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.
