AD8221ARMZ-R7 Instrumentation Amplifier
The AD8221ARMZ-R7 is a precision, low-noise instrumentation amplifier from Analog Devices, designed to amplify small differential signals in the presence of large common-mode noise. It offers exceptional accuracy, high common-mode rejection (CMR), and wide power supply range, making it ideal for demanding measurement applications. The device features a single external resistor for setting gains from 1 to 1000, providing flexibility and ease of use. Its robust performance and integrated design eliminate the need for complex discrete amplifier circuits, serving as a core component in industrial, medical, and scientific instrumentation where signal integrity is paramount.
This instrumentation amplifier operates from dual power supplies of ±2.3 V to ±18 V or a single supply of 2.6 V to 36 V. It provides a high common-mode rejection ratio of 90 dB minimum at a gain of 10 (120 dB at G=1000), effectively rejecting interference. Key specifications include a low input offset voltage of 60 µV (maximum), low input offset drift of 0.4 µV/°C, and low input voltage noise of 8 nV/√Hz. The device has a bandwidth of 800 kHz at a gain of 1, adjustable via the gain resistor.
