製品概要The OP270 is a high-performance monolithic dual operational amplifier with exceptionally low voltage noise, offering comparable performance to ADI'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.
