The AD8602AR is a low power, low voltage, high performance, wide bandwidth instrumentation amplifier created by Analog Devices. It is part of the AR series of instrumentation amplifiers, which are designed to simplify circuit design in a range of applications that benefit from high common-mode rejection, such as strain gauge, biomedical, data acquisition, and precision industrial control systems. This instrumentation amplifier has a range of features that make it ideal for applications such as medical devices, industrial process monitoring and control, and audio systems.

The AD8602AR is a precision instrumentation amplifier constructed from three high performance op amps, two amplifiers which act as the inverting and non-inverting inputs, and one summing amplifier. It has a CMRR of 128 dB at 1 kHz, a DC offset of 3 μV, and a wide supply voltage range of 2.7V to 12V. It also includes an active-low power-down pin that can be used to disable the amplifier when not in use.

The AD8602AR’s internal gain setting resistors can be used to set the gain of the amplifier from 1 to 1000. Additionally, the gain can be adjusted through the external gain set pin, allowing users to set the gain independently of the traditional internal resistor values. For applications that require a higher level of accuracy and stability, the AD8602AR offers a temperature compensated gain block that can be used to reduce the effects of temperature drift.

The AD8602AR is designed to operate optimally when operating within a single-supply operating range from 2.7V to 12V. It also has a rail-to-rail output stage and can operate from symmetric dual supplies of up to ±12V. This instrumentation amplifier also includes a quiescent current of only 50μA and an input bias current of only 2μA, making it power efficient and suitable for portable applications.

The AD8602AR is a versatile instrumentation amplifier suited for many applications due to its high input impedance, low power consumption, small size, and wide bandwidth. It is well suited for applications such as strain gauge, medical instrumentation, signal processing, and data acquisition. Moreover, its features make it ideal for use in signal conditioning, precision amplification, and filtering.

In summary, the AD8602AR is a high performance, low power, low voltage instrumentation amplifier created by Analog Devices. It is well suited for a variety of applications where high common-mode rejection and low power consumption are needed, such as medical devices, industrial process monitoring and control, and audio systems. The AD8602AR includes an active-low power-down pin for power saving, a range of gain settings from 1 to 1000, and a temperature compensated gain block to reduce the effects of temperature drift. Its small size and wide bandwidth make it suitable for use in signal conditioning, precision amplification, and filtering.
