Product details
Overview
MAX40005ANS+T from Analog Devices is a nanoPower, inverting-input, push-pull output comparator with internal 0.5V reference voltage, housed in a 0.73mm × 0.73mm 4-bump wafer-level package (WLP). It operates from 1.7V to 5.5V supply, draws only 500nA typical supply current, supports input voltages from 0.1V to 5.5V independent of supply, and is fully specified over –40°C to +125°C for automotive and portable electronics monitoring.
For engineers reviewing the MAX40005ANS+T datasheet, MAX40005ANS+T pinout, MAX40005ANS+T application, or MAX40005ANS+T equivalent, this page delivers verified electrical parameters, WLP package layout, inverting comparator behavior with factory-trimmed 0.5V reference, propagation delay (9µs high-to-low), and design-critical thermal and RF immunity characteristics.
Technical Context
The MAX40005ANS+T implements an inverting-input comparator architecture with internal temperature-compensated 0.5V reference (±15mV max deviation at +25°C, ±37mV over full temperature range). Its input stage allows VIN to exceed VCC by several volts without clamping, enabling robust signal detection in mixed-voltage systems.
It features push-pull output capable of sourcing 1mA (VOH = VCC – 0.4V) and sinking 2mA (VOL = 0.4V), eliminating external pull-up resistors. Internal 8mV hysteresis ensures noise-immune switching, and ultra-low 500nA quiescent current enables always-on battery monitoring in space-constrained applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.7V to 5.5V - compatible with 1.8V, 2.5V, 3.3V, and 5V logic rails without level shifting |
| Quiescent Supply Current | 0.5µA typical - preserves battery life in continuously active sensing nodes |
| Internal Reference Voltage | 0.5V ±15mV (typ) at +25°C - factory-trimmed, eliminates external reference component and PCB area |
| Propagation Delay | 9µs (high-to-low), 25µs (low-to-high @100mV overdrive) - enables fast response in threshold-detection circuits |
| Input Voltage Range | 0.1V to 5.5V, independent of supply - supports rail-to-rail input sensing even with sub-1.8V supplies |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial, and extended-life portable devices |
| Output Type | Push-pull - drives CMOS/TTL loads directly without external pull-up resistor |
Pinout & Package
MAX40005ANS+T uses a 4-bump wafer-level package (WLP), 0.73mm × 0.73mm footprint, 0.35mm pitch, RoHS-compliant, top-marked "+L". Thermal resistance θJA = 104.41°C/W on a 4-layer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | OUT | Push-pull output - asserts low when VIN > VREF_INT (0.5V); sinks 2mA / sources 1mA; no external pull-up required |
| A2 | IN | Inverting input - comparison node where input voltage is compared against internal 0.5V reference |
| B1 | VCC/REF | Supply and reference input - powers device and sets bias for internal reference; bypass with 0.1µF capacitor to GND |
| B2 | GND | Analog ground - return path for supply, reference, and output; must be low-impedance for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| Inverting input with internal 0.5V reference | Enables direct low-side voltage threshold detection (e.g., battery undervoltage alarm at 0.5V scaled input) |
| 0.73mm × 0.73mm 4-bump WLP | Footprint smaller than two 0402 passives - ideal for wearables, hearing aids, and ultra-compact IoT sensors |
| 500nA supply current (typ) | Extends coin-cell battery life to multi-year operation in always-on wake-up or fault-monitoring circuits |
| Input voltage exceeds VCC capability | Allows direct connection of higher-voltage analog signals (e.g., 3.3V sensor output into 1.8V-powered system) |
| 8mV internal hysteresis | Prevents chatter during slow-moving or noisy input transitions without requiring external feedback components |
Applications
| Battery Undervoltage Detection | Low-Power Sensor Wake-Up |

IC Role / Device Role / Timing Role: Compares conditioned analog signal against internal 0.5V reference; drives buzzer or LED driver via push-pull output. Use Value: Push-pull output eliminates need for external transistor or pull-up, reducing solution size and component count in space-limited enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX40005AUK+T | Same electrical specs and 0.5V internal reference, but in 5-pin SOT23 package (2.9mm × 1.6mm) | Requires larger PCB area; better thermal dissipation (θJA = 255.9°C/W vs. 104.4°C/W) and manual solderability | Select for prototyping, repairability, or thermal margin needs where WLP assembly is impractical |
| TLV7031DBVR | Push-pull, inverting comparator with 0.5V reference; 650nA IQ; SOT23-5; wider supply range (1.6V–6.5V) | Larger package, higher quiescent current, no WLP option; not AEC-Q100 qualified | Select for non-automotive cost-sensitive designs needing second-source availability and broader supply flexibility |
Compared with MAX40005ANS+T, MAX40005AUK+T offers identical functionality in a larger, more manufacturable package, while TLV7031DBVR provides a non-automotive alternative with higher IQ but greater supply range-neither is pin-compatible, and both require layout changes due to different footprints and thermal profiles.

FAQ
What is the internal reference voltage of the MAX40005ANS+T?
The MAX40005ANS+T features a factory-trimmed internal reference voltage of 0.5V, with a typical tolerance of ±15mV at +25°C and ±37mV over the full –40°C to +125°C operating range. This reference is used as the comparison threshold for the inverting input, and no external reference is required for basic operation of the MAX40005ANS+T.
Does the MAX40005ANS+T require an external pull-up resistor on its output?
No, the MAX40005ANS+T does not require an external pull-up resistor because it features a push-pull output stage. The output can actively drive high (up to VCC – 0.4V at 1mA) and low (down to 0.4V at 2mA), enabling direct interface with CMOS or TTL inputs without additional components - a key advantage over open-drain comparators like the MAX40003ANS+T.
What package type is used for the MAX40005ANS+T?
The MAX40005ANS+T is packaged in a 4-bump wafer-level package (WLP) measuring 0.73mm × 0.73mm with 0.35mm pitch. It is RoHS-compliant (indicated by the "+" suffix), top-marked "+L", and designed for automated reflow assembly on fine-pitch PCBs. This ultra-small footprint is significantly smaller than the SOT23 variant (MAX40005AUK+T).
Can the MAX40005ANS+T operate with input voltages higher than its supply voltage?
Yes, the MAX40005ANS+T supports input voltages up to 6V (absolute maximum) regardless of VCC, thanks to its innovative input-stage architecture without ESD diode clamps to VCC. This allows direct interfacing of higher-voltage signals (e.g., 3.3V sensor output) into a 1.8V-powered system using the MAX40005ANS+T - a capability not found in conventional comparators.
What is the propagation delay of the MAX40005ANS+T, and how does it vary with overdrive?
The MAX40005ANS+T exhibits 9µs propagation delay for high-to-low transitions and 25µs for low-to-high transitions under 100mV input overdrive. Delay decreases with higher overdrive: at 200mV overdrive, low-to-high delay drops to ~15µs. These values are guaranteed over –40°C to +125°C and enable precise timing in fast-response threshold detection circuits using the MAX40005ANS+T.
