Precision Signal Analyzers

Signal analysis instruments perform time-domain and frequency-domain analysis to evaluate signal properties, study mechanical vibrations, analyze power quality, and perform non-destructive testing (NDT). They are capable of generating high-quality signals to be used as excitation and reference, and they can perform Fourier transforms and other signal-processing algorithms in real-time. To meet the bandwidth and dynamic-range requirements for this class of instruments, Analog Devices offers:

  • The industry’s highest dynamic range A/D converters
  • The lowest distortion and lowest noise amplifiers for high-fidelity signal conditioning
  • Floating-point digital signal processors for real-time signal analysis

With the highest performance mixed-signal processing portfolio, ADI continues to enable innovation in precision signal analysis.

Evaluation Kits

The Analog Devices, Inc., ADA4945-1CP-EBZ evaluation board is used to evaluate the performance of the ADA4945-1 fully differential amplifier. The board can be used as either a standalone evaluation board for general purpose differential amplifier evaluation or as an amplifier mezzanine card for specified ADCs. When configured as a mezzanine card the board is easily mounted atop compatible ADC evaluation boards via the 7-pin Headers J1 and J2. This usage enables quick and easy evaluation of multiple amplifier/ ADC combinations.

The evaluation board can be configured to accept either a single-ended or differential input signal.

The board utilizes several two-pin or three-pin headers to control various features of the ADA4945-1. Headers allow the user to easily set the ADA4945-1 high and low output clamp levels, set the output common-mode voltage, choose high or low power mode, and set the digital ground level.

Optimized power and ground planes ensure low noise and high speed operation. Component placement and power supply bypassing are optimized for maximum circuit flexibility and performance. The evaluation board accepts 0402 or 0603 surface mount technology (SMT) components, 0805 bypass capacitors, and 2.54 mm headers.
