GENERAL DESCRIPTION
The AD8500 is a low power, precision CMOS op amp featuring
a maximum supply current of 1 μA. The AD8500 has a maximum
offset voltage of 1 mV and a typical input bias current of 1 pA; it
operates rail-to-rail on both the input and output. The AD8500
can operate from a single-supply voltage of +1.8 V to +5.5 V or
a dual-supply voltage of ±0.9 V to ±2.75 V.
With its low power consumption, low input bias current, and
rail-to-rail input and output, the AD8500 is ideally suited for
a variety of battery-powered portable applications. Potential
applications include ECGs, 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 the AD8500 to be used in systems with high gain without
having excessively large output offset errors, and it provides
high accuracy without the need for system calibration.
The AD8500 is fully specified over the industrial temperature
range (40°C to +85°C) and is operational over the extended
industrial temperature range (40°C to +125°C). It is available
in a 5-lead, SC70 surface-mount package.
