General Description

The TC1030 is a quad CMOS operational amplifier

designed for low power applications. It has a typical

operating supply current of 20

µA which is constant over

the supply voltage range of 1.8V to 5.5V.

Each op amp has rail-to-rail inputs and output which

allow operation at low supply voltages with large input

and output signal swings. Two active low shutdown

pins are provided. One pin disables op amp B while the

other disables op amps C and D. Op amp A is always

active. When disabled, the outputs of op amps B, C and

D are in a high impedance state.

Packaged in a 16-Pin QSOP, the TC1030 is ideal for

battery operated applications.

The TC1030 is packaged in a 16-Pin QSOP, making it

ideal for battery operated applications.
