AD8228BRZ-R7

AD8228BRZ-R7 is a low-gain drift, high-performance instrumentation amplifier with 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. It operates on both single and dual supplies. Because the part can operate on supplies upto ±18V, it is well-suited for applications where high common-mode input voltages are encountered. It is used in applications such as weigh scales, industrial process controls, bridge amplifiers, precision data acquisition systems, medical instrumentation, strain gages, and transducer interfaces.
