All devices are 100% production tested at TA = +25°C. Specifications over temperature are guaranteed by design.
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.
VOS is defined as the center of the input-referred hysteresis zone. See Figure 1.
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 IB reverses direction as VCM approaches either supply rail.
Specified over the full common-mode voltage range (VCMR).
Specification is for current flowing into or out of the output pin for VOUT driven to any voltage from VCC to GND while the part is
in shutdown.
Specified between any two channels in the MAX9142/MAX9144.
Specified as the difference between tPD+ and tPD- for any one comparator.
Applies to the MAX9141 only for both SHDN and LE.
Applies to the MAX9141 only. Comparator is active with LE driven high and is latched with LE driven low (VOD = 10mV). See
Figure 2.
Applicable to the MAX9141 only. Comparator is active with the SHDN driven high and is shutdown with SHDN driven low.
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.
