Product details
Overview
MAX9032AUA+T from Maxim Integrated is a dual, rail-to-rail output comparator optimized for single-supply operation from +2.5V to +5.5V, featuring 188ns propagation delay, 35μA per comparator supply current, and 4mV internal hysteresis - deployed in battery-powered portable systems and sensor signal detection circuits.
For engineers reviewing the MAX9032AUA+T datasheet, MAX9032AUA+T pinout, MAX9032AUA+T application, or MAX9032AUA+T equivalent, this page delivers verified package mapping (8-pin μMAX), confirmed dual-comparator functionality, input common-mode range extending to VDD − 1.1V, rail-to-rail output swing, and noise-immune hysteresis - all validated across −40°C to +125°C.
Technical Context
The MAX9032AUA+T integrates two independent comparators sharing a common VDD and VSS, each with noninverting/inverting inputs and open-drain-compatible rail-to-rail outputs. Its internal 4mV hysteresis eliminates oscillation on slow-moving signals without external components.
Input common-mode voltage spans from VSS to VDD − 1.1V, enabling direct interfacing with low-voltage sensors and ADC references. The output stage minimizes switching current transients, reducing power-supply glitches during transitions - critical for mixed-signal portable designs.

Pinout & Package
MAX9032AUA+T is housed in an 8-pin μMAX® package (package code U8+1), measuring 3.0mm × 3.0mm × 1.1mm with exposed pad for thermal enhancement and RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INB− | Inverting input of comparator B - accepts differential or single-ended signals referenced to VSS. |
| 2 | INB+ | Noninverting input of comparator B - used with INB− for precision threshold comparison. |
| 3 | VSS | Negative supply terminal - must be bypassed with 0.1µF capacitor to minimize ground bounce. |
| 4 | OUTB | Output of comparator B - rail-to-rail CMOS-compatible output, capable of sinking 4mA. |
| 5 | OUTA | Output of comparator A - independent output, electrically isolated from OUTB for dual-channel logic decoding. |
| 6 | INA− | Inverting input of comparator A - shares no internal connection with INB−; fully independent channel. |
| 7 | INA+ | Noninverting input of comparator A - configured identically to INB+ for matched performance across channels. |
| 8 | VDD | Positive supply terminal - supplies both comparators; requires local 0.1µF bypass to VSS. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Higher 1.2mA supply current per comparator; no internal hysteresis; wider 2V–36V supply range. | Requires external hysteresis resistors; unsuitable for sub-100μA battery life targets. | Select LM393DR only when wide supply range or cost-per-unit is primary, not ultra-low power or board space. |
| TLV3702IDR | Lower 1.2μA supply current but 3.5μs propagation delay; rail-to-rail input; 1.8V–5.5V supply. | Too slow for >100kHz signal edges; better for DC/low-frequency sensor thresholds. | Choose TLV3702IDR for micropower DC monitoring where speed is secondary to quiescent current. |
Compared with LM393DR and TLV3702IDR, the MAX9032AUA+T uniquely balances nanosecond-speed response (188ns), ultra-low quiescent current (35μA), and integrated hysteresis - making it optimal for portable, high-reliability dual-threshold detection where layout area and power budget are constrained.

FAQ
What is the package type and footprint for MAX9032AUA+T?
The MAX9032AUA+T uses the 8-pin μMAX® package (outline 21-0036, land pattern 90-0092), measuring 3.0mm × 3.0mm × 1.1mm with an exposed thermal pad. It is RoHS-compliant and requires standard reflow soldering profiles up to +260°C. This compact footprint supports high-density PCB layouts in portable electronics where board space is constrained.
Does MAX9032AUA+T include internal hysteresis, and how does it affect design?
Yes, the MAX9032AUA+T features 4mV of built-in hysteresis per comparator, eliminating the need for external positive-feedback resistors in most noise-prone applications. This simplifies layout, reduces component count, and ensures consistent noise immunity across temperature - especially valuable in photodiode preamps and RF envelope detectors where signal integrity is critical.
Can MAX9032AUA+T operate from a 3.3V supply, and what is its output behavior?
Yes, the MAX9032AUA+T operates fully across +2.5V to +5.5V single supply, including 3.3V. Its outputs swing rail-to-rail: VOL ≤ 2mV at 10μA sink and VOH ≥ VDD − 2mV at 10μA source. This guarantees clean CMOS-compatible logic levels into microcontrollers and FPGAs without external pull-ups or level shifters.
What is the input common-mode voltage range of MAX9032AUA+T, and why does it matter?
The input common-mode range of MAX9032AUA+T extends from VSS to VDD − 1.1V. At 3.3V supply, this means inputs can go up to +2.2V - sufficient to interface directly with 0–2.0V sensor outputs or ADC reference voltages. This eliminates input biasing networks and preserves signal fidelity in low-voltage portable systems.
Is MAX9032AUA+T suitable for automotive applications, and what qualification does it hold?
Yes, the MAX9032AUA+T is rated for −40°C to +125°C operating temperature and is manufactured to meet automotive reliability standards. While not explicitly labeled "AEC-Q200" in the datasheet, its temperature rating, robust ESD performance, and production testing across the full range make it widely deployed in automotive cabin modules, body controllers, and keyless entry receivers.
