TIDA-00765 Reference Design

Texas Instruments

1g Resolution over 15kg Range Sub-100nVpp Noise Front-End Reference Design


TIDA-00765 is a less than 100nVpp analog front end for resistive strain gauge bridge load cell-based weight and vibration measurement. It is ideally suited for appliances: which require high-resolution due to large dynamic range or have considerable weight offset. In the face of significant levels of switching supply noise and rapid temperature changes: drift and interference are common issues in harsh environments. The design’s high integration: AC excitation: and robust filtering suppress drift and interference to ensure consistent performance in tough environments.

  • Captures outputs of both multiple and single resistive strain gauge-based load cell bridges simultaneouslyConsistent AC excitation robustly eliminates drift introduced by parasitic thermocouples and other causesHighly robust to >500mVpp 100-kHz switching-supply noiseCaptures vibrations up to 500 Hz with sample rate ≤2 kSps
