OP270EZ Datasheet

Dual Very Low Noise Precision Operational Amplifier


The OP270EZ is a high performance, monolithic, dual operational amplifier with exceptionally low voltage noise density (5 nV/√Hz maximum at 1 kHz). It offers comparable performance to the industry-standard OP27from Analog Devices, Inc. The OP270EZ features an input offset voltage of less than 75 μV and an offset drift of less than 1 μV/°C, guaranteed over the full military temperature range. Open-loop gain of the OP270 is more than 1,500,000 into a 10 kΩ load, ensuring excellent gain accuracy and linearity, even in high gain applications. The input bias current is less than 20 nA, which reduces errors due to signal source resistance. With a common-mode rejection (CMR) of greater than 106 dB and a power supply rejection ratio (PSRR) of less than 3.2 μV/V, the OP270EZ significantly reduces errors due to ground noise and power supply fluctuations. The power consumption of the dual OP270 is one-third less than two OP27 devices, a significant advantage for power conscious applications. The OP270EZ is unity-gain stable with a gain bandwidth product of 5 MHz and a slew rate of 2.4 V/μs. OP270EZ Features • Very low noise density of 5 nV/√Hz at 1 kHz maximum • Excellent input offset voltage of 75 μV maximum • Low offset voltage drift of 1 μV/°C maximum • Very high gain of 1500 V/mV minimum • Outstanding CMR of 106 dB minimum • Slew rate of 2.4 V/μs typical • Gain bandwidth product of 5 MHz typical
