Product Overview

The AD8428ARZ is a Low Noise Low Gain Drift Instrumentation Amplifier designed to accurately measure tiny, high speed signals. All gain setting resistors for the amplifier are internal to the part and are precisely matched. Care is taken in both the chip pinout and layout. This results in excellent gain drift and quick settling to the final gain value after the part is powered on. The high CMRR prevents unwanted signals from corrupting the signal of interest. The pinout is designed to avoid parasitic capacitance mismatches that can degrade CMRR at high frequencies. This is one of the fastest instrumentation amplifiers available. The circuit architecture is designed for high bandwidth at high gain. The pinout allows access to internal nodes between the first and second stages. This feature can be useful for modifying the frequency response between the two amplification stages, thereby preventing unwanted signals from contaminating the output results.
  • Fixed gain of 2000
  • Access to internal nodes provides flexibility
  • 1.5nV/√Hz Input voltage noise
  • High accuracy DC performance
  • 5ppm/°C Gain drift
  • 0.3µV/°C Offset drift
  • 0.05% Gain accuracy
  • 5000V (HBM) ESD protection

Applications

Sensing & Instrumentation, Medical, System Monitoring

Warnings
