Product details
Overview
MAX9053BEUB-T from Analog Devices is a dual micropower comparator with integrated 2.500V precision voltage reference, designed for single-supply operation from 2.7V to 5.5V. It features rail-to-rail inputs/outputs, 55μA supply current, ±3mV internal hysteresis, and 400ns propagation delay-enabling high-accuracy window detection in battery-powered sensor monitoring systems.
For engineers reviewing the MAX9053BEUB-T datasheet, MAX9053BEUB-T pinout, MAX9053BEUB-T application, or MAX9053BEUB-T equivalent, this page delivers verified electrical specs, package mapping to 10-pin μMAX, functional role in precision thresholding, and validated alternative options for low-power comparator + reference integration.
Technical Context
The MAX9053BEUB-T integrates two independent comparators sharing one laser-trimmed series-mode voltage reference. Its input stage supports common-mode voltages from VEE −0.25V to VCC +0.25V, with typical 1.0pA input bias current and ±0.5mV offset voltage (A grade) or ±1.0mV (B grade).
The output stage uses a push-pull rail-to-rail design capable of sinking and sourcing up to 8mA, while its proprietary switching architecture limits supply-current surges-reducing power-supply glitches and eliminating need for large bypass capacitors in space-constrained designs.
Key Specifications

| Stable for 0–4.7nF REF load capacitance | Enables use of local filtering without oscillation risk - simplifies EMI mitigation in noisy industrial environments. |
Applications
| Window Comparators | Precision Battery Management |
|---|---|
Use Scenario: Monitoring lithium battery voltage between 3.0V (low) and 4.2V (high) thresholds to trigger charge/discharge control. IC Role / Device Role / Timing Role: Dual comparator compares battery voltage against upper/lower thresholds derived from internal 2.500V reference via resistor dividers. Use Value: Eliminates external reference IC and two discrete comparators, reducing BOM count and layout complexity while maintaining ±0.4% threshold accuracy. | Use Scenario: Detecting overvoltage, undervoltage, and overtemperature conditions in sealed lead-acid backup systems. IC Role / Device Role / Timing Role: One comparator monitors scaled battery voltage; the other monitors thermistor-derived voltage - both referenced to same 2.500V source. Use Value: Common reference ensures matched drift behavior across thresholds, improving long-term reliability in wide-temperature deployments. |
| IR Receivers | Digital Line Receivers |
Use Scenario: Demodulating 38kHz infrared carrier signals in remote-control receivers with ambient-light rejection. IC Role / Device Role / Timing Role: Fast 400ns propagation delay enables clean zero-crossing detection on modulated IR pulses; rail-to-rail outputs drive CMOS logic directly. Use Value: Low 55μA quiescent current extends battery life in remote controls; internal hysteresis rejects noise without external components. | Use Scenario: Converting RS-232 or CAN bus differential signals to single-ended logic levels in isolated communication interfaces. IC Role / Device Role / Timing Role: Comparator A detects positive edge; Comparator B detects negative edge - enabling full-duplex signal recovery from noisy transmission lines. Use Value: Input common-mode range extending 250mV beyond rails accommodates residual common-mode noise on long cables without clipping. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator + precision reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9052BEUA | Same dual comparator + 2.500V reference, but in 8-pin μMAX (smaller footprint, no N.C. pin) | Lower pin count reduces routing complexity; lacks dedicated INB+ pin - requires shared input configuration | Select when board space is constrained and dual independent noninverting inputs are not required |
| TLV3702IDR | Low-power dual comparator only (no integrated reference); requires external 2.5V reference (e.g., REF3025) | Higher BOM count and layout area; reference drift and matching must be managed separately | Select when higher speed (>1µs propagation) or rail-to-rail input beyond supplies is unnecessary |
Compared with MAX9053BEUB-T, MAX9052BEUA offers identical functionality in a smaller 8-pin package but sacrifices pin independence for INB+, while TLV3702IDR demands external reference design effort and introduces additional drift sources-making MAX9053BEUB-T optimal for compact, high-accuracy dual-threshold systems.

FAQ
What is the operating temperature range for MAX9053BEUB-T?
The MAX9053BEUB-T is rated for operation from −40°C to +85°C. This extended industrial temperature range ensures reliable performance in harsh environments such as factory automation equipment, outdoor sensor nodes, and automotive body-control modules where thermal cycling is common. The device's reference stability and comparator offset specifications are guaranteed across this full range.
Does MAX9053BEUB-T require an external reference capacitor on the REF pin?
No, the MAX9053BEUB-T does not require an external capacitor on the REF pin for stability. It is internally compensated and remains stable with capacitive loads from 0 to 4.7nF. However, adding a 100nF ceramic capacitor is recommended in applications subject to rapid load or supply transients - it improves transient response and reduces overshoot/undershoot during step changes in reference current demand.
How is the internal hysteresis implemented in MAX9053BEUB-T?
The MAX9053BEUB-T incorporates fixed internal hysteresis of ±3mV, achieved through on-chip positive feedback circuitry. This hysteresis is centered around the comparator's input offset voltage and ensures clean, bounce-free output transitions even with slow-moving or noisy input signals - eliminating the need for external hysteresis resistors in most threshold-detection applications.
Can MAX9053BEUB-T drive logic-level inputs directly?
Yes, MAX9053BEUB-T can drive CMOS and TTL logic inputs directly. Its rail-to-rail push-pull outputs deliver VOH ≥ 4.45V and VOL ≤ 0.55V at VCC = 5V with 8mA load, meeting standard 5V logic high/low thresholds. At 3.3V supply, VOH ≥ 2.3V and VOL ≤ 0.4V ensure compatibility with 3.3V logic families - no level-shifter IC is needed.
What is the maximum capacitive load the REF output can drive?
The REF output of MAX9053BEUB-T is stable with capacitive loads up to 4.7nF, as confirmed by Analog Devices' characterization data. This specification covers ceramic, tantalum, and electrolytic capacitors. Loads exceeding 4.7nF may cause instability or excessive settling time; for larger bulk capacitance, place it after a series resistor (e.g., 10Ω) to isolate the reference output from the capacitor's reactive impedance.
