Overview
The MAX40009ANT+T is a single-channel analog comparator from Analog Devices, packaged in a 6-bump WLP. It operates on a supply voltage of 1.7V to 5.5V with a typical quiescent current of 12μA and a maximum of 17μA. The device features rail-to-rail inputs, a push-pull output stage, and an internal hysteresis of 3mV. Propagation delay is typically 220ns at 100mV overdrive. It includes a shutdown input that reduces current to 1μA. Operating temperature range is -40°C to +125°C.
Feature Summary
- Push-pull output stage provides robust drive capability without external pull-up resistors.
- Integrated internal hysteresis ensures clean switching for slow-moving signals.
- Low-power shutdown mode significantly reduces quiescent current consumption.
- Rail-to-rail input common-mode range accommodates full signal swing.
Applications
- Mobile communications systems
- Portable and battery-powered devices
- Window comparator circuits
- Threshold detectors and discriminators
Procurement Notes
Verify the specific suffix 'ANT' corresponds to the 6-bump WLP package and automotive temperature grade (-40°C to +125°C). Confirm RoHS compliance status via the '+' designation. Ensure the application requires the push-pull output characteristic distinct from the open-drain MAX40008 variant. Cross-reference the datasheet revision date against manufacturing lot codes for production validity.
Selection Notes
Select this component when board space is constrained by the tiny WLP footprint. Choose over the MAX40008 if a push-pull output is required instead of an open-drain configuration. Consider the low propagation delay for timing-critical applications. Verify that the 12μA operating current meets system power budgets compared to higher-speed alternatives.
Part Context
This part belongs to the MAX40008/MAX40009 family of micro-power comparators designed for low-voltage operation. It shares core electrical characteristics with the MAX40008 but differs in its output stage topology. The series targets portable electronics requiring high efficiency and minimal component count within compact form factors.
Replacement Considerations
MAX40008ANT+T serves as a functional substitute if the circuit utilizes an external pull-up resistor compatible with the open-drain output. Verify pinout compatibility between the WLP packages before substitution.
FAQ
Does the MAX40009 require an external pull-up resistor?
No, the MAX40009 features a push-pull output stage that does not require an external pull-up resistor, unlike the open-drain MAX40008.
What is the purpose of the SHDN pin?
The SHDN pin is an active-low shutdown input that reduces the supply current to approximately 1μA when driven low, conserving power in standby modes.
