Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

DC ELECTRICAL CHARACTERISTICS—Dual Supplies

(VCC = +5V; VEE = -5V; IN+ = 0; DISABLE_ ≥ 3.2V; MAX4188: AV = +2V/V, RF = RG = 910Ω for RL = 1kΩ and RF = RG = 560Ω for RL

= 150Ω; MAX4189: AV = +1V/V, RF = 1600Ω for RL = 1kΩ and RF = 1100Ω for RL = 150Ω; MAX4190: AV = +2V/V, RF = RG = 1300Ω

for RL = 1kΩ, RF = RG = 680Ω for RL = 150Ω; TA = TMIN to TMAX, unless otherwise noted. Typical values are specified at

TA = +25°C.)
