OP270GPZ: 运算放大器PDIP-8封装
The OP-270 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 OP-27.
The OP-270 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 OP-270 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 OP-270'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 OP-270 is one-third less than two OP-27s, a significant advantage for power concious applications. The OP-270 is unity-gain stable with a gain-bandwidth product of 5MHz and a slew rate of 2.4V/µs.
The OP-270 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 OP-270 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 OP-271, with a slew rate of 8V/µs, is recommended. For a quad op amp, see the OP-470.
