OP270:  Low Noise Precision Dual Op Amp

Product Details


Newer Alternatives:
  • AD8672 with improved DC accuracy, noise, speed and quiescent power consumption in narrow SOIC and MSOP 8-Lead packages.

The OP270 is a high-performance monolithic dual operational amplifier with exceptionally low voltage noise, 5nV/(root)Hz at 1kHz Max, offering comparable performance to PMI's industry standard OP27.

The OP270 features an input offset voltage below 75µV and offset drift under 1µV/°C, guaranteed over the full military temperature range. Open-loop gain of the OP270 is over 1,500,000 into a 10k Ohm load insuring excellent gain accuracy and linearity, even in high-gain applications. Input bias current is under 20nA which reduces errors due to signal source resistance. The OP270's CMR of over 106dB and PSRR of less than 3.2µV/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 concious applications. The OP270 is unity-gain stable with a gain-bandwidth product of 5MHz and a slew rate of 2.4V/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-pin DIP pinout. It is pin compatible with the MC1458/1558, SE5532/A, RM4558, and HA5102 dual op amps and can be used to upgrade systems using these devices.

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