The AD8421BRZ-R7 is a high-performance instrumentation amplifier from Analog Devices Inc., designed to deliver precision, low noise, and high gain accuracy. This product is optimized for medical applications, industrial controls, and precision data systems where tight signal conditioning is required.

Key Features

• High Gain Accuracy: The AD8421BRZ-R7 offers a gain accuracy of ±0.25% for gains of 1 to 10,000, ensuring precise amplification of input signals.
• Low Noise: With a low input noise of 1 nV/√Hz at 1 kHz, this amplifier is ideal for applications requiring a clean signal amplification.
• Wide Bandwidth: It provides a 3-dB bandwidth of 10 MHz (G = 1), allowing it to handle a wide range of frequencies without distortion.
• High CMRR: The common-mode rejection ratio (CMRR) is greater than 80 dB for G = 1, which means the amplifier can effectively minimize noise and interference present in the common-mode signal.
• Low Power Consumption: The device operates with a quiescent current of 4 mA, making it suitable for battery-powered devices and portable applications.
