220ns, 12μA, 6-Bump WLP
Comparators with Shutdown
MAX40008/MAX40009
General Description
Benefits and Features
● 220ns Propagation Delay
The MAX40008/MAX40009 are single micro-power
comparators featuring low-voltage operation and
rail-to-rail inputs. Their operating supply voltage range
from 1.7V to 5.5V, which makes them ideal for systems
running from nominal 1.8V to 5V supplies.
● Tiny 0.73mm x 1.1mm with 0.35mm Pitch 6-Bump
WLP and SOT23 Packages Save Board Space
● Rail-to-Rail Inputs
● Low Operating Current ≤ 17μA (max) Over
While only consuming 12μA of supply current, the
MAX40008/MAX40009 achieve a 220ns propagation delay.
These devices feature 0.5mV (typ) input offset voltage and
internal hysteresis, ensuring clean output switching, even
with slow-moving input signals.
Temperature
● No Phase Reversal for Overdriven Inputs
● Integrated RF Immunity Filters
● Supply Voltage Range (1.7V to 5.5V) Allows
The output stage’s unique design limits supply-current
surges while switching, virtually eliminating the supply
