GENERAL DESCRIPTION

Figure 2. 14-Lead TSSOP (RU-14)

The AD850x family are low power, precision CMOS op amps

featuring a maximum supply current of 1 μA. The AD850x family

has a maximum offset voltage of 3 mV and a typical input bias

current of 1 pA, and it operates rail-to-rail on both the input

and output. The AD850x family 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 AD850x family 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 the AD850x family 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 AD850x family 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). The

AD8502 is available in a 8-lead, SOT23 surface-mount package.

The AD8504 is available in 14-lead TSSOP surface-mount

package.
