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 mV/∞C, guaranteed over the full military temperature range. Open-loop gain of the OP270 is over 1,500,000 into a 10 kW 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 stabl……
