GENERAL DESCRIPTION

The OP271 is a unity-gain stable monolithic dual op amp
featuring excellent speed, 8.5 V/ms typical, and fast settling
time, 2 ms typical to 0. 01%. The OP271 has a gain bandwidth
of 5 MHz with a high phase margin of 62∞.
Input offset voltage of the OP271 is under 200 mV with input
offset voltage drift below 2 mV/∞C, guaranteed over the full
military temperature range. Open-loop gain exceeds 400,000
into a 10 kW load ensuring outstanding gain accuracy and
linearity. The input bias current is under 20 nA limiting
errors due to source resistance. The OP271’s outstanding
CMR, over 106 dB, and low PSRR, under 5.6 mV/V, reduce
errors caused by ground noise and power supply fluctuations.
In addition, the OP27l exhibits high CMR and PSRR over a
wide frequency range, further improving system accuracy.

OP271
CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V 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.
(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.

NOTESAbsolute maximum ratings apply to packaged parts, unless otherwise noted.The 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.�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.
