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.
All production AC testing is done at 100MHz.
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:
MAX4000 internally AC-coupled.
Note 6:
MAX4001/MAX4002 are internally resistive-coupled to V
CC
.
