Description
The AD8421ARMZ is an instrumentation op-amp that provides low-power signal amplification and conditioning for data acquisition in various applications. It features ultra-low bias current, high common-mode rejection ratio (CMRR), and excellent distortion performance, making it ideal for use in precision instrumentation systems, such as medical instrumentation, microphone preamplification, and vibration analysis.
Specifications and Features
- Inputs protected up to 40 V from opposite supply
- Dual supply voltage range of ±2.5 V to ±18 V, or a single supply range of 5 V to 36 V
- Gain set with a single resistor with a range of 1 to 10,000
- Low power consumption with a maximum supply current of 2.3 mA
- Low noise with 3.2 nV/√Hz maximum input voltage noise at 1 kHz and 200 fA/√Hz current noise at 1 kHz
- Wide bandwidth of 10 MHz at G = 1 and 2 MHz at G = 100
- Slew rate of 35 V/μs
- Settling time of 0.6 μs to 0.001% at G = 10
- High CMRR of 80 dB at 20 kHz and excellent distortion performance
- Maximum input offset voltage drift of 0.2 μV/°C and gain drift of 1 ppm/°C (G = 1)
- Maximum input bias current of 500 pA
Application Scenarios
The AD8421ARMZ is commonly used in precision data acquisition systems, medical devices, microphone preamplification, and multiplexed input applications. It is also suitable for vibration analysis, which requires high-speed signal amplification and low noise in demanding applications.
Comparison
Advantages- Low bias current and excellent CMRR for accurate signal extraction and conditioning
- Wide bandwidth and high slew rate for high-speed signal amplification
- Low offset voltage drift and gain drift for precise data acquisition
- Low power consumption and low noise
Disadvantages- The product is designed to be an instrumentation amplifier, therefore, it might not be as versatile as some general-purpose op-amps
