Analog Devices Inc./Maxim Integrated MAX9053AEUB-T

Overview

MAX9053AEUB-T from Analog Devices is a dual comparator with integrated 2.500V precision voltage reference in a 10-pin µMAX package, consuming only 55µA supply current at 2.7V, featuring rail-to-rail inputs/outputs, ±3mV internal hysteresis, and 400ns propagation delay - ideal for low-power battery-operated window comparator circuits.

For engineers reviewing the MAX9053AEUB-T datasheet, MAX9053AEUB-T pinout, MAX9053AEUB-T application, or MAX9053AEUB-T equivalent, this page delivers verified electrical parameters, validated dual-comparator + reference functionality, A-grade (±0.4% initial accuracy, 6ppm/°C tempco) reference performance, and real-world use cases in precision level detection and IR receiver front-ends.

Technical Context

The MAX9053AEUB-T integrates two independent comparators sharing a single high-accuracy 2.500V reference, with each comparator offering rail-to-rail input common-mode range extending 250mV beyond VEE and VCC, and input bias current as low as 1.0pA. Its internal ±3mV hysteresis eliminates oscillation on slow-moving signals without external components.

The output stage uses a push-pull design capable of sourcing/sinking up to 8mA while limiting supply-current surges during switching - reducing power-supply glitches and minimizing need for large bypass capacitors. The reference employs laser-trimmed thin-film resistors and curvature correction for stable 2.500V output across temperature and load.

FAQ

What is the reference voltage tolerance and temperature coefficient of the MAX9053AEUB-T?

The MAX9053AEUB-T features an A-grade 2.500V reference with ±0.4% initial accuracy over temperature and a typical temperature coefficient of 6ppm/°C. This specification is guaranteed across the −40°C to +85°C operating range and enables stable trip-point generation in precision analog monitoring circuits without recalibration.

Does the MAX9053AEUB-T support rail-to-rail input operation, and what is its common-mode voltage range?

Yes, the MAX9053AEUB-T supports true rail-to-rail input operation with a common-mode voltage range from VEE − 0.25V to VCC + 0.25V. This allows the device to accurately compare signals that extend slightly beyond the supply rails - such as sensor outputs near ground or VCC - without clipping or error, making it suitable for wide-dynamic-range industrial sensing.

Can the MAX9053AEUB-T drive capacitive loads on its REF pin, and what is the maximum stable value?

Yes, the MAX9053AEUB-T reference output is stable with capacitive loads up to 4.7nF, as confirmed in the datasheet's Electrical Characteristics table. This eliminates the need for external compensation and allows direct connection to ADC reference inputs or filtering capacitors without risk of oscillation - simplifying design in data-acquisition systems.

What is the propagation delay of the MAX9053AEUB-T, and how does it vary with overdrive?

The MAX9053AEUB-T has a typical propagation delay of 400ns with 100mV input overdrive and 450ns with 50mV overdrive (CL = 15pF, VCC = 2.7V). This fast, predictable delay enables reliable timing in IR demodulation and high-speed window detection, while the low sensitivity to overdrive ensures consistent performance across varying signal amplitudes.

How does the MAX9053AEUB-T minimize supply-current surges during output switching?

The MAX9053AEUB-T uses a proprietary output-stage design that limits supply-current transients during switching - reducing typical current spikes by >90% versus conventional comparators. This virtually eliminates supply-line glitches, lowers required bypass capacitance, and extends battery life in portable equipment where power integrity is critical.
