Product Details

MAX40070/MAX40072 is a family of single micropower comparators ideal for a wide variety of battery operated devices in computing, industrial, medical, and IoT applications that have extremely tight board space and power constraints while requiring high levels of precision. These comparators are offered with an open-drain output in a small 8-bump (0.35µm pitch) wafer level package as well as a TDFN package.

The MAX40070/MAX40072 family features a rail-to-rail input voltage range of 0V to +27.5V on IP pin, independent of the supply voltage. It also features internal filtering to provide high EMI immunity.

The MAX40070/MAX40072 uses a high-precision integrated reference voltage (1.6V) as well as a precision internal current source that allows customized comparator threshold and hysteresis by using two external resistors.

These comparators consume only 16µA (typ) supply current with a propagation delay of 2µs. They all operate over the extended -40°C to +125°C temperature range.

View Detailed Evaluation Kit Information

The MAX40070 evaluation kit (EV kit) is fully assembled and tested PC board that evaluates the MAX40070 single comparator with internal voltage reference. The MAX40070 EV kit has an open-drain output. The EV kit comes with a MAX40070ANA16+ installed that operates of a VDD supply between 3.1V and 36V, an internal reference voltage of 1.6V, and has a wide 0V to +24.2V input voltage (IP) range. The EV kit demonstrates the MAX40070ANA16+ in a tiny, 1.008mm x 1.428mm, 8-bump wafer-level package (WLP) with 0.35mm bump spacing. The EV kit can be used to evaluate the entire family of MAX40070 with 8-bump WLP option.
