The AD620BR is a low cost, precision monolithic instrumentation amplifier with a differential input stage, single-ended output, and nonlinearity voltage gain of 5V/V. This device has wide bandwidths, high common-mode rejection ratios (CMRRs), low power dissipation, and low offset. In addition, the AD620BR amplifier offers a low input bias current and an adjustable common-mode range. These features make the AD620BR a great choice for use in high accuracy instrumentation, medical, and industrial applications.
Application Field
The AD620BR is suited for a wide range of instrumentation and control applications. This device is an ideal choice for amplifier designs requiring precision, small size, low power consumption, low input bias current, and high resolution. It can be used for medical and test equipment control systems, data acquisition, audio circuitry, and video circuit designs. In addition, the AD620BR amplifier is used in industrial applications due to its high CMRR, linearity, and driven-point accuracy.
Working Principle
The AD620BR instrumentation amplifier works by providing a differential input with a single-ended output. This allows it to accurately measure minute voltage differences between two input terminals. The amplifier has a precision, linear differential amplifier at the front end that provides an input gain of 4V/V. The output of this amplifier is then amplified by a single-ended amplifier section before being provided to the output stage. The single-ended amplifier has a gain adjustment from 2V/V to 5V/V, thus allowing for flexibility in the amplification of very small signals. The Vos offset voltage is controlled by an external voltage and is typically between 500uV and 1mV. The AD620BR can also have an adjustable common-mode range for customizing the maximum input and reducing common-mode noise. Additionally, this device includes a low power-on reset feature and a low input bias current of 3nA.
Summary
The AD620BR is designed to provide optimal performance in a wide range of instrumentation applications. This device features low nonlinearity, an adjustable gain range, low input bias, and high CMRR. The AD620BR is an excellent choice for instrumentation, test equipment, and industrial applications that require a reliable and accurate amplifier. It provides superior performance in noise-free environments and requires minimal power for operation.
