MAX40000/MAX40001
EVALUATION KIT AVAILABLE
1.7V, 0.9µA Comparators with
Built-in Reference
General Description
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.
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,
important in many portable applications.
The devices have a high-precision integrated reference
that is factory trimmed to an initial accuracy of 1% and
better 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
ordering a MAX40000/MAX40001 with a particular voltage
reference value and package type. The reference output
is stable for capacitive loads up to 100pF.
These devices are fully specified over -40°C to +125°C
automotive temperature range.
