Product details
Overview
MAX9034AUD+T from Maxim Integrated is a quad low-power voltage comparator optimized for single-supply operation from +2.5V to +5.5V, featuring 188ns propagation delay, 35μA supply current per comparator, 4mV internal hysteresis, rail-to-rail output swing, and operation across -40°C to +125°C - deployed in battery-powered portable systems and sensor signal detection circuits.
For engineers reviewing the MAX9034AUD+T datasheet, MAX9034AUD+T pinout, MAX9034AUD+T application, or MAX9034AUD+T equivalent, key selection criteria include ultra-low quiescent current, guaranteed hysteresis for noise immunity, input common-mode range extending to VDD − 1.1V, TSSOP-14 package compatibility, and absence of phase reversal under overdrive.
Technical Context
The MAX9034AUD+T integrates four independent comparators sharing a common VDD and VSS supply, each with matched input offset voltage (±5mV max), ±60nA input offset current, and 100dB PSRR/CMRR at +5.5V. Its output stage minimizes switching current transients to suppress power-supply glitches.
Designed for single-supply use, it supports input common-mode voltages from VSS to VDD − 1.1V and delivers rail-to-rail output swing into 4mA loads with <400mV VOL/VOH drop. Propagation delay remains stable across 10mV–100mV input overdrive and 0–150pF capacitive load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V single supply - enables direct integration with Li-ion and 3.3V logic rails without level shifting. |
| Supply Current per Comparator | 35μA typical - allows continuous operation in multi-comparator sensor monitoring systems with sub-150μA total quiescent draw. |
| Propagation Delay | 188ns at 100mV overdrive - supports reliable timing discrimination for 5MHz digital line receivers and photodiode pulse detection. |
| Input Hysteresis | 4mV built-in - eliminates chatter on slow-moving signals like thermistor or potentiometer outputs without external feedback. |
| Input Common-Mode Range | VSS to VDD − 1.1V - accommodates ground-referenced sensors and rail-to-rail analog front-ends without attenuation. |
| Rail-to-Rail Output Swing | Within 400mV of rails at 4mA - ensures full logic-level compatibility with CMOS/TTL inputs across temperature and supply variation. |
| Operating Temperature | −40°C to +125°C - qualified for automotive cabin modules, industrial IoT edge nodes, and outdoor portable equipment. |
Pinout & Package
MAX9034AUD+T is housed in a 14-pin Thin Shrink Small Outline Package (TSSOP) with exposed pad, footprint code U14+1, outline 21-0066, and land pattern 90-0113 - designed for high-density PCB layouts with thermal performance suitable for continuous operation at +125°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTD | Comparator D open-drain output - requires external pull-up for logic-high assertion; compatible with mixed-voltage I/O domains. |
| 2 | IND− | Comparator D inverting input - accepts signals down to VSS; differential pair matched to IND+ for precision thresholding. |
| 3 | IND+ | Comparator D noninverting input - forms high-impedance sensing node; paired with IND− for configurable hysteresis. |
| 4 | VSS | Negative supply rail - must be bypassed with 0.1µF ceramic capacitor near pin to suppress ground bounce during output transitions. |
| 5 | VDD | Positive supply rail - bypassed locally with 0.1µF capacitor; supports 2.5–5.5V operation without regulator staging. |
| 6 | INA+ | Comparator A noninverting input - electrically identical to INC+ and INB+; shares same input bias current (8–80nA) and offset specs. |
| 7 | INA− | Comparator A inverting input - symmetrical to INA+; common-mode range extends to VDD − 1.1V for high-side sensing. |
| 8 | OUTA | Comparator A open-drain output - functionally identical to OUTB/OUTC/OUTD; enables wired-OR logic and level translation. |
| 9 | INB− | Comparator B inverting input - part of fully independent quad channel set; no crosstalk between channels confirmed in layout guidelines. |
| 10 | INB+ | Comparator B noninverting input - matched input characteristics ensure consistent trip points across all four comparators. |
| 11 | OUTB | Comparator B open-drain output - supports simultaneous triggering of multiple downstream logic blocks with minimal skew. |
| 12 | INC+ | Comparator C noninverting input - referenced to same VDD/VSS as other channels; no shared internal reference required. |
| 13 | INC− | Comparator C inverting input - maintains 72dB minimum CMRR across full temperature range for noisy industrial environments. |
| 14 | OUTC | Comparator C open-drain output - enables discrete threshold monitoring per channel without multiplexing overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher 1.5mA supply current per comparator, no built-in hysteresis, wider 2V–36V supply range, SO-14 package. | Suitable for high-voltage industrial controls but requires external hysteresis resistors and consumes >40× more current than MAX9034AUD+T. | Select LM339DR only when operating above +5.5V or requiring higher output sink current (>16mA); avoid for battery-critical designs. |
| TLV3704IPW | Lower 1.2μA supply current, rail-to-rail input, 350ns propagation delay, same TSSOP-14 package, RoHS-compliant. | Optimized for ultra-low-power sensor nodes but slower response limits use in >1MHz line receivers or fast photodiode pulse detection. | Choose TLV3704IPW when sub-5μA total quiescent current is mandatory and timing budget allows ≥350ns delay; MAX9034AUD+T preferred for speed-sensitive applications. |
Compared with LM339DR and TLV3704IPW, MAX9034AUD+T uniquely balances 188ns speed, 35μA efficiency, and integrated 4mV hysteresis in a standard TSSOP-14 footprint - making it optimal for portable systems needing responsive yet robust analog thresholding without design compromises.

FAQ
What is the maximum capacitive load the MAX9034AUD+T output can drive without oscillation?
The MAX9034AUD+T is characterized to drive up to 150pF without sustained oscillations, as specified in the Electrical Characteristics table. This value was verified under standard test conditions (VDD = +5V, RL = 10kΩ, CL = 15pF). For loads exceeding 150pF, external series resistance or buffer stages are recommended to maintain stability and preserve the 188ns propagation delay performance of MAX9034AUD+T.
Does the MAX9034AUD+T have a shutdown pin like the MAX9030?
No, the MAX9034AUD+T does not include a shutdown pin. Unlike the MAX9030AXT+T (which features SHDN on pin 5), the MAX9034AUD+T is a quad comparator without shutdown functionality. All four channels operate continuously when powered. The MAX9034AUD+T datasheet confirms no SHDN terminal in its pin description or functional block diagram - this feature is exclusive to the MAX9030 variant within the family.
Can the MAX9034AUD+T operate from dual supplies such as ±2.5V?
Yes, the MAX9034AUD+T supports dual-supply operation from ±1.25V to ±2.75V, as stated in the Detailed Description section. When used with dual supplies, VSS becomes the negative rail (e.g., −2.5V) and VDD the positive rail (e.g., +2.5V), maintaining the same 5V total supply range. Input common-mode range then extends from −2.5V to +1.4V (VDD − 1.1V), and rail-to-rail output swing refers to −2.5V to +2.5V. This mode is fully supported for MAX9034AUD+T.
What is the input offset voltage specification for MAX9034AUD+T over temperature?
The MAX9034AUD+T has a guaranteed input offset voltage of ±5mV maximum over the full −40°C to +125°C operating range, with a typical value of ±1mV at +25°C. Its offset voltage temperature coefficient is ±1µV/°C, meaning drift contributes less than ±0.125mV across the entire temperature span. These values are explicitly listed in the Electrical Characteristics table and apply directly to MAX9034AUD+T per its ordering information and pin configuration.
Is the MAX9034AUD+T pin-compatible with other quad comparators in TSSOP-14 packages?
The MAX9034AUD+T uses a proprietary pinout optimized for quad independent operation (e.g., pins 1/8/11/14 are outputs; pins 2/3/6/7/9/10/12/13 are inputs; pins 4/VSS and 5/VDD are shared), which differs from industry-standard arrangements like the LM339. It is not pin-compatible with LM339DR or TLV3704IPW - those devices allocate pins differently (e.g., LM339DR places all outputs on one side). Direct replacement requires PCB layout revision; MAX9034AUD+T must be used with its documented pin mapping.
