Low Cost, Zero Drift Instrumentation Amplifier Ideal for Maximum Channel Density in Space Critical Designs

The AD8293 is an affordable, small form factor, precision instrumentation amplifier that has low noise and rail-to-rail output. The device incorporates gain setting and filter resistors, reducing the number of ancillary components needed in a design. The AD8293 also features low offset voltage, offset drift, and gain drift coupled with high common-mode rejection. It is specified over the industrial temperature range from –40°C to +85°C and is available in a halogen- free, Pb-free, 8-lead SOT-23 package.
