OP270 Description

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.

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 and linearity, even in high gain applications. The input bias current is less than 20 nA, which reduces errors due to signal source resistance. With a common-mode rejection (CMR) of greater than 106 dB and a power supply rejection ratio (PSRR) of less than 3.2 μV/V, the OP270 significantly reduces errors due to ground noise and power supply fluctuations. The power 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 offers excellent amplifier matching, which is important for applications such as multiple gain blocks, low noise instrumentation amplifiers, dual buffers, and low noise active filters.

The OP270 conforms to the industry-standard 8-lead CERDIP and PDIP pinouts.
