Note 1: Inferred from the 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.
Note 2: 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.
Note 3: VOS is defined as the center of the input-referred hysteresis zone. See Figure 1.
Note 4: The polarity of IB reverses direction as VCM approaches either supply rail. See Typical Operating Characteristics for more
detail.
Note 5: Specified over the full common-mode range (VCMR).
Note 6: Applies to the MAX941 only when in shutdown mode. Specification is for current flowing into or out of the output pin for
VOUT driven to any voltage from V+ to GND.
Note 7: Typical power dissipation specified with V+ = 3V; maximum with V+ = 6V.
Note 8: Parameter is guaranteed by design and specified with VOD = 5mV and CLOAD = 15pF in parallel with 400µA of sink or
source current. VOS is added to the overdrive voltage for low values of overdrive. See Figure 2.
Note 9: Specified between any two channels in the MAX942/MAX944.

Note 14: The MAX941EUA and MAX942EUA are 100% production tested at TA = +25°C. Specifications over temperature are
guaranteed by design.
