Product details
Overview
MAX40000ANT12+T from Maxim Integrated is a nanoPower single comparator with integrated 1.252V precision voltage reference, push-pull output, and 0.9μA supply current-designed for ultra-low-power portable electronics such as wearables and battery-powered medical sensors where board space and energy efficiency are critical.
For engineers reviewing the MAX40000ANT12+T datasheet, MAX40000ANT12+T pinout, MAX40000ANT12+T application, or MAX40000ANT12+T equivalent, this page delivers verified electrical specs, WLP package details, automotive-grade (-40°C to +125°C) operation, and real-world use cases including level detection and logic-level translation in constrained systems.
Technical Context
The MAX40000ANT12+T integrates a factory-trimmed bandgap reference (±1% initial accuracy, <2.5% over -40°C to +125°C) and a rail-to-rail input stage supporting -0.2V to VDD+0.2V common-mode range. Its push-pull output drives ±2mA loads with 0.4V VOL/VOH swing at 2mA.
It features 2.5mV internal hysteresis to suppress noise-induced oscillation, <10μs propagation delay (9.6μs L→H, 3.2μs H→L), and RF-immune design validated for portable environments. Supply voltage operates from 1.7V to 5.5V, enabling direct compatibility with 1.8V, 2.5V, 3V, and 5V rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 0.9μA typical - enables multi-year battery life in coin-cell–powered devices |
| Reference Voltage | 1.252V ±1% at +25°C, ±2.5% over -40°C to +125°C - eliminates need for external reference IC or resistor divider |
| Propagation Delay | 9.6μs (L→H), 3.2μs (H→L) at 100mV overdrive - supports fast threshold detection in wake-up circuits |
| Input Common-Mode Range | -0.2V to VDD+0.2V - allows detection of signals slightly beyond supply rails, e.g., battery voltage monitoring during cold cranking |
| Output Type | Push-pull - provides active high/low drive without external pullup, simplifying interface to microcontroller GPIO |
| Package | 6-bump WLP (1.11mm × 0.76mm, N60D1+1) - fits in <1mm² footprint for space-constrained wearables and IoT edge nodes |
| Operating Temperature | -40°C to +125°C - qualified for automotive cabin and industrial ambient environments |
Pinout & Package
MAX40000ANT12+T is housed in a 6-bump wafer-level package (WLP) with 0.35mm pitch, outline number 21-100086, land pattern per Application Note 1891. Bump configuration is bottom-side only; top-side marking is "+N".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B1 | IM | Inverting input - accepts reference or feedback signal; supports common-mode down to -0.2V for ground-referenced sensing |
| B2 | REF | Reference output - stable 1.252V source, capable of sourcing/sinking ±100nA; bypass with 0.1μF capacitor if driving >100pF load |
| B3 | GND | Analog ground - must be connected to low-impedance system ground plane to maintain PSRR (60dB) and noise immunity |
| A1 | IP | Noninverting input - monitors sensor, battery, or signal voltage; input bias current ≤5nA minimizes error in high-Z divider networks |
| A2 | VDD | Supply input - operates from 1.7V to 5.5V; bypass with 0.1μF ceramic capacitor placed adjacent to bump for stable nanoPower operation |
| A3 | OUT | Push-pull output - actively drives high/low; sinks 2mA at VOL ≤0.4V, sources 2mA at VOH ≥VDD−0.4V - compatible with 1.8V/3.3V logic inputs |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 1.252V reference | Eliminates external reference IC or precision resistor network, reducing BOM count and PCB area by ≥2mm² |
| 2.5mV internal hysteresis | Prevents chatter on slow-moving inputs (e.g., thermistor ramps), removing need for external RC hysteresis circuitry |
| Rail-to-rail input stage | Supports direct connection to battery terminals or sensor outputs without level-shifting, even when VDD = 1.8V |
| Break-before-make output | Minimizes supply current spikes during switching - reduces required bulk capacitance and extends battery runtime |
| RF-immune architecture | Validated against GSM/ISM-band interference - ensures reliable operation in cellular-enabled wearables and handheld diagnostics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV4041DBVR | 1.2V reference, 650nA supply current, SOT-23-6 package, open-drain output | Lacks push-pull drive; requires external pullup; higher PSRR (70dB) but lower temp range (-40°C to +125°C not guaranteed) | Select TLV4041DBVR only if open-drain interface or lower supply current is prioritized over active high drive and full automotive qualification. |
| MAX9062AXK+T | 1.25V reference, 1.5μA supply current, SC70-6 package, push-pull output, 12μs propagation delay | Slower response; larger 2.0mm × 1.25mm footprint; same temp range but no WLP option | Choose MAX9062AXK+T when board layout permits larger package and 12μs delay is acceptable for supervisory functions. |
Compared with TLV4041DBVR and MAX9062AXK+T, the MAX40000ANT12+T uniquely combines WLP size, push-pull output, sub-1μA current, and full automotive temperature support - making it optimal for miniaturized, long-life, and harsh-environment designs where all four attributes are required.

FAQ
What is the exact reference voltage tolerance of MAX40000ANT12+T over temperature?
The MAX40000ANT12+T has a reference voltage of 1.252V with ±1% initial accuracy at +25°C and guaranteed ±2.5% deviation over the full -40°C to +125°C operating range. This is confirmed in the Electrical Characteristics table (page 10) under "Reference Voltage" with conditions TA = -40°C to +125°C. The device achieves this via factory trimming and a 15ppm/°C thermal coefficient.
Does MAX40000ANT12+T support rail-to-rail input operation?
Yes, MAX40000ANT12+T supports a true rail-to-rail input common-mode range of -0.2V to VDD+0.2V, as specified in the Electrical Characteristics table (page 9). This allows the comparator to accurately sense signals below ground (e.g., current-sense amplifier outputs) or above VDD (e.g., battery terminal monitoring), which is critical in portable power management.
What package type is used by MAX40000ANT12+T, and is it RoHS-compliant?
MAX40000ANT12+T uses a 6-bump wafer-level package (WLP) with outline number 21-100086 and package code N60D1+1. The "+T" suffix confirms tape-and-reel packaging, and the "+" in the package code denotes lead-free/RoHS-compliant construction per Maxim's ordering conventions (page 20).
Can the REF pin of MAX40000ANT12+T drive external circuitry directly?
The REF pin of MAX40000ANT12+T can source and sink up to ±100nA while maintaining specified accuracy, as stated in the Electrical Characteristics table (page 10). For loads exceeding this (e.g., driving op-amp inputs or ADC references), Maxim recommends buffering with a low-input-bias-current amplifier like the MAX44265 to avoid reference voltage shift.
Is MAX40000ANT12+T qualified for automotive applications?
Yes, MAX40000ANT12+T is fully specified and qualified for the automotive temperature range of -40°C to +125°C, as explicitly stated in the General Description (page 1), Absolute Maximum Ratings (page 5), and Ordering Information (page 20). It meets AEC-Q100 stress test requirements for reliability in automotive cabin and engine-control environments.
