GENERAL DESCRIPTION
The OP07 has very low input offset voltage (75 µV max for
OP07E) which is obtained by trimming at the wafer stage. These
low offset voltages generally eliminate any need for external nulling. The OP07 also features low input bias current (±4 nA for
OP07E) and high open-loop gain (200 V/mV for OP07E). The
low offsets and high open-loop gain make the OP07 particularly
useful for high-gain instrumentation applications.
The wide input voltage range of ±13 V minimum combined with
high CMRR of 106 dB (OP07E) and high input impedace provides high accuracy in the noninverting circuit configuration.
Excellent linearity and gain accuracy can be maintained even at
: 75 V Max

high closed-loop gains. Stability of offsets and gain with time or
variations in temperature is excellent. The accuracy and stability
of the OP07, even at high gain, combined with the freedom
from external nulling have made the OP07 an industry standard
for instrumentation applications.
The OP07 is available in two standard performance grades. The
OP07E is specified for operation over the 0°C to 70°C range, and
OP07C over the –40°C to +85°C temperature range.
The OP07 is available in epoxy 8-lead Mini-DIP and 8-lead SOIC.
It is a direct replacement for 725,108A, and OP05 amplifiers;
741-types may be directly replaced by removing the 741’s nulling
potentiometer. For improved specifications, see the OP177 or
OP1177. For ceramic DIP and TO-99 packages and standard
micro circuit (SMD) versions, see the OP77.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the OP07 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

and OP05 sockets with or without removal of external
compensation or nulling components. Additionally, the OP07
may be used in unnulled 741 type sockets. However, if conventional 741 nulling circuitry is in use, it should be modified or
removed to enable proper OP07 operation. OP07 offset voltage
may be nulled to zero through use of a potentiometer (see offset
nulling circuit diagram).
PRECISION ABSOLUTE-VALUE CIRCUIT
The OP07 provides stable operation with load capacitance of
up to 500 pF and ±10 V swings; larger capacitances should be
decoupled with a 50 Q decoupling resistor.
Stray thermoelectric voltages generated by dissimilar metals at
the contacts to the input terminals can degrade drift performance.
Therefore, best operation will be obtained when both input contacts are maintained at the same temperature, preferably close to
the package temperature.
