The LT1281AISW#PBF is a dual low-noise operational amplifier from Analog Devices. It has low voltage noise performance, wide bandwidth and rail-to-rail input and output. It features rail-to-rail input and output capability, very low offset voltage, offset voltage drift and drift in power supply current. The LT1281 is ideal for high gain buffer applications and for extremely precise and low noise precision circuits. This device operates from a single +3V to +20V power supply and has a typical unity gain bandwidth of 950kHz with a gain of 2. Additionally, it features very low noise levels, up to -85dBV, with a typical input noise voltage of 4nV and input current noise of 0.006pA. The LT1281AISW#PBF is specified for operation over the extended temperature range of -40°C to 125°C, is available in 8-lead PDIP, SOIC and SOT-23 surface-mount packages, and is RoHS compliant.
