Overview
The MAX40005ANS02+T is a single-channel analog comparator from the nanoPower family, manufactured by Analog Devices Inc./Maxim Integrated. It features an inverting input and push-pull output configuration housed in a 4-bump WLP package measuring 0.73mm x 0.73mm. The device operates on a supply voltage range of 1.7V to 5.5V with a typical supply current of 500nA. It includes a factory-trimmed internal reference voltage preset at 0.2V. Electrical specifications include a propagation delay of 9µs (typical), 8mV hysteresis, and operation across a temperature range of -40°C to +125°C.
Feature Summary
- Ultra-low power consumption preserves battery life in portable applications
- Tiny 4-bump wafer-level package saves significant board space
- Internal filtering provides high RF immunity against noise
- High impedance inputs maintain functionality even when powered down
Applications
- Mobile devices
- Portable medical devices
- Notebook computers
- Electronic toys
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free packaging details prior to integration. Ensure proper handling procedures for the ultra-tiny WLP package are followed during assembly to prevent mechanical damage.
Selection Notes
Select this part for designs requiring minimal footprint and low quiescent current. The inverting input polarity dictates that the output asserts low when the input exceeds the internal reference. Verify that the push-pull output capability meets the interface requirements without needing external pull-up resistors.
Part Context
This component belongs to the MAX40002–MAX40005 series of nanoPower comparators. These devices are engineered for extreme size and power constraints, offering both WLP and SOT23 packaging options. The series supports various input polarities and output types to accommodate diverse system architectures.
Replacement Considerations
Compatible substitutes within the same family include MAX40002ANS02+T, MAX40003ANS02+T, and MAX40004ANS02+T. Verify pin compatibility and electrical characteristics before substitution.
