GENERAL DESCRIPTION
The AD8502/AD8504 are low power, precision CMOS operational
amplifiers featuring a maximum supply current of 1 μA per
amplifier. The AD8502/AD8504 have a maximum offset voltage
of 3 mV and a typical input bias current of 1 pA operating rail-
to-rail on both the input and output. The AD8502/AD8504 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 AD8502/AD8504 are 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 AD8502/AD8504 in systems with high gain
without creating excessively large output offset errors. The
AD8502 and AD8504 offer an additional benefit by providing
high accuracy without the need for system calibration.
The AD8502/AD8504 are fully specified over the industrial
temperature range (40°C to +85°C) and the extended indus-
trial temperature range (40°C to +125°C). The AD8502 is
available in an 8-lead, SOT-23 surface-mount package. The
AD8504 is available in a 14-lead TSSOP surface-mount package.
