The AD8027ARTZ-REEL is an analog integrated circuit that can be used as a linear amplifier in an instrumentation system. This device is a dual-channel buffer/amplifier with a slew rate of ±100 V/µs and supply voltage of +2.7V to +5.5V. As one of many of Analog Devices’ instrumentation amplifiers, the AD8027ARTZ-REEL has a wide range of applications in a variety of fields, notably the medical, industrial and aerospace markets.

The AD8027ARTZ-REEL operates on a single positive supply, providing low-noise, high-precision amplification of very small signals. Its features, such as temperature compensated supply voltage, wide frequency range and low offset voltage, make it an excellent choice for applications requiring low-noise, high-precision amplification. Its low offset, high gain accuracy and low power consumption make it an ideal choice for battery-powered systems. Its small footprint and high bandwidth make it suitable for a variety of electronic instrumentation and filter applications.

The AD8027ARTZ-REEL utilizes a sophisticated design that allows for both high-precision and low-power operation. The device contains two independent, power-matched amplifiers, each with a low-noise output stage to reduce crosstalk and supply noise. The input stage uses a differential amplifier topology to reject common-mode signals, while its high-speed output stage includes a programmable transconductance amplifier to provide high-bandwidth, low-distortion amplification of the input signal. The output stage also includes a low-noise differential amplifier to further minimize distortion. A unity-gain output buffer provides high-speed rise time, low noise and low offset voltage.

The AD8027ARTZ-REEL works by amplifying a differential input signal by a factor of two with low noise and high accuracy. It is important to note that the input signal must be within its power supply rail range; maximum input swing ranges from 0.83V to 2.7V for a single +3.3V supply. To reduce power consumption and increase bandwidth, it is recommended to use lower rail voltages. The gain of the device is determined by the transimpedance of the input stage and is set by the resistor connected to pins 4 and 5. The output signal is then processed by the output stage, which is capable of driving up to two loads without distortion.

The AD8027ARTZ-REEL is well-suited for applications such as medical device signal processing, high-precision filtering, measurement instrumentation, and signal conditioning. Its small size, wide frequency range and low power consumption make it an excellent choice for high-performance and lower power battery-operated systems. Its high-precision, low-noise circuitry make it a popular choice for critical measurement systems.
