The AD8226 is a low cost instrumentation amplifier that requires only one external resistor to set any gain between 1 and 1000. The amplifier has a wide power supply range and high output voltage, making it suitable for use in industrial process controls, bridge amplifiers, medical instrumentation, portable data acquisition, and multichannel systems.
The AD8226 is a low‑cost instrumentation amplifier that requires only one external resistor to set a gain between 1 and 1000. It offers a very wide supply range, rail‑to‑rail output, and input over‑drive protection, making it suitable for industrial process controls, bridge amplifiers, medical instrumentation, portable data acquisition, and multichannel systems.
The device is offered in three grades (A, B, C) covering temperature ranges from –40 °C up to +125 °C, and is available in SOIC‑8 and MSOP‑8 packages. Its specifications include high bandwidth, low noise, and low quiescent current, enabling space‑constrained, low‑power, multichannel applications.
