economy. It features auto-zero to less than

10

µV, zero drift of less than 1µV/°C, 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 (SC7106), enables a high performance panel meter to be built

with the addition of only 10 passive components and a display.
