AD8502ARJZ-REEL7 精密放大器

AD8502ARJZ-REEL7

精密放大器 1 μA Micropower CMOS  Operational Amplifiers

GENERAL DESCRIPTION AD8502ARJZ-REEL7

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 railto-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.
