AD8221AR Programmable MSOP Precision Instrumentation Amplifier Module Gain Board
The AD8221AR is a gain programmable, high-performance instrumentation amplifier with the highest common mode rejection ratio (CMRR) relative to frequency in the industry. In today's market, CMRR of instrumentation amplifiers decays at 200 Hz. In contrast, the CMRR of all grades of the AD8221 is maintained at a minimum of 80 dB at G = 1 and at frequencies up to 10 kHz. The high common mode rejection ratio (CMRR) relative to the frequency allows the CJMCU-8221 to reject wideband interference and linear harmonics, greatly simplifying the filtering requirements. Possible applications include precision data acquisition, biomedical analysis and aerospace instrumentation. 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. Programmable gain gives the user design flexibility. Through a resistor, gain can be set in the range of 1 to 1000. 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 ° C to + 85 ° C for all ratings. In addition, the AD8221 can operate from -40 ° C to + 125 ° C *.
