All devices are 100% production tested at T
Inferred from PSRR test.
Inferred from CMRR test. Note also that either or both inputs can be driven to the absolute maximum limit (0.3V beyond either
supply rail) without damage or false output inversion.
V
The input-referred trip points are the extremities of the differential input voltage required to make the comparator output
change state. The difference between the upper and lower trip points is equal to the width of the input-referred hysteresis
zone. See Figure 1.
The polarity of I
Specified over the full common-mode voltage range (V
Specification is for current flowing into or out of the output pin for V
in shutdown.
Specified between any two channels in the MAX9142/MAX9144.
Figure 2.
Shutdown enable time is the delay when the SHDN is driven high to the time the output is valid. Shutdown disable time is the
delay when the SHDN is driven low to the time the comparator shuts down.
