Low signal delay: 0.8 µs.
Typical input offset: ±0.40 µV.
Typical gain error: ±0.06%.
Excellent drift specifications - 0.5 µV/°C offset drift -.
9 ppm/°C typical gain drift.
Typical nonlinearity: 0.003% full-scale.
Typical SNR: 82 dB over 100 kHz bandwidth.
Typical THD:.
88 dB.
High common-mode transient immunity: 75 kV/µs.
Autom.
