GENERAL DESCRIPTION
The OP270 is a high-performance monolithic dual operational
amplifier with exceptionally low voltage noise, 5n
÷Hz at 1kHz Max,
offering comparable performance to ADI’s industry standard OP27.
The OP270 features an input offset voltage below 75
mV and an
offset drift under 1
mV/∞C,guaranteedoverthefullmilitary tempera-
ture range. Open-loop gain of the OP270 is over 1,500,000 into a
10 k
W load insuring excellent gain accuracy and linearity, even in
high-gain applications. Input bias current is under 20 nA which
reduces errors due to signal source resistance. The OP270’s CMR of
over 106 dB and PSRR of less than 3.2
mV/V significantly reduce
errors due to ground noise and power supply fluctuations. Power
consumption of the dual OP270 is one-third less than two OP27s,
a significant advantage for power conscious applications. The
OP270 is unity-gain stable with a gain bandwidth product of 5 MHz
and a slew rate of 2.4 V/
ms.
The OP270 offers excellent amplifier matching which is important
for applications such as multiple gain blocks, low noise instrumen-
tation amplifiers, dual buffers, and low-noise active filters.
The OP270 conforms to the industry standard 8-lead DIP pinout. It
is pin-compatible with the MC1458, SE5532/A, RM4558, and
HA5102 dual op amps, and can be used to upgrade systems using
these devices.
For higher speed applications the OP271, with a slew rate of 8 V/
ms, is
recommended. For a quad op amp, see the OP470.
