General Description
The TC1030 is a quad CMOS operational amplifier
designed for low power applications. It has a typical
operating supply current of 20µA 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.
