Product details
Overview
MAX40008ANT+T from Analog Devices is a single micro-power comparator with open-drain output, rail-to-rail inputs, and shutdown control-designed for low-voltage battery-powered systems. It operates from 1.7V to 5.5V, consumes only 12μA (typ) supply current at +25°C, achieves 220ns propagation delay (L→H, MAX40009 reference), and features 0.5mV (typ) input offset voltage with 3mV internal hysteresis. Its 6-bump WLP package (0.73mm × 1.1mm) supports space-constrained portable electronics.
For engineers reviewing the MAX40008ANT+T datasheet, MAX40008ANT+T pinout, MAX40008ANT+T application, or MAX40008ANT+T equivalent, key selection criteria include open-drain output compatibility with level translation up to 6V above GND, -40°C to +125°C automotive-grade operation, shutdown quiescent current ≤1μA, and verified 220ns propagation delay under 100mV overdrive conditions.
Technical Context
The MAX40008ANT+T implements a precision comparator core with rail-to-rail input stage extending 200mV beyond each supply rail, enabling accurate threshold detection across full VDD range. Its internal 3mV hysteresis band eliminates oscillation on slow-moving or noisy inputs without external components.
Shutdown functionality is implemented via active-low SHDN pin, reducing supply current to ≤1μA over temperature while preserving fast wake-up (<50μs power-up time). The open-drain output supports pull-up to voltages up to 6V (absolute max), independent of VDD, making it suitable for bipolar-to-single-ended conversion and multi-supply logic interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.7V to 5.5V - enables direct operation from 1.8V, 2.5V, 3V, and 5V system rails without regulation. |
| Supply Current (Active) | 12μA (typ) at +25°C - ensures >1-year battery life in always-on sensor monitoring applications. |
| Supply Current (Shutdown) | ≤1μA over -40°C to +125°C - guarantees ultra-low standby power for intermittent wake-up systems. |
| Propagation Delay | 220ns (L→H, 100mV overdrive, MAX40009 reference) - provides timing-critical response for high-speed window detection. |
| Input Offset Voltage | ±0.5mV (typ), ±5mV (max) over temp - supports sub-millivolt threshold accuracy in precision voltage monitoring. |
| Input Hysteresis | 3mV (typ) - prevents chatter on noisy or slowly ramping signals without external feedback. |
| Rail-to-Rail Inputs | Common-mode range extends -0.2V to VDD+0.2V - allows direct sensing of signals near supply rails. |
| Output Type | Open-drain - enables level translation between mismatched voltage domains (e.g., 3.3V logic driving 1.8V inputs). |
Pinout & Package
MAX40008ANT+T uses a 6-bump wafer-level package (WLP), 0.73mm × 1.1mm, 0.35mm pitch, top-mark "+3", RoHS-compliant. Package outline number 21-100086; land pattern per Application Note 1891.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | IN+ | Non-inverting input - accepts rail-to-rail analog signals; referenced to GND for threshold comparison. |
| A2 | VDD | Positive supply input - requires local 0.1μF bypass capacitor to GND for stable operation. |
| B1 | IN- | Inverting input - used with IN+ to define comparator trip point; supports differential or single-ended configurations. |
| A3 | OUT | Open-drain output - must be pulled up externally; supports voltages up to 6V above GND, independent of VDD. |
| B2 | SHDN | Active-low shutdown control - drives device into <1μA quiescent state when logic low; no external pullup required. |
| B3 | GND | Signal and power return - shared reference for all inputs, outputs, and supply; critical for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 12μA typical at +25°C - minimizes battery drain in portable medical and IoT sensors. |
| Integrated 3mV hysteresis | Eliminates need for external positive feedback resistors in threshold-detection circuits. |
| Open-drain output with 6V absolute max rating | Enables robust level translation between 1.8V, 2.5V, 3.3V, and 5V logic domains without clamping diodes. |
| Rail-to-rail input common-mode range | Supports direct interface to ADC references, battery monitors, and sensor amplifiers operating near supply rails. |
| Automotive temperature grade | -40°C to +125°C operation - qualified for under-hood and infotainment subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3604DBVR | Push-pull output, no shutdown, 170ns propagation delay, 65μA supply current | Lacks shutdown and open-drain flexibility; higher power draw limits battery life | Select when push-pull drive and faster switching outweigh power and interface constraints |
| MAX40009ANT+T | Same package, pinout, and specs except push-pull output; identical supply current and propagation delay | Cannot perform level translation beyond VDD; requires external pullup for wired-OR logic | Select when output loading demands rail-to-rail sourcing/sinking without external components |
Compared with TLV3604DBVR and MAX40009ANT+T, the MAX40008ANT+T uniquely combines ultra-low 12μA supply current, integrated shutdown, and open-drain output rated to 6V-making it the only option among the three for energy-sensitive, multi-supply level-shifting applications requiring automotive temperature support.

FAQ
What is the maximum allowable voltage on the OUT pin of MAX40008ANT+T?
The MAX40008ANT+T OUT pin is rated for voltages up to 6V above GND, independent of VDD. This allows safe use with pull-up resistors connected to higher-voltage rails (e.g., 5V pullup while VDD = 1.8V), enabling robust level translation. Exceeding 6V absolute maximum may cause permanent damage, per Absolute Maximum Ratings.
Does MAX40008ANT+T require an external pull-up resistor on the OUT pin?
Yes, MAX40008ANT+T has an open-drain output and requires an external pull-up resistor to establish a valid HIGH logic level. A 39kΩ resistor to VDD (or another compatible voltage up to 6V) is recommended per the datasheet. Without pull-up, the output remains floating and cannot drive HIGH.
Can MAX40008ANT+T operate from a 1.7V supply and still meet its specified propagation delay?
Yes, MAX40008ANT+T is fully specified from 1.7V to 5.5V. At VDD = 1.7V, propagation delay increases to 235ns (H→L) and 650ns (L→H, with 39kΩ pullup), per Electrical Characteristics table. The 220ns figure applies to MAX40009 under 100mV overdrive; MAX40008 L→H delay is slower due to pullup-dependent rise time.
What is the function of the SHDN pin on MAX40008ANT+T, and what voltage levels activate it?
The SHDN pin on MAX40008ANT+T is an active-low shutdown control. It activates shutdown (reducing supply current to ≤1μA) when driven to ≤0.55V (logic low). The device operates normally when SHDN is ≥1.3V (logic high). No external pullup is required, and the pin draws ≤1μA in either state.
Is MAX40008ANT+T pin-compatible with MAX40009ANT+T?
Yes, MAX40008ANT+T and MAX40009ANT+T share identical 6-bump WLP package, pinout, and footprint (outline 21-100086). They differ only in output stage: MAX40008ANT+T has open-drain, while MAX40009ANT+T has push-pull. Board designs can swap them with only minor schematic changes to the output network.
