GENERAL 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

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 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
