AD8091ARZ Application Field and Working PrincipleAs a high performance, low power, and rail-to-rail output, single-supply precision CMOS amplifier, AD8091ARZ is an ideal building block for wide range of industrial, consumer, medical, and general purpose applications.AD8091ARZ has excellent AC and DC characteristics, and its low quiescent current and wide common-mode and power supply operation ranges make it suitable for low power hand-held and battery-powered instruments, as well as low voltage signal processing systems. With a fully-differential input stage, excellent output drive capability, and a no-latency shutdown mode, the AD8091ARZ is a perfect choice for instrumentation amplifiers and active analog signal conditioning circuits.Definition of Instrumentation AmplifiersInstrumentation amplifiers (also known as “in-amps”) are special, precise amplifiers characterized by high open-loop gain, low noise, low distortion, wide frequency response, and high input impedance. They are designed to accept small differential signals from a transducer or sensor, amplify them, and provide an isolated and accurate output.In-amps are commonly used in industrial instrumentation, motion sensing and control systems, precision voltage sensing circuits, and other applications. Since in-amps are accurate, reliable, and robust amplifiers, they have become increasingly popular in a wide range of practical and demanding applications.The Working Principle of AD8091ARZAD8091ARZ is a precision CMOS amplifier that includes a low offset, high impedance fully-differential input stage and a high current output amplifier. It is a high-performance, low-power, rail-to-rail output device. It has a wide common-mode input range (0V to +3V) and can operate on a single supply voltage (3V to 7V).The high open-loop gain of AD8091ARZ provides excellent linearity and accuracy, even at very low signal levels. It also has excellent AC and DC characteristics with a fast settling time and low noise. Its low quiescent current together with the high output voltage swing make it an ideal amplifier for low-power precision applications.The input stage of the AD8091ARZ includes a low offset, high impedance and fully differential input amplifier. The differential amplifier is connected between the two support pins, negative (VCOM-) and positive (VCOM+), providing high common-mode rejection and low noise.The differential amplifier is followed by two voltage followers whose outputs are connected to the power supply rails (VSS and VSS). The followers together with the common-mode capacitor in the input stage amplify the input signal with a gain of approximately unity and provide excellent common-mode rejection. The output of the input stage is then applied to the output voltage amplifier whose non-inverting input is connected to the output stage.The output voltage amplifier also provides a low offset, high impedance, rail-to-rail output with excellent linearity and low distortion. When the device is in shutdown mode, the output voltage is held either at VCC or GND, and the amplifier current is completely eliminated. This makes the AD8091ARZ suitable for low power applications, such as battery-powered instruments. The output voltage amplifier is capable of driving a wide range of capacitive, resistive, and inductive loads.ConclusionAD8091ARZ is a highly-accurate, low-power CMOS precision amplifier, suitable for a wide range of industrial and consumer applications. Its wide common-mode input range and excellent output drive capability make it ideal for instrumentation amplifiers and active analog signal conditioning circuits. The combination of low offset, high impedance, low power consumption, and rail-to-rail output make it ideal for low power hand-held or battery-powered instruments. The accuracy and low distortion of the AD8091ARZ make it an excellent choice for precision sensing and motion control applications.
