Product details
Overview
The MAX9030AUT-T from Maxim Integrated is a single, rail-to-rail output comparator with shutdown control, optimized for +2.5V to +5.5V single-supply operation. It delivers 188ns propagation delay, 35μA supply current per comparator, 4mV internal hysteresis, and operates across -40°C to +125°C - ideal for battery-powered portable systems requiring low power and compact footprint.
For engineers reviewing the MAX9030AUT-T datasheet, MAX9030AUT-T pinout, MAX9030AUT-T application, or MAX9030AUT-T equivalent, key selection criteria include shutdown current (0.05μA), input common-mode range (VSS to VDD – 1.1V), rail-to-rail output swing, hysteresis immunity, and SOT23-6 package compatibility in space-constrained designs.
Technical Context
The MAX9030AUT-T implements a CMOS comparator core with internal 4mV hysteresis to prevent oscillation on slow-moving inputs. Its input stage supports common-mode voltages from ground to within 1.1V of VDD, enabling direct interfacing with sensors and ADC references without level-shifting.
The output stage is designed to minimize switching current transients, eliminating supply rail glitches during transitions. Shutdown is controlled by a high-impedance SHDN pin with logic thresholds at 0.3×VDD (low) and 0.7×VDD (high), reducing quiescent current to 0.05μA while placing the output in high-impedance state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V single supply - enables direct use with Li-ion, 3.3V, and 5V rails without regulation. |
| Propagation Delay | 188ns at VOD = 100mV - supports fast threshold detection in real-time sensor monitoring. |
| Supply Current | 35μA typical per comparator - extends battery life in always-on portable devices. |
| Shutdown Current | 0.05μA typical - reduces system standby power to nanoampere levels. |
| Hysteresis | 4mV built-in - provides noise immunity without external feedback components. |
| Input Common-Mode Range | VSS to (VDD – 1.1V) - accommodates ground-referenced signals and mid-supply thresholds. |
| Rail-to-Rail Output | Swings within 2mV of VSS/VDD at 10μA - ensures full logic-level compatibility with MCU GPIOs. |
Pinout & Package
The MAX9030AUT-T is housed in a 6-pin SOT23 package (package code U6SN+1), with 1.3mm × 2.2mm footprint and 0.95mm height - compatible with standard pick-and-place and reflow processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Negative supply (ground); requires local 0.1µF bypass to minimize noise coupling. |
| 2 | OUT | Open-drain–compatible rail-to-rail output; sinks up to 4mA, sources 10µA. |
| 3 | IN− | Inverting input; supports common-mode range down to VSS and up to VDD − 1.1V. |
| 4 | SHDN | Active-low shutdown control; high-impedance input draws ≤0.1μA, logic-low ≤0.3×VDD. |
| 5 | IN+ | Noninverting input; matched bias current (8nA typ.) enables precision threshold sensing. |
| 6 | VDD | Positive supply; must be bypassed with 0.1µF capacitor close to pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low shutdown current | 0.05μA enables multi-year battery life in intermittent-sensing applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3601DBVR | No shutdown; 220ns delay; 65μA supply current; 2.7V–5.5V range. | Lacks low-power shutdown - unsuitable for battery-critical wake-on-event systems. | Select when higher speed tolerance and no shutdown control are acceptable. |
| LMV7215M5X | Includes shutdown; 200ns delay; 80μA supply current; 2.7V–5.5V range; no built-in hysteresis. | Requires external hysteresis resistors; higher quiescent current reduces battery runtime. | Select when board area permits external feedback and faster propagation is prioritized over ultra-low power. |
Compared with TLV3601DBVR and LMV7215M5X, the MAX9030AUT-T uniquely combines sub-μA shutdown, built-in hysteresis, and 188ns delay in a 6-pin SOT23 - making it optimal for space- and energy-constrained portable sensing nodes where reliability and minimal BOM count are critical.

FAQ
What is the shutdown current specification for the MAX9030AUT-T?
The MAX9030AUT-T draws a typical shutdown current of 0.05μA when the SHDN pin is held at ≤0.3×VDD. This ultra-low leakage enables multi-year operation from coin-cell batteries in infrequently activated systems. The MAX9030AUT-T maintains this spec across its full -40°C to +125°C temperature range, ensuring consistent low-power behavior in harsh environments.
Does the MAX9030AUT-T require external hysteresis resistors?
No, the MAX9030AUT-T integrates 4mV of internal hysteresis, eliminating the need for external positive-feedback resistors in most noise-prone applications. This simplifies layout, reduces BOM count, and improves consistency across production units. External hysteresis can still be added if wider thresholds are required, but the MAX9030AUT-T functions reliably out-of-the-box for typical sensor interface tasks.
What is the input common-mode voltage range of the MAX9030AUT-T?
The MAX9030AUT-T supports an input common-mode voltage range from VSS (ground) to VDD – 1.1V. This allows direct interfacing with ground-referenced sensors (e.g., thermistors, photodiodes) and mid-supply references without level-shifting circuitry. At VDD = 3.3V, the upper limit is 2.2V - sufficient for most analog front-end signal conditioning stages.
Can the MAX9030AUT-T operate from a 2.5V supply?
Yes, the MAX9030AUT-T is fully specified for operation from +2.5V to +5.5V single supply. At 2.5V, it maintains 188ns propagation delay (typical), 35μA supply current, and rail-to-rail output swing - enabling compatibility with modern ultra-low-voltage microcontrollers and energy-harvesting systems. All electrical characteristics in the datasheet are guaranteed across this entire voltage range.
What package type is used for the MAX9030AUT-T?
The MAX9030AUT-T uses a 6-pin SOT23 package (package code U6SN+1), measuring 1.3mm × 2.2mm with 0.95mm height. It features gull-wing leads compatible with standard reflow soldering and automated assembly. The "T" suffix denotes tape-and-reel packaging for surface-mount production, and the "+" indicates RoHS-compliant, lead-free construction.
