DIGITS, LCD/LED DISPLAY , A/D CONVERTERS FOR DMM
DESCRIPTION
The SC7106 and SC7107 are high performance, low power, 3

/

digit
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
10µV, 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.
