Analog Devices Inc. has developed the AD629BR-REEL7 Linear Instrumentation Amplifier for use in industrial, medical, and consumer electronic applications. The AD629BR-REEL7 is a single-channel, low-noise operational amplifier (op-amp) designed to provide high-precision signal conditioning. Using the AD629BR-REEL7, a signal’s voltage and current can be amplified or attenuated without adding noise or distortion, making it highly suitable for instrumentation, industrial, and medical applications. This article provides an overview of the AD629BR-REEL7, its working principle, and application field.

Overview of the AD629BR-REEL7

The AD629BR-REEL7 is part of the Analog Devices’ AD629 family, which includes three single-channel and two dual-channel instrumentation amplifiers. The single-channel AD629BR-REEL7 op-amp offers an input common-mode range from 0V to 26V and operates from ±4.5V power supplies with a quiescent current of 1.2mA. The AD629BR-REEL7 op-amp provides a high common-mode voltage gain of 94dB with a large signal bandwidth of 30MHz. It is available in small, 8-pin DIP and SOIC packages.

The AD629BR-REEL7 offers a low input noise voltage of 4 nV/√ Hz, a low offset drift of 3µV/°C, and a low impedance at the input and output. The op-amp is protected against overload and over-temperature conditions, making it suitable for industrial and medical applications. In addition, it has low distortion and harmonic distortion of 0.05% at its full-scale output level.

Working Principle

The AD629BR-REEL7 is a single-channel, low-noise operational amplifier (op-amp) that provides high-precision signal conditioning. It features a non-inverting amplifier that amplifies or attenuates a signal’s voltage and current. The op-amp is designed to maintain a constant gain and decrease noise and distortion. It provides high accuracy with a large signal bandwidth of 30MHz.

The amplifier consists of an input stage, a feedback circuit, and an output stage. The input stage consists of two differential amplifiers, with one amplifier receiving a voltage signal input and the other amplifier receiving an offset voltage. The differential amplifiers amplify the signal and the offset voltage and combine them to form the input. The feedback loop maintains the gain of the amplifier. The output stage combines the signals to form the output of the amplifier.

The AD629BR-REEL7 provides a low-input-noise operational amplifier with high accuracy and a large signal bandwidth. It has two closely matched gain resistors that provide high gain accuracy of ±0.2%. It also offers low DC offset and low input bias current. The op-amp is suitable for use in industrial, medical, and consumer applications.

Application Field

The AD629BR-REEL7 op-amp is suitable for many industrial, medical, and consumer applications. It is an excellent choice for precision signal conditioning and can be used in a wide variety of applications, including medical instruments, industrial test instrumentation, and biomedical applications.
