GENERAL DESCRIPTION
The OP270 is a high performance, monolithic, dual operational
amplifier with exceptionally low voltage noise, 5 nV/÷Hz max at
1 kHz. It offers 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, guaranteed over the full military tem-
perature range. Open-loop gain of the OP270 is over 1,500,000
into a 10 kW load, ensuring 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 signifi-
cantly 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.

SIMPLIFIED SCHEMATIC
BIAS
The OP270 offers excellent amplifier matching, which is important
for applications such as multiple gain blocks, low noise instru-
mentation 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 those 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.
