Overview
The MAX9052AESA is a micropower, single-supply analog comparator integrated with a precision voltage reference. It features dual comparators and one reference within an 8-pin SO package. The device operates from a supply voltage range of 2.7V to 5.5V. It consumes only 60µA of supply current at 5V. The propagation delay is 400ns. Input offset voltage is typically 0.5mV. The internal reference provides a fixed output of 2.500V. Common-mode input voltage extends 250mV beyond the supply rails. Output stages are rail-to-rail push-pull.
Feature Summary
- Integrates dual comparators with a precision voltage reference in a compact package
- Features rail-to-rail inputs and outputs for wide signal compatibility
- Includes internal hysteresis to ensure clean switching on slow-moving signals
- Utilizes unique output stage design to minimize supply current surges during transitions
Applications
- Precision battery management systems
- Window comparator circuits
- IR receivers
- Level translators
- Digital line receivers
Procurement Notes
Verify the specific suffix 'A' indicates the A grade with 0.4% initial accuracy and 6ppm/°C temperature coefficient. Confirm the 'E' denotes the 8-pin SO package type. Ensure the '+' suffix confirms lead-free and RoHS compliance status. Check the operating temperature range specification for -40°C to +85°C coverage. Validate that the datasheet revision matches the required electrical characteristics.
Selection Notes
Select this component when dual independent comparisons are required alongside a stable 2.5V reference source. The low quiescent current makes it suitable for battery-powered applications where power conservation is critical. The extended common-mode input range allows operation even if input signals slightly exceed the supply rails. Consider the 400ns propagation delay for timing-sensitive digital interface designs.
Part Context
This part belongs to the MAX9038–MAX9043/MAX9050–MAX9053 family of micropower comparators. These devices combine low-power comparators with precision voltage references. The MAX9052 specifically offers dual comparators sharing a single reference. Other variants in the series provide single comparators or different reference voltages such as 1.23V or 2.048V.
Replacement Considerations
The MAX9053AESA serves as a direct functional substitute within the same package, differing only by having uncommitted inverting inputs instead of a shared reference connection.
