Overview
The MAX40004ANS05+ is a single-channel analog comparator from the nanoPower family, manufactured by Analog Devices Inc./Maxim Integrated. It features a push-pull output and an inverting input configuration with a factory-trimmed internal reference voltage of 0.5V. The device operates within a supply voltage range of 1.7V to 5.5V and consumes a typical supply current of 500nA. It is housed in a 4-bump WLP package with dimensions of 0.73mm x 0.73mm. Electrical specifications include a propagation delay of 9µs (typical) at 100mV overdrive, an input offset voltage of 27mV maximum, and an operating temperature range of -40°C to +125°C.
Feature Summary
- Ultra-low power consumption of 500nA for extended battery life
- Tiny 0.73mm x 0.73mm footprint ideal for space-constrained designs
- Integrated 0.5V reference eliminates external components
- Push-pull output stage removes need for pull-up resistors
Applications
- Mobile devices
- Portable medical devices
- Notebook computers
- Electronic toys
Procurement Notes
Verify the specific suffix '05' confirms the 0.5V internal reference setting. Confirm the 'ANS' designation corresponds to the 4-bump WLP package variant. Ensure compatibility with the required inverting input logic level. Check for RoHS compliance status indicated by the '+' suffix.
Selection Notes
Select this part when board space is limited and low quiescent current is critical. The push-pull output simplifies interface design compared to open-drain variants. Verify that the 0.5V threshold aligns with the signal levels being monitored. Consider the 9µs propagation delay against system timing requirements.
Part Context
This component belongs to the MAX40002–MAX40005 series of nanoPower comparators. These devices share common electrical characteristics but differ in input polarity, output type, and internal reference voltage options. The MAX40004 specifically offers a noninverting input with push-pull output, while the MAX40005 provides an inverting input with push-pull output.
Replacement Considerations
Direct substitutes within the same family include MAX40004ANS02+, MAX40004ANS09+, and MAX40004ANS12+T, which offer different internal reference voltages. For open-drain alternatives, consider the MAX40002 or MAX40003 series.
