MAX40001ANT22+

The MAX40000/MAX40001ANT22+T 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/MAX40001ANT22+T 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 MAX40001ANT22+T 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/MAX40001ANT22+T 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.
