Overview
The MAX40005ANS02+ is a single-channel analog comparator in a 4-bump WLP package. It operates on a supply voltage range of 1.7V to 5.5V with a typical supply current of 500nA. The device features an inverting input and a push-pull output. An internal reference voltage is factory-trimmed to 0.2V (typical). Electrical characteristics include a propagation delay of 9µs (typical) at 100mV overdrive, an input offset voltage of 0.5mV (typical), and an operating temperature range from -40°C to +125°C.
Feature Summary
- Ultra-low power consumption preserves battery life in portable applications
- Tiny 0.73mm x 0.73mm footprint saves board space
- Internal filtering provides high RF immunity
- Input voltage range extends beyond the supply rail
Applications
- Mobile devices
- Portable medical devices
- Notebook computers
Procurement Notes
Verify the specific suffix '02' confirms the 0.2V internal reference voltage. Confirm the 'ANS' designation matches the required 4-bump WLP package. Check for lead-free/RoHS compliance status indicated by the '+' suffix. Ensure the component meets the required automotive temperature specifications if applicable.
Selection Notes
Select this part when a compact form factor and low quiescent current are critical. The inverting configuration requires the signal to be compared against the internal threshold appropriately. Verify that the push-pull output capability aligns with the downstream logic requirements without needing external pull-up resistors.
Part Context
This component belongs to the MAX40002–MAX40005 nanoPower comparator family. These comparators are designed for extreme size and power constraints. The MAX40005 variant specifically offers an inverting input polarity combined with a push-pull output stage, distinguishing it from open-drain variants within the same series.
Replacement Considerations
Other members of the MAX4000x series may serve as alternatives if different reference voltages or input polarities are acceptable. Verify pin compatibility between WLP packages before substitution.
