ADA4091-2ACPZ-R7

The ADA4091-2ACPZ-R7 is a precision low power instrumentation amplifier from Analog Device’s Shockley series. It features a wide bandwidth and low offset voltage. It is ideal for both single-ended and differential input data acquisition applications. It is typically used for low voltage precision preamplification applications. The ADA4091-2ACPZ-R7 is an ideal choice for applications such as bridge amplifiers, transducer conditioning, thermocouple buffers, and low voltage motor control systems.

The basic operating principle of the ADA4091-2ACPZ-R7 is that of an inverter amplifier. It is composed of two amplifying stages. The first stage amplifies the input signal and the second stage amplifies and reverses the direction of the signal. The output is then determined by the second stage. This type of amplifier is commonly used in instrumentation applications because it provides extremely low power characteristics, high accuracy and isolation, large bandwidth and a high input impedance.

The chip is designed to be powered by a single 1.8V to 5.5V supply, allowing it to operate efficiently in low voltage applications. The device is available in an 8-lead MSOP package and is optimized for low power operation with a quiescent current of only 4µA. It is rated for a maximum supply current of 10mA and a maximum output voltage swing of 10V.

The ADA4091-2ACPZ-R7 includes several features ideal for low power applications. It has an adjustable common-mode voltage range, adjustable gain ranges from 0.5 to 20V/V, and a low input bias current of 1nA. The device also features a low input offset voltage of 50µV, ensuring excellent DC accuracy and precision.

Its low noise characteristics make it perfect for applications that require low levels of noise. The ADA4091-2ACPZ-R7 can operate at low frequencies, making it ideal for data acquisition applications. It is also capable of handling very high input voltage swings without saturating or distorting the output.

Thehigh accuracy and low offset voltage of the ADA4091-2ACPZ-R7 makes it ideal for applications that require a high level of precision. Its large bandwidth and low power operation make it perfect for a wide variety of instrumentation, motor control, and other applications.
