High-Speed, Dual Operational Amplifier

Analog Devices 

OP271

(Continued from Page 1)

The OP271 offers outstanding dc and ac matching between chan-

nels. This is especially valuable for applications such as multiple

gain blocks, high-speed instrumentation and amplifiers, buffers

and active filters.

The OP271 conforms to the industry standard, 8-pin dual op amp

pinout. It is pin compatible with the TL072, TL082, LF412,

and 1458/1558 dual op amps and can be used to significantly

improve systems using these devices.

For applications requiring lower voltage noise, see the OP270.

For a quad version of the OP271, see the OP471.

NOTES

1Absolute maximum ratings apply to packaged parts, unless otherwise noted.

2The OP271’s inputs are protected by back-to-back diodes. Current limiting

resistors are not used in order to achieve low-noise performance. If differential

voltage exceeds ± 1.0 V, the input current should be limited to ± 25 mA.

3␪jA is specified for worst case mounting conditions, i.e., ␪jA is specified for

device in socket for CERDIP and P-DIP packages; ␪jA is specified for device

soldered to printed circuit board for SOIC package.

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 OP271 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.
