GENERAL DESCRIPTION

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 low power, precision CMOS operational

amplifiers featuring a maximum supply current of 1 μA. 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.ꢀ V to 2.ꢁ5 V.

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.

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.
