Note 1: Guaranteed by design.
Note 2: Maximum output current (sinking/sourcing) in which the gain changes by less than 0.1%.
Note 3: This specification represents the typical temperature coefficient of an on-chip thin film resistor. In practice, the temperature
coefficient of the gain for the MAX4194 will be dominated by the temperature coefficient of the external gain-setting resistor.
