NOTES: 1. All typical limits are at TA = 25°C unless otherwise specified. Junction temperature = ambient temperature for low temperature limits.
Junction temperature = ambient temperature + 7°C at high temperature limit over temperature tested specifications.
2. Current is considered positive out of node. VCM is the input common-mode voltage.
3. Tested < 3dB below minimum specified CMR at ±CMIR limits.
