Overview
The MAX9052AEUA-T is a micropower, single-supply integrated circuit featuring dual comparators and a precision voltage reference. It operates from a 2.7V to 5.5V supply with quiescent current of 55µA at 2.7V and 60µA at 5V. The device includes a 2.500V reference with ±0.4% initial accuracy (A grade) and 6ppm/°C temperature coefficient. Comparators offer rail-to-rail inputs extending 250mV beyond rails, internal ±3mV hysteresis, and 400ns propagation delay. Outputs are push-pull, sinking and sourcing up to 8mA. It is housed in an 8-pin µMAX package.
Feature Summary
- Integrates dual low-power comparators with a precision voltage reference in a compact footprint.
- Features rail-to-rail input and output stages with extended common-mode range exceeding supply rails.
- Includes internal hysteresis to ensure clean switching for slow-moving signals.
- Output stage design minimizes supply current surges during transitions to prevent power glitches.
Applications
- Precision battery management systems
- Window comparator circuits
- IR receivers
- Level translators
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the 'A' grade designation corresponds to the required 0.4% initial accuracy and 6ppm/°C temperature coefficient specifications. Ensure the 8-pin µMAX package form factor matches the target PCB layout constraints.
Selection Notes
Select this component for applications requiring dual signal comparison alongside a stable voltage reference within tight space constraints. It is suitable for battery-operated systems due to its low quiescent current consumption. Consider the rail-to-rail input capability if input signals may exceed the supply voltage limits slightly.
Part Context
This part belongs to the MAX9038–MAX9053 family of micropower comparator and reference ICs. It shares architectural similarities with the MAX9042 but utilizes a 2.500V reference instead of 2.048V. The family supports various packages including UCSP, SOT23, SO, and µMAX, catering to different size and pin-count requirements.
Replacement Considerations
The MAX9052BEUA is available as a B-grade alternative with 1% initial accuracy and 100ppm/°C tempco. Other family members like MAX9042 share similar functionality but differ in reference voltage.
FAQ
What is the maximum capacitive load the reference output can drive?
The reference output is stable for capacitive loads up to 4.7nF without requiring an external output capacitor for frequency stability.
How does the output stage handle switching transients?
The unique output stage design limits supply current surges while switching, virtually eliminating the supply glitches typical of many other comparators.
