Product details
Overview
MAX40008ANT+ from Analog Devices is a single-channel micro-power comparator with open-drain output, rail-to-rail inputs, 220ns propagation delay (L→H, MAX40009), and 12μA supply current at +25°C. It operates from 1.7V to 5.5V and features internal 3mV hysteresis, −40°C to +125°C automotive temperature range, and 0.73mm × 1.1mm 6-bump wafer-level package - ideal for battery-powered level translation and threshold detection in space-constrained portable systems.
For engineers reviewing the MAX40008ANT+ datasheet, MAX40008ANT+ pinout, MAX40008ANT+ application, or MAX40008ANT+ equivalent, this page delivers verified electrical parameters, WLP-6 terminal mapping, shutdown behavior, input offset voltage (±0.5mV typ), and design-critical trade-offs between open-drain flexibility and propagation delay vs. overdrive.
Technical Context
The MAX40008ANT+ implements a low-voltage CMOS comparator core with integrated 3mV hysteresis and active-low shutdown control (SHDN). Its rail-to-rail input stage supports common-mode voltages from −0.2V to VDD + 0.2V, and its open-drain output tolerates up to 6V above GND independent of VDD - enabling bidirectional level shifting across mismatched supply domains.
Supply current remains ≤17μA over full temperature range (−40°C to +125°C), while propagation delay varies with overdrive: 650ns (L→H) and 235ns (H→L) at 100mV overdrive with 39kΩ pullup, confirming its optimized use in low-speed precision thresholding rather than high-frequency window detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.7V to 5.5V - supports direct operation from 1.8V, 2.5V, 3.3V, and 5V rails without external regulation. |
| Supply Current (Typ) | 12μA at +25°C - enables multi-year battery life in always-on sensor monitoring nodes. |
| Propagation Delay (H→L) | 235ns at 100mV overdrive - defines minimum pulse width resolution for edge-triggered wake-up circuits. |
| Input Offset Voltage (Max) | ±5mV over −40°C to +125°C - sets worst-case threshold error in precision voltage discrimination. |
| Input Hysteresis | 3mV - prevents chatter on slow-moving signals like thermistor outputs or filtered sensor data. |
| Shutdown Current | 1μA max over temperature - reduces system standby power by >99% versus active mode. |
| Output Voltage Range | OUT to GND: −0.3V to +6V - allows pullup to higher-voltage logic domains (e.g., 3.3V device driving 1.8V input). |
Pinout & Package
MAX40008ANT+ uses a 0.73mm × 1.1mm, 0.35mm pitch, 6-bump wafer-level package (WLP-6, package code N60D1+1), optimized for ultra-dense PCB layouts in mobile and wearables.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | IN+ | Non-inverting input; accepts rail-to-rail common-mode signals from −0.2V to VDD + 0.2V. |
| A2 | VDD | Positive supply input; requires local 0.1μF bypass capacitor to GND for noise immunity. |
| B1 | IN− | Inverting input; matched to IN+ for balanced hysteresis band centering. |
| A3 | OUT | Open-drain output; must be pulled up externally - supports voltage translation beyond VDD. |
| B2 | SHDN | Active-low shutdown control; <0.55V disables comparator, >1.3V enables operation. |
| B3 | GND | Signal and power return; connects to system ground plane for stable reference. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Enables accurate threshold detection across full supply range - critical for low-VDD battery monitoring. |
| Integrated 3mV hysteresis | Eliminates need for external positive feedback resistors in noisy environments like motor control feedback paths. |
| Open-drain output with 6V absolute max rating | Permits level translation between disparate logic families (e.g., 3.3V MCU sensing 1.2V analog signal). |
| 12μA typical supply current | Reduces thermal load and extends runtime in coin-cell–powered IoT endpoints. |
| −40°C to +125°C operating range | Validated for under-hood automotive sensors and industrial field devices without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7011DBVR | Push-pull output; no open-drain capability; 360ns propagation delay; 650nA quiescent current. | Lacks voltage translation flexibility; suited for same-rail logic interfacing only. | Select TLV7011DBVR when output drive strength and minimal external components outweigh level-shifting needs. |
| MAX9062AXK+T | Higher supply current (35μA); 115ns propagation delay; SOT23-6 package only; no shutdown pin. | Optimized for speed over power; lacks shutdown control for ultra-low-power sleep modes. | Choose MAX9062AXK+T when sub-200ns response is mandatory and continuous operation is acceptable. |
Compared with TLV7011DBVR and MAX9062AXK+T, the MAX40008ANT+ uniquely balances ultra-low 12μA supply current, open-drain output for cross-rail interfacing, and integrated hysteresis - making it the only option among the three that supports both battery longevity and flexible voltage domain bridging in a single 0.73mm × 1.1mm footprint.

FAQ
What is the maximum allowable voltage on the OUT pin of the MAX40008ANT+?
The MAX40008ANT+ OUT pin supports −0.3V to +6V relative to GND, independent of VDD. This allows safe connection to pullup voltages up to 6V - for example, using a 3.3V-powered MAX40008ANT+ to drive a 5V logic input via external resistor. Exceeding +6V risks permanent damage per Absolute Maximum Ratings.
Does the MAX40008ANT+ require an external pullup resistor on the OUT pin?
Yes - the MAX40008ANT+ has an open-drain output and requires an external pullup resistor to establish a valid HIGH logic level. The datasheet recommends 39kΩ when pulling up to 3.3V; value scales inversely with target voltage and load capacitance. No pullup is needed if only LOW-active signaling is used.
How does the internal hysteresis of the MAX40008ANT+ affect threshold accuracy?
The MAX40008ANT+ features 3mV internal hysteresis centered around its input offset voltage (±0.5mV typ). This creates distinct upper and lower trip points, preventing oscillation on slow or noisy inputs - but introduces a 3mV uncertainty window where transitions are undefined. For precise single-threshold detection, external hysteresis or post-processing may be required.
Can the MAX40008ANT+ operate from a 1.7V supply while maintaining full specification?
Yes - the MAX40008ANT+ is fully specified from 1.7V to 5.5V. At 1.7V, it maintains rail-to-rail input range (0V to 1.7V), 17μA max supply current over temperature, and functional shutdown control. Propagation delay increases slightly (e.g., 235ns H→L remains valid), and VOL rises to 0.4V at 1.6mA sink current.
What is the purpose of the SHDN pin on the MAX40008ANT+ and how should it be driven?
The SHDN pin is an active-low enable input: logic LOW (<0.55V) places MAX40008ANT+ in shutdown mode (IDD ≤1μA), while logic HIGH (>1.3V) enables normal operation. It must be driven by a clean digital signal - floating or unterminated SHDN causes undefined behavior. Internal 1μA leakage limits pullup requirements to ≥1MΩ if actively driven.
