MAX40070ANA16+T

Overview

The MAX40070ANA16+T is a single micropower comparator from Analog Devices. It features a supply voltage range of 2.2V to 36V and consumes 16µA typical supply current. The device provides a rail-to-rail input common-mode range of 0V to 27.5V on the IP pin, independent of VDD. It includes an internal 1.6V reference with 1.3% accuracy and a 3µA internal current source for threshold customization. Propagation delay is typically 2µs. The output is open-drain, capable of sinking 2mA. It operates over -40°C to +125°C in an 8-bump WLP package.

Feature Summary

• Rail-to-rail input voltage range extending up to 27.5V independent of supply voltage
• Internal high-precision voltage reference and current source for customized thresholds
• Open-drain output stage allowing parallel connection and pull-up beyond VDD
• Integrated internal hysteresis to ensure clean switching

Applications

• Notebook and tablet computers
• Portable medical devices
• Industrial equipment
• IoT applications

Procurement Notes

Verify the specific suffix ANA16 corresponds to the 8-bump WLP package configuration. Confirm RoHS compliance status indicated by the plus sign. Ensure the EN pin logic level matches the system design, as it is active low. Check availability for future product variants within the family if TDFN options are required later.

Selection Notes

Select this component when board space is constrained due to its tiny WLP footprint. It is suitable for battery-operated systems requiring low quiescent current. Use external resistors if the default 1.6V threshold or 90mV internal hysteresis does not meet application requirements. Ensure the pull-up resistor value supports the required speed and load conditions.

Part Context

This part belongs to the MAX40070/MAX40072 family of high-voltage, low-power comparators. The MAX40070 variant specifically utilizes the WLP package, while the MAX40072 uses a TDFN package. Both share identical electrical characteristics and functionality, differing only in physical packaging.

Replacement Considerations

MAX40072ATA16+T offers identical electrical performance in a TDFN package.
