Overview

Whether you are designing a precision balance, bench scale, continuous weighing scale or any other weigh device, our integrated circuits and reference designs help you create a high-performing solution.

Design requirements

    Modern weigh scale designs often require:

  • High-precision measurement with short measuring times.
  • Highly-integrated power systems with low noise, low external machine interface (EMI) and high efficiency.
  • Support for existing and upcoming wireless and wired interfaces.
  • Low drift over a wide range of temperature and electrical conditions.
