Product details
Overview
The MAX9053BEUB from Analog Devices is a dual micropower comparator with integrated 2.500V precision voltage reference, operating from 2.7V to 5.5V supply, consuming only 55µA typical supply current, featuring rail-to-rail inputs/outputs, ±3mV internal hysteresis, and 400ns propagation delay - ideal for battery-powered precision level detection in portable instrumentation.
For engineers reviewing the MAX9053BEUB datasheet, MAX9053BEUB pinout, MAX9053BEUB application, or MAX9053BEUB equivalent, this page delivers verified functional role, validated A-grade reference accuracy (±0.4%), confirmed µMAX-10 package mapping, and real-world design values for supply current, input offset, output drive, and capacitive-load stability - all critical for low-power sensor interface and window comparator designs.
Technical Context
The MAX9053BEUB integrates two independent comparators sharing one high-stability 2.500V reference, with each comparator offering rail-to-rail input range extending 250mV beyond VEE and VCC, 1.0pA typical input bias current, and ±7.0mV max input offset over –40°C to +85°C. Its push-pull output stage sinks/sources up to 8mA while limiting switching current surges to minimize supply glitches.
The internal 2.500V reference achieves ±0.4% initial accuracy (A grade), 6ppm/°C typical tempco, 4.7nF capacitive-load stability, and <105µVRMS noise (10Hz–10kHz), enabling direct use in ADC reference, threshold calibration, and precision battery monitoring without external buffering.

Applications
| Battery Voltage Monitoring | Window Comparator for Sensor Thresholds |
|---|---|
Use Scenario: Real-time monitoring of Li-ion battery pack voltage across charge/discharge cycles in portable medical devices. IC Role / Device Role / Timing Role: Dual comparator compares battery voltage against upper (4.2V) and lower (3.0V) thresholds derived from 2.500V reference via resistor dividers; REF supplies stable reference for both. Use Value: Enables precise end-of-charge and low-voltage shutdown with <10mV total error budget, extending battery life and preventing over-discharge damage. | Use Scenario: Detecting out-of-range temperature readings from a PT100 RTD in HVAC control systems using a 4–20mA loop. IC Role / Device Role / Timing Role: One comparator monitors high-limit (e.g., 35°C), the other low-limit (e.g., 5°C); REF sets accurate trip points independent of supply variation. Use Value: Achieves ±0.5°C threshold accuracy over –40°C to +85°C ambient, eliminating false alarms caused by reference drift in discrete solutions. |
| Digital Line Receiver with Level Translation | IR Signal Demodulation |
Use Scenario: Converting legacy 5V TTL logic signals to 3.3V microcontroller inputs in industrial PLC backplanes. IC Role / Device Role / Timing Role: Comparator A acts as level translator using REF as 2.5V threshold; OUTA drives 3.3V GPIO with rail-to-rail swing and 8mA drive strength. Use Value: Eliminates need for dedicated level-shifter ICs; 400ns propagation delay supports data rates up to 1Mbps with timing margin. | Use Scenario: Recovering digital data from modulated IR receiver outputs in remote-control receivers. IC Role / Device Role / Timing Role: Comparator B compares IR envelope signal to time-averaged DC level generated by RC network on INA−; REF stabilizes bias point. Use Value: Provides robust noise immunity and consistent zero-crossing detection across varying ambient light conditions, reducing missed commands. |
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 |
|---|---|---|---|
| MAX9053AEUB | A-grade reference (±0.4% initial accuracy, 6ppm/°C tempco) vs. B-grade (±1%, 100ppm/°C) in MAX9053BEUB | Required where reference stability dominates system accuracy (e.g., metrology-grade calibration) | Select MAX9053AEUB when long-term reference drift must be minimized; MAX9053BEUB suffices for cost-sensitive industrial monitoring |
| TLV3702IDR | Single-supply dual comparator only (no integrated reference); requires external 2.5V reference (e.g., REF3025) | Higher BOM count and layout complexity; reference matching and drift add error sources | Choose TLV3702IDR only if existing design already uses REF3025 and space allows separate components |
Compared with MAX9053AEUB, the MAX9053BEUB trades 0.6% reference accuracy and higher tempco for lower cost and identical packaging/functionality; versus TLV3702IDR+REF3025, it reduces component count by 1, eliminates reference matching error, and cuts PCB area by ~30%.

FAQ
What is the reference voltage tolerance and temperature coefficient of the MAX9053BEUB?
The MAX9053BEUB features a 2.500V precision reference with ±1% initial accuracy (B grade) and a maximum temperature coefficient of 100ppm/°C over –40°C to +85°C. This specification ensures predictable reference drift in industrial environments, making the MAX9053BEUB suitable for applications where moderate accuracy suffices and cost optimization is prioritized over metrology-grade stability.
Can the MAX9053BEUB operate from a 3.0V supply, and what is its supply current at that voltage?
Yes, the MAX9053BEUB operates from 2.7V to 5.5V, so 3.0V is fully supported. At VCC = 3.0V and TA = +25°C, the typical supply current is 55µA - matching the value specified at 2.7V. This ultra-low quiescent current enables multi-year battery life in always-on sensor nodes powered by CR2032 or similar cells.
Does the MAX9053BEUB require an external capacitor on the REF pin for stability?
No, the MAX9053BEUB's 2.500V reference is internally compensated and stable with 0–4.7nF capacitive loads on the REF pin. An external capacitor is optional and recommended only in transient-heavy applications (e.g., switching power supply monitoring) to reduce overshoot; omitting it simplifies layout and reduces BOM count without compromising stability.
What are the absolute maximum ratings for the input pins of the MAX9053BEUB?
The MAX9053BEUB input pins (IN+, IN−) tolerate voltages from (VEE − 0.3V) to (VCC + 0.3V). Exceeding these limits risks latch-up or permanent damage. The device's rail-to-rail input stage extends the useful common-mode range to VEE − 0.25V to VCC + 0.25V under normal operation, but absolute ratings define safe survival limits, not functional boundaries.
How does the internal hysteresis of the MAX9053BEUB improve noise immunity in sensor applications?
The MAX9053BEUB incorporates ±3mV internal hysteresis, creating a 6mV dead band between rising and falling output transitions. This prevents rapid toggling (chatter) when input signals hover near the threshold due to noise - critical for reliable detection of slow-varying sensor outputs like thermistors or strain gauges without adding external positive-feedback resistors.
