Package Type

General Description

The TC913 is the world's first complete monolithic, dual

auto-zeroed operational amplifier. The TC913 sets a

new standard for low power, precision dual-operational

amplifiers. Chopper-stabilized or auto-zeroed amplifi-

ers offer low offset voltage errors by periodically sam-

pling offset error, and storing correction voltages on

capacitors. Previous single amplifier designs required

two user-supplied, external 0.1µF error storage correc-

tion capacitors — much too large for on-chip integra-

tion. The unique TC913 architecture requires smaller

capacitors, making on-chip integration possible.

Microvolt offset levels are achieved and external

capacitors are not required.

The TC913 system benefits are apparent when con-

trasted with a TC7650 chopper amplifier circuit imple-

mentation. A single TC913 replaces two TC7650's and

four capacitors. Five components and assembly steps

are eliminated.

The TC913 pinout matches many popular dual-opera-

tional amplifiers: OP-04, TLC322, LM358, and ICL7621

are typical examples. In many applications, operating

from dual 5V power supplies or single supplies, the

TC913 offers superior electrical performance, and can

be a functional drop-in replacement; printed circuit

board rework is not necessary. The TC913's low offset

voltage

potentiometers often needed with bipolar and low

accuracy CMOS operational amplifiers.

The TC913 takes full advantage of Microchip's

proprietary CMOS technology. Unity gain bandwidth is

1.5MHz and slew rate is 2.5V/µsec.
