Precision medium bandwidth signal chains cover a large range of applications that demand accuracy across signal bandwidths from DC to 500 kHz, with sampling rates up to 4 MSPS, such as:

  • Condition-based monitoring (CbM)

  • Power quality monitoring
  • Sensor and system data acquisition

  • Rotation and position sensing
  • Analog input modules for industrial systems

Analog Devices’ precision medium bandwidth signal chains combine precision amplifiers, voltage references, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), circuit protection, and isolation products. They provide measurement and drive control options characterized by 16-bit to 24-bit resolution combined with DC precision and AC signal fidelity. Precise measurement of small and large amplitude signals, measurement and generation of arbitrary signals, or measurement of signals from many inputs at once are key features of these precision medium bandwidth signal chains.

ADI also provides options for high channel-count synchronized systems, designed with consideration for time accuracy and channel-to-channel phase alignment, and options for high channel density by means of small form factor multichannel converters or more highly integrated signal chain blocks (µModule® solutions).
