Precision multifunction input & output DAQ

Block diagram

Overview

Our integrated circuits and reference designs offer a wide range of system implementations that cover different electrical inputs, outputs, speed and accuracy while maximizing system resolution and bandwidth and minimizing noise and power consumption as you design your data acquisition (DAQ) instruments.

Design requirements

  • System optimization to achieve best in class signal-to-noise ratio (SNR), bandwidth and dynamic range.
  • High precision, low drift signal chain architectures to minimize measurement errors.
  • Low jitter, high speed reinforced isolation to minimize the SNR degradation.
  • Low noise and low external machine interface (EMI) power supply to minimize the measurement errors.
