ELECTRICAL CHARACTERISTICS (continued)

(VCC = +5V, VEE = 0V, RL = 25kΩ tied to VCC/2, VREF = VCC/2, TA = TMIN to TMAX, unless otherwise noted. Typical values are at

TA = +25°C.)

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.
