ELECTRICAL CHARACTERISTICS
(V
(Note 1)
Note 1: All devices are 100% production tested at T
Note 2: Typical value only, set-point input voltage range determined by logarithmic slope and logarithmic intercept.
Note 3: Set-point slew rate is the rate at which the reference level voltage, applied to the inverting input of the g
Note 4: Typical min/max range for detector.
Note 5: MAX4000 internally AC-coupled.
Note 6: MAX4001/MAX4002 are internally resistive-coupled to V
