Note 1: All devices are 100% production tested at T_A = +25°C and are guaranteed by design for T_A = -40°C to +85°C as specified.
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_m stage, responds to
a voltage step at the SET pin (see Figure 1).
Note 4: Typical min/max range for detector.
Note 5: Pin capacitance to ground.
