General Description

The AD8228 is a high performance instrumentation amplifier with very high gain accuracy.

Because all gain setting resistors are internal and laser trimmed, gain accuracy and gain drift are better than can be achieved with typical instrumentation amplifiers.

Low voltage offset, low offset drift, low gain drift, high gain accuracy, and high CMRR make this part an excellent choice in applications that demand the best dc performance possible, such as bridge signal conditioning.
