Specifications

All specifications are guaranteed unless noted otherwise. All specifications apply to all models unless noted otherwise.

Gain settings

100x, 10x, 1x, 0.1x

CMRR

≥100,000: 1 DC - 10 kHz

Signal ranges

Gain setting	Common Mode signal range	Differential signal range 1	Max offset
100x	±10 V	0.1 V	±1.0 V
