The AD8504ARUZ is a low power precision quad CMOS Operational Amplifier for use with low power filters. The AD8504 has a maximum offset voltage of 3mV and a typical input bias current of 1pA operating rail-to-rail on both the input and output. With its low power consumption, low input bias current and rail-to-rail input and output, the AD8504 is ideally suited for a variety of battery-powered portable applications. Potential applications include bedside monitors, pulse monitors, glucose meters, smoke and fire detectors, vibration monitors and backup battery sensors. The ability to swing rail-to-rail at both the input and output helps maximize dynamic range and signal-to-noise ratio in systems that operate at very low voltages. The low offset voltage allows use of the AD8504 in systems with high gain without creating excessively large output offset errors. The AD8504 offers an additional benefit by providing high accuracy without the need for system calibration.
