ALD2701SBL

Overview

The ALD2701SBL is a dual monolithic CMOS micropower operational amplifier manufactured by Advanced Linear Devices, Inc. It features rail-to-rail input and output voltage ranges, allowing operation with signals equal to the supply rails. The device operates on single supplies from +2V to +10V or dual supplies from ±1V to ±5V. Key electrical characteristics include a unity gain bandwidth of 0.7MHz, a slew rate of 0.7V/µs, and an extremely low typical input bias current of 1.0pA. It offers high open-loop voltage gain and is designed for low power dissipation.
