MAX40000/MAX40001
1.7V, nanoPower Comparators with Built-In
Reference
General Description
Benefits and Features
The MAX40000/MAX40001 are tiny, single comparators
with built-in voltage references that are ideal for a wide
variety of portable electronics applications, such as cell
phones, portable instruments, and notebooks that have
extremely tight board space and power constraints. The
MAX40000/MAX40001 are available in a 6-bump wafer-
level package (WLP) with 1.11mm x 0.76mm footprint and
a 6-pin SOT23 package. The MAX40000 has a push-pull
output and the MAX40001 has an open-drain output.
● Micropower Operating Current (0.9μA typ, 1.7μA max)
Preserves Battery Power
● Tiny 1.11mm x 0.76mm 6-Bump WLP and SOT23
Packages Save Board Space
● Internal Precision Reference Saves Space and Cost
of an External Reference
• < 1% at Room Temperature, < 2.5% Over Temp
Reference
• Multiple Reference Voltages (1.252V, 1.66V, 1.94V,
and 2.22V)
The devices offer a supply voltage range from 1.7V to
5.5V and consume only 0.9μA of supply current. They also
feature internal filtering to provide high RF immunity, im-
portant in many portable applications.
● Input Voltage Range = -0.2V to 5.7V
● Supply Voltage Range (1.7V to 5.5V) Allows
Operation from 1.8V, 2.5V, 3V, and 5V Supplies
● <10μs Propagation Delay
● Push-Pull (MAX40000) or Open-Drain (MAX40001)
Outputs
The devices have a high-precision integrated reference
that is factory trimmed to an initial accuracy of 1% and bet-
ter than 2.5% over the entire temperature range. Internal
reference voltage options include 1.252V, 1.66V, 1.94V,
and 2.22V. See Ordering Information for help with order-
ing a MAX40000/MAX40001 with a particular voltage ref-
erence value and package type. The reference output is
stable for capacitive loads up to 100pF.
