Product details
Overview
MAX40000ANT12+ from Maxim Integrated is a nanoPower single comparator with integrated 1.252V precision voltage reference, push-pull output, and 6-bump wafer-level package (WLP). It operates from 1.7V to 5.5V supply, draws only 0.9μA typical supply current, features 2.5mV internal hysteresis, and is fully specified over –40°C to +125°C for automotive-grade battery monitoring in space-constrained portable electronics.
For engineers reviewing the MAX40000ANT12+ datasheet, MAX40000ANT12+ pinout, MAX40000ANT12+ application, or MAX40000ANT12+ equivalent, key selection criteria include its 1.252V ±1% initial reference accuracy, 1.11mm × 0.76mm WLP footprint, sub-10μs propagation delay, RF-immune input stage, and compatibility with 1.8V/2.5V/3V/5V supply rails in ultra-low-power sensing systems.
Technical Context
The MAX40000ANT12+ integrates a bandgap-based voltage reference trimmed to ±1% at +25°C and <2.5% over –40°C to +125°C, with 15ppm/°C thermal drift and stability up to 100pF capacitive load. Its input stage supports common-mode range from –0.2V to VDD + 0.2V and exhibits 1–5nA input bias current across temperature.
The push-pull output delivers rail-to-rail swing with ±2mA drive capability, 0.4V VOL at 2mA sink and 0.4V VOH drop at 2mA source, and features break-before-make switching to minimize supply-current surges-critical for battery life in always-on detection circuits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40000AUT12+T | SOT23-6 package (2.9mm × 1.6mm), same electrical specs and 1.252V reference | Preferred where hand-soldering, thermal mass, or legacy footprint compatibility is required | Select when board assembly process favors leaded packages or thermal dissipation >347mW is needed |
| TLV4041DBVR | 1.2V reference (±1.5%), 1.2μA supply current, SOT23-6, no internal hysteresis | Requires external hysteresis network for noise immunity; lower reference accuracy impacts precision thresholding | Choose if cost sensitivity outweighs need for integrated hysteresis and tighter reference tolerance |

FAQ
What is the exact reference voltage tolerance of the MAX40000ANT12+ over temperature?
The MAX40000ANT12+ has a factory-trimmed reference voltage of 1.252V with ±1% initial accuracy at +25°C and guaranteed ±2.5% total error over the full –40°C to +125°C operating range. This includes contributions from initial trim, thermal drift (15ppm/°C), and line/load regulation effects per the datasheet Electrical Characteristics table.
Does the MAX40000ANT12+ require an external bypass capacitor on the REF pin?
Yes-the MAX40000ANT12+ REF pin must be bypassed with a 0.1μF ceramic capacitor to GND, placed as close as possible to the device. This ensures stability under capacitive loads up to 100pF and maintains RF immunity; omitting it risks reference noise coupling into the comparator input stage.
Can the MAX40000ANT12+ operate from a 1.8V supply while maintaining full specification?
Yes-the MAX40000ANT12+ is fully specified from 1.7V to 5.5V supply voltage. At 1.8V, all parameters-including 0.9μA supply current, 2.5mV hysteresis, 1.252V reference accuracy, and –0.2V to VDD + 0.2V input common-mode range-remain valid across –40°C to +125°C per the Absolute Maximum Ratings and Electrical Characteristics tables.
What is the maximum capacitive load the MAX40000ANT12+ REF output can drive?
The MAX40000ANT12+ REF output is stable with capacitive loads up to 100pF, as confirmed in the Electrical Characteristics table under "Capacitive Load Stability." Driving larger loads may cause oscillation or reference inaccuracy; for higher capacitance requirements, buffer the REF pin with a low-input-bias-current op amp such as the MAX44265.
Is the MAX40000ANT12+ pin-compatible with other variants in the MAX40000 family?
Yes-all MAX40000 variants (e.g., MAX40000ANT16+, MAX40000AUT12+) share identical 6-bump WLP or 6-pin SOT23 pinouts and terminal functions. The only differences are reference voltage value (1.252V, 1.66V, etc.) and package type; no PCB redesign is needed when substituting within the same package variant.
