General Description
The TC1043 is a mixed-function device combining two
general purpose op amps, two general purpose com-
parators, and a voltage reference in a single 16-Pin
package.
This increased integration allows the user to replace
two or three packages, saving space, lowering supply
current, and increasing system performance. A shut-
down input, SHDN, disables the op amps and one of
the comparators, placing their outputs in a high-imped-
ance state. The reference and one comparator stay
active in shutdown mode. Standby power consumption
is typically 6µA. Both the op amps and comparators
have rail-to-rail inputs and outputs which allows opera-
tion from low supply voltages with large input and out-
put signal swings.
Packaged in a 16-Pin QSOP, the TC1043 is ideal for
applications requiring high integration, small size and
low power.
