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.

The AD8228 operates on both single and dual supplies. Because the part can operate on supplies up to ±18 V, it is well suited for applications where high common-mode input voltages are encountered. The AD8228 is available in 8-lead MSOP and SOIC packages.

Performance is specified over the entire industrial temperature range of −40°C to +85°C for all grades. Furthermore, the AD8228 is operational from −40°C to +125°C. For a pin-compatible amplifier with similar specifications, but with a gain range of 1 to 1000, see the AD8221.

APPLICATIONS

  • Weigh scales
  • Industrial process controls
  • Bridge amplifiers
  • Precision data acquisition systems
  • Medical instrumentation
