## Features

- The AD8221AR is a gain programmable, high-performance instrumentation amplifier with the highest common mode rejection ratio (CMRR) relative to frequency in the industry.
- Low-voltage offset, low offset drift, low gain drift, high gain accuracy, and high common-mode rejection ratio make this device an excellent choice for applications requiring optimal dc performance, such as bridge signal conditioning.
- The CJMCU-8221 can be operated from a single or dual supply, making it ideal for applications where the input voltage is 10 V.
- The device is rated over the industrial temperature range of -40 ℃ to + 85℃ for all ratings. In addition, the AD8221 can operate from -40 ℃ to + 125 ℃ .
- Programmable gain gives the user design flexibility. Through a resistor, gain can be set in the range of 1 to 1000.
