Feedback Amplifiers with High-Speed Disable

DC ELECTRICAL CHARACTERISTICS—Single Supply

(VCC = +5V; VEE = 0; IN+ = 2.5V; DISABLE_ ≥ 3.2V; RL to VCC / 2; MAX4188: AV = +2V/V, RF = RG = 1.1kΩ for RL = 1kΩ and RF = RG

= 620Ω for RL = 150Ω; MAX4189: AV = +1V/V, RF = 1500Ω for RL = 1kΩ and RF = 1600Ω 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.)
