The OP270 is a high performance, monolithic, dual operational
amplifier with exceptionally low voltage noise density (5 nV/√Hz
maximum at 1 kHz). It offers comparable performance to the
industry-standard OP27 from Analog Devices, Inc. consumption of the dual OP270 is one-third less than two OP27
devices, 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/μs. The OP270 features an input offset voltage of less than 75 μV
and an offset drift of less than 1 μV/°C, guaranteed over the full
military temperature range. Open-loop gain of the OP270 is more
than 1,500,000 into a 10 kΩ load, ensuring excellent gain accuracy …
