AD8428BRZ High Precision, Low Power Instrumentation Amplifier by Analog Devices Inc.

The AD8428BRZ is a state-of-the-art instrumentation amplifier from Analog Devices Inc., designed to offer the highest precision and low power consumption for a wide array of industrial and medical applications. This component is renowned for its exceptional accuracy and stability, which is essential for critical measurement tasks.

Encased in a compact SOIC package, the AD8428BRZ features a high gain of 2000 V/V, which is stable over the entire industrial temperature range. This high gain accuracy, combined with a high input impedance, makes it an ideal choice for small signal amplification, ensuring that the integrity of the signal is maintained without significant loading of the source.

The device boasts an impressive low input noise density of only 1 nV/√Hz at 1 kHz, which minimizes the impact of extraneous noise on signal quality. Additionally, the AD8428BRZ has a low total harmonic distortion (THD) that ensures the amplified signal remains true to the original, a critical feature for high-fidelity applications.

With a wide supply voltage range from ±4 V to ±18 V, the AD8428BRZ offers flexibility in system design. This range allows it to be used in both low-voltage and high-voltage applications without compromising performance. The quiescent current is also remarkably low, at only 4 mA maximum, which is beneficial for battery-powered or energy-efficient systems.

One of the key features of the AD8428BRZ is its high common-mode rejection ratio (CMRR) of 130 dB min at G = 2000, which is maintained over a wide frequency range. This characteristic is crucial for applications where common-mode noise can be a significant issue, such as in industrial control systems or precision data acquisition.

To ensure reliability and durability, the AD8428BRZ is designed to operate over the extended industrial temperature range of -40°C to +125°C. Its robust design and superior performance make it an excellent choice for demanding environments where precision and reliability are paramount.

Whether it's for use in precision instrumentation, medical equipment, strain gage amplifiers, or industrial process controls, the AD8428BRZ from Analog Devices Inc. stands out as a high-performance solution that can meet the rigorous demands of high precision amplification.
