V OUT tested limit at V SENSE = 0mV, 0 ≤ VCM1 ≤ VS. NOTE: (1) INA193, INA196 V OUT Tested Limit = 0.4V. INA194, INA197 V OUT Tested Limit = 1V.

Example for Low VSENSE Cases 1 and 3 (INA195A, INA198A: Gain = 100) This region of operation is the least accurate for the INA193A–INA198A family. To achieve the wide input common-mode voltage range, these devices use two op amp front ends in parallel. One op amp front end operates in the positive input common-mode voltage range, and the other in the negative input region. For this case, neither of these two internal amplifiers dominates and overall loop gain is very low. Within this region, VOUT approaches voltages close to linear operation levels for Normal Case 2. This deviation from linear operation becomes greatest the closer VSENSE approaches 0 V. Within this region, as VSENSE approaches 20 mV, device operation is closer to that described by Normal Case 2. Figure 3 illustrates this behavior for the INA195A. The VOUT maximum peak for this case is tested by maintaining a constant VS, setting VSENSE = 0 mV and sweeping VCM from 0 V to VS. The exact VCM at which VOUT peaks during this test varies from part to part, but the VOUT maximum peak is tested to be less than the specified VOUT tested limit. Figure 3.
