BU7295SHFV-TR: Application Field and Working Principle

Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

The BU7295SHFV-TR is an instrumentation-grade operational amplifier (OP Amp) and buffer amplifier designed for flexibility and optimal performance in increasing the signal quality and accuracy of industrial instrumentation and control applications in medical, automotive, telecom, industrial, and scientific fields. Besides, the device is capable of ultra-high common-mode rejection ratio (CMRR).The BU7295SHFV-TR is particularly suited for applications that require the highest common-mode rejection ratio, along with high accuracy and stability. Some applications are two-wire systems, high input impedance analog-to-digital converters (ADC), high dynamic range amplifiers, instrumentation-grade precision amplifiers, direct-coupled amplifiers, and low noise motor drives and motion control systems.

Working Principle

The BU7295SHFV-TR has a pair of differential inputs, each with a low-impedance input stage, to ensure fast response and high accuracy. The device is designed to resist common-mode interference and provides an amplified signal with a frequency response of 0.04 kHz to 55 kHz.The BU7295SHFV-TR uses a combination of capacitors and resistors to achieve the highest common-mode rejection ratio. The internal voltage gain of the device is determined by the feedback loop which consists of three resistors and two capacitors, while the dynamic range of the amplifier is limited by the resistor-capacitor network.The vast majority of devices in the series feature an offset voltage ranging from 1.2 to 3.0 mV and a common-mode rejection ratio of 70 to 75 dB.
