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.

Tools & Simulations
In-Amp Diamond Plot Tool
The Diamond Plot Tool is a web application that generates a configuration-specific Output Voltage Range vs. Input Common-Mode Voltage graph, also known as the Diamond Plot, for Analog Devices Instrumentation Amplifiers. Based on user inputs such as supply voltage, gain, and input signal range, the tool detects saturation and recommends in-amps for which the input signal is in-range and the configuration is valid. Avoid saturation, find the best in-amp for your design, and save time.

Signal Chain Designer - BETA
Signal Chain Designer is a web-based tool designed to create and simulate complex precision signal chains. See your circuit’s performance before you commit to your PCB: transfer function, noise, power consumption, input range, and DC error. Quickly experiment with different parts and architectures. Signal chains can be exported to LTspice for further analysis.
