General Description

The TC1034/TC1035 are single CMOS operational

amplifiers for low power applications.

They have a typical operating supply current of 6µA,

which is constant over the supply voltage range of 1.8V

to 5.5V. The Op Amp has a rail-to-rail input and output

which allows operation at low supply voltages with

large input and output signal swings.

An active low shutdown input, SHDN, is available on

the TC1035 and disables the op amp, placing its output

in a high-impedance state. The TC1035 draws less

than 0.1µA when the shutdown mode is active.

Packaged in a 5-Pin SOT-23A (TC1034) or 6-Pin SOT-

23A (TC1035), these single operational amplifiers are

ideal for applications requiring high integration, small

size and low power.
