Offset Drift Measurement Principles for load cell digital measurment using Acam TDC technology for Time to Digital, High Resolution, Applications

Offset drift of the complete electronics 1 in temperature range -20 °C ... + 90 °C Vio = Vcc = 3 V, 1 KOhm SG with 0 mV/V strain	Offset drift half-bridges: 55 nV/K ; Offset drift full-bridge: < 2 nV/K
Gain+Offset drift of the complete electronics 1 in ppm of maximum strain in temperature range -20 °C ... + 90 °C Vio = Vcc = 3 V, 1 KOhm SG with 2.5 mV/V strain	Gain+offset drift half-bridge1: 1.02 ppm ; Gain+offset drift half-bridge2: 1.16 ppm ; Offset drift full-bridge: < 2 nV/K

1 : measured with PSA2 evaluation board, SG at constant temperature
