Product details
Overview
The MAX9030AXT-T from Maxim Integrated is a single, rail-to-rail output comparator with shutdown control, designed for low-power, single-supply operation from +2.5V to +5.5V. It delivers 188ns propagation delay, 4mV internal hysteresis, 35μA supply current per comparator, and operates across -40°C to +125°C - ideal for battery-powered portable systems requiring precise threshold detection with minimal quiescent power.
For engineers reviewing the MAX9030AXT-T datasheet, MAX9030AXT-T pinout, MAX9030AXT-T application, or MAX9030AXT-T equivalent, key selection considerations include its 6-pin SC70 package, shutdown-enabled current reduction to 0.05μA, rail-to-rail output swing, input common-mode range extending to VDD − 1.1V, and immunity to phase reversal under overdriven inputs.
Technical Context
The MAX9030AXT-T implements a CMOS input stage with internal 4mV hysteresis to suppress noise-induced oscillation on slow-moving signals. Its output stage minimizes switching current transients, eliminating supply rail glitches during transitions.
Shutdown is controlled via a high-impedance SHDN pin with logic thresholds at 0.3×VDD (low) and 0.7×VDD (high); asserting SHDN to VSS places the device in ultra-low-current mode (0.05μA typ), disabling the output and placing it in high-impedance state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V single supply - enables direct integration into Li-ion and 3.3V/5V systems without level-shifting. |
| Propagation Delay | 188ns at VOD = 100mV - supports fast edge detection in sensor interfaces and digital line receivers. |
| Supply Current | 35μA typical active, 0.05μA typical shutdown - extends battery life in always-on monitoring applications. |
| Hysteresis | 4mV built-in - eliminates false triggering from EMI or signal noise without external components. |
| Input Common-Mode Range | VSS to VDD − 1.1V - allows direct sensing of ground-referenced signals up to near-rail levels. |
| Output Swing | Rail-to-rail - ensures full logic-level compatibility with downstream CMOS/TTL inputs. |
| Operating Temperature | -40°C to +125°C - qualified for automotive cabin and industrial embedded environments. |
Pinout & Package
The MAX9030AXT-T is housed in a RoHS-compliant, lead-free 6-pin SC70 package (package code X6SN+1, outline 21-0077), optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Negative supply reference; requires local 0.1µF bypass capacitor to minimize noise coupling. |
| 2 | OUT | Rail-to-rail CMOS output; high-impedance in shutdown mode; drives 4mA load with <400mV drop. |
| 3 | IN− | Inverting input; supports common-mode voltage up to VDD − 1.1V; 8nA max bias current. |
| 4 | SHDN | Active-high shutdown control; 0.1μA max input bias; logic low ≤ 0.3×VDD disables operation. |
| 5 | IN+ | Noninverting input; matched offset and hysteresis performance with IN−; no phase reversal on overdrive. |
| 6 | VDD | Positive supply; absolute max +6V; must be bypassed with 0.1µF capacitor close to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low shutdown current | 0.05μA typical - reduces system standby power by >99% versus active mode. |
| No phase reversal | Guaranteed under overdriven inputs - prevents erroneous output states during signal saturation. |
| Internal hysteresis | 4mV fixed - eliminates need for external positive feedback resistors in most threshold-detection designs. |
| Single-supply optimization | Operates down to +2.5V - compatible with coin-cell and single Li-ion battery systems. |
| Glitch-free output transitions | Minimized switching supply current - avoids interference with sensitive analog or RF circuitry on shared rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3691IDCKR | Lower supply current (320nA typ), no shutdown, 150ns delay, 1.8–5.5V range. | Lacks shutdown control; better suited for ultra-low-power always-on sensing, not duty-cycled systems. | Select when lowest possible active current is critical and shutdown is unnecessary. |
| LMV7215M5X | Higher speed (45ns), higher supply current (85μA), no shutdown, 2.7–5.5V range. | Optimized for high-speed window comparators; unsuitable for battery-sensitive shutdown use cases. | Select when sub-50ns response is required and power budget allows >2× current draw. |
Compared with TLV3691IDCKR and LMV7215M5X, the MAX9030AXT-T uniquely balances low active current (35μA), ultra-low shutdown current (0.05μA), and integrated hysteresis - making it optimal for intermittently powered, noise-prone threshold detection where both precision and energy efficiency are mandatory.

FAQ
What is the shutdown current specification for MAX9030AXT-T?
The MAX9030AXT-T draws 0.05μA typical supply current in shutdown mode when the SHDN pin is held at ≤ 0.3×VDD. This ultra-low leakage enables multi-year battery life in intermittent-sensing applications. The shutdown state also places the OUT pin in high-impedance, preventing loading of downstream circuits. Full specifications are confirmed across the -40°C to +125°C operating range.
Does MAX9030AXT-T support rail-to-rail output swing?
Yes, the MAX9030AXT-T provides true rail-to-rail output swing: VOH reaches within 2mV of VDD at 10μA sink/source, and VOL stays below 2mV above VSS under the same condition. This ensures reliable interfacing with 1.8V, 3.3V, and 5V logic families without level shifters. Performance is guaranteed over the full -40°C to +125°C temperature range and supply voltage span (+2.5V to +5.5V).
What is the input common-mode voltage range of MAX9030AXT-T?
The MAX9030AXT-T accepts input voltages from VSS (ground) up to VDD − 1.1V - for example, 0V to +4.4V at VDD = +5.5V. This extended range enables direct sensing of ground-referenced signals and partial-rail inputs without external biasing. The specification is guaranteed by CMRR testing and remains stable across temperature and supply variations.
How does the 4mV internal hysteresis function in MAX9030AXT-T?
The MAX9030AXT-T integrates 4mV of fixed hysteresis between its upper and lower trip points, eliminating external feedback components in most noise-prone applications. This hysteresis prevents output oscillation when input signals transition slowly or contain high-frequency noise. The value is defined as the differential voltage required to switch output states and is fully characterized across temperature and supply voltage.
Is MAX9030AXT-T pin-compatible with other comparators in the MAX903x family?
No - the MAX9030AXT-T uses a 6-pin SC70 package with SHDN functionality, while the MAX9031 (5-pin SC70/SOT23) lacks shutdown and has different pin count and assignment. Pinouts are not interchangeable; PCB layout must match the specific variant. The MAX9030AXT-T pin configuration is unique to its shutdown-enabled single-comparator variant and is documented in the official Maxim datasheet Figure "MAX9030 Pin Configurations".
