9 Detailed Description

9.1 Overview

These devices offer low offset and long-term stability by means of a low-noise, chopperless, bipolar-input-

transistor amplifier circuit. For most applications, external components are not required for offset nulling and

frequency compensation. The true differential input, with a wide input-voltage range and outstanding common-

mode rejection, provides maximum flexibility and performance in high-noise environments and in noninverting

applications. Low bias currents and extremely high input impedances are maintained over the entire temperature

range.

These devices are characterized for operation from 0°C to 70°C.

9.3 Feature Description

9.3.1 Offset-Voltage Null Capability

The input offset voltage of operational amplifiers (op amps) arises from unavoidable mismatches in the

differential input stage of the op-amp circuit caused by mismatched transistor pairs, collector currents, current-

gain betas (

β), collector or emitter resistors, et cetera. The input offset pins allow the designer to adjust for these

mismatches by external circuitry. See the Application and Implementation section for more details on design

techniques.

9.3.2 Slew Rate

The slew rate is the rate at which an operational amplifier can change its output when there is a change on the

input. The OP07 has a 0.3-V/

μs slew rate.

9.4 Device Functional Modes

The OP07 is powered on when the supply is connected. It can be operated as a single supply operational

amplifier or dual supply amplifier depending on the application.
