AD622 - Low Cost Instrumentation Amplifier

General Description

The AD622 is a low cost, moderately accurate instrumentation amplifier that requires only one external resistor to set any gain between 2 and 1,000.

Or for a gain of 1, no external resistor is required.

Key Features

  • Easy to Use Low Cost Solution Higher Performance than Two or Three Op Amp Design Unity Gain with No External Resistor Optional Gains with One External Resistor (Gain Range 2 to 1000) Wide Power Supply Range (؎ 2.6 V to ؎15 V) Available in 8-Lead PDIP and SOIC Low Power, 1.5 mA max Supply Current GOOD DC.
