AD8421 Amplifier Module Instrumentation Amplifier Millivolt Microvolt Small Signal With Shielding Box
1. The AD8421 is a low cost, low power, extremely low noise, ultralow bias current, high speed instrumentation amplifier that is perfect suited for a broad spectrum of signal conditioning and data acquisition applications. This product features extremely high CMRR, allowing it to extract low level signals in the presence of high frequency common-mode noise over a wide temperature range.
2. The 10 MHz bandwidth, 35 V/μs slew rate, and 0.6 μs settling time to 0.001% (G = 10) allow the AD8421 to amplify high speed signals and excel in applications that require high channel count, multiplexed systems. Even at higher gains, the current feedback architecture maintains high performance; The AD8421 has excellent distortion performance, making it suitable for use in demanding applications such as vibration analysis.
3. The AD8421 delivers 3 nV/√Hz input voltage noise and 200 fA/√Hz current noise with only 2 mA quiescent current, making it a perfect choice for measuring low level signals. For applications with high source impedance, the AD8421 employs innovative process technology and design techniques to provide noise performance that is limited only by the sensor.
4. The AD8421 uses unique protection methods to ensure robust inputs while still maintaining very low noise. This protection allows input voltages up to 40 V from the opposite supply rail without damage to the part. A single resistor sets the gain from 1 to 10,000. The reference pin can be used to apply a precise offset to the output voltage.
5. The AD8421 is specified from −40Celsius to 85Celsius and has typical performance curves to 125Celsius. It is available in 8-lead MSOP and SOIC packages.
