AD8603AUJZ-REEL

AD8603AUJZ-REEL is a single channel, micropower rail-to-rail input and output amplifier. It features very low offset voltage as well as low input voltage and current noise. This amplifier uses a patented trimming technique that achieves superior precision without laser trimming. The parts are fully specified to operate from 1.8V to 5V single supply or from ±0.9V to ±2.5V dual supply. The combination of low offsets, low noise, very low input bias currents, and low power consumption makes the device especially useful in portable and loop-powered instrumentation. The ability to swing rail to rail at both input and output enables designers to buffer CMOS ADCs, DACs, ASICs, and other wide output swing devices in low power, single-supply systems. It is used in applications such as battery-powered instrumentation, multipole filters, sensors, low power ASIC input or output amplifiers.
