OP270 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 V/⁰C, guaranteed over the full military temperature range. Open-loop gain of the OP270 is over 1,500,000 into a 10 k 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 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/s.

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 OP271, with a slew rate of 8 V/s, is recommended. For a quad op amp, see the OP470.

NOTES
1 Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
2 The OP270's inputs are protected by back-to-back diodes. Current limiting resistors are not used, in order to achieve low noise performance. If differential voltage exceeds +10 V, the input current should be limited to ±25 mA.
