Product details
Overview
The MAX4402AUA-T from Maxim Integrated is a dual, rail-to-rail output operational amplifier optimized for single-supply operation from +2.5V to +5.5V, drawing only 320µA per amplifier, delivering ±1.4mA output current, and featuring unity-gain stability with capacitive loads up to 400pF - widely deployed in automotive sensor signal conditioning and portable communications front-ends.
For engineers reviewing the MAX4402AUA-T datasheet, MAX4402AUA-T pinout, MAX4402AUA-T application, or MAX4402AUA-T equivalent, key selection criteria include its AEC-Q100 qualification (for /V+ variants), 8-pin µMAX package footprint, 1MHz gain-bandwidth product, ground-sensing inputs, and guaranteed operation from –40°C to +125°C in harsh environments.
Technical Context
The MAX4402AUA-T implements a CMOS input stage with ground-sensing capability and a rail-to-rail output stage capable of swinging within 55mV of VDD and 30mV of VSS into a 2kΩ load. Its internal compensation ensures unity-gain stability without external components when driving up to 400pF.
It operates across the full automotive temperature range (–40°C to +125°C) and meets AEC-Q100 stress-test requirements for reliability-critical applications. The device lacks shutdown functionality - distinguishing it from the MAX4401 - and is specified with input offset voltage ≤ ±5.5mV and PSRR ≥ 74dB over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V - enables direct interfacing with Li-ion battery systems and 3.3V/5V logic without level-shifting. |
| Quiescent Current per Amplifier | 320µA at 2.5V - supports ultra-low-power sensor amplification in always-on automotive modules. |
| Gain-Bandwidth Product | 800kHz - sufficient for DC–200kHz signal conditioning in infrared receivers and ignition timing circuits. |
| Rail-to-Rail Output Swing | Within 55mV of VDD and 30mV of VSS into 2kΩ - maximizes dynamic range in single-supply data acquisition paths. |
| Capacitive-Load Stability | Stable up to 400pF - eliminates need for isolation resistors when driving ADC input capacitance or long PCB traces. |
| Input Offset Voltage (max) | ±5.5mV at +125°C - ensures <1% error in 1V full-scale sensor outputs without trimming. |
| Operating Temperature Range | –40°C to +125°C - qualified for under-hood automotive locations and industrial motor control feedback loops. |
Pinout & Package
The MAX4402AUA-T is housed in an 8-pin µMAX package (package code U8+1), measuring 3mm × 3mm × 1.1mm with exposed pad thermal enhancement. This RoHS-compliant, lead(Pb)-free package provides low θJA = 206.3°C/W on a four-layer board for reliable thermal performance in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives downstream circuitry with rail-to-rail swing and ±1.4mA sourcing/sinking capability. |
| 2 | INA+ | Noninverting input A - high-impedance (1000GΩ), ground-sensing node compatible with single-ended sensor outputs. |
| 3 | INA− | Inverting input A - matched to INA+ for precision differential gain configurations. |
| 4 | VDD | Positive supply - accepts +2.5V to +5.5V; requires local 0.1µF bypass capacitor to ground for noise immunity. |
| 5 | VSS | Negative supply - connected to ground in single-supply operation; serves as reference for ground-sensing inputs. |
| 6 | INB− | Inverting input B - electrically isolated from Channel A; channel-to-channel isolation >100dB at 10kHz. |
| 7 | INB+ | Noninverting input B - independent high-impedance node for second sensor or signal path. |
| 8 | OUTB | Amplifier B output - fully independent channel with identical AC/DC specs to OUTA; no shared biasing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers full supply-voltage utilization - critical for maximizing SNR in 12-bit ADC interfaces with 3.3V supplies. |
| Ground-sensing inputs | Accepts common-mode voltages down to VSS (0V), enabling direct connection to thermistors, RTDs, or bridge sensors referenced to ground. |
| Unity-gain stable to 400pF | Eliminates need for output series resistors when driving typical ADC input capacitance (10–20pF) plus PCB trace capacitance. |
| AEC-Q100 qualified (MAX4402AUA/V+T) | Validated for automotive use including temperature cycling, HAST, and ESD testing - required for engine control and body electronics. |
| Low THD (0.015%) at 2kΩ | Preserves signal fidelity in audio preamps and analog sensor chains where harmonic distortion must remain below audible thresholds. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Higher quiescent current (150µA per amp vs. 320µA), lower GBW (1MHz), no AEC-Q100 qualification, SO-8 only. | Targeted at commercial-grade industrial controls, not automotive under-hood use. | Select when cost sensitivity outweighs automotive qualification and ultra-low power is unnecessary. |
| MCP6022-E/SN | Lower input offset (±250µV typ), higher supply current (1mA), wider supply range (2.7V–6.0V), no AEC-Q100 rating. | Suitable for precision instrumentation but unqualified for automotive temperature and reliability stress tests. | Prefer for high-accuracy sensor nodes where offset drift matters more than temperature range or qualification. |
Compared with LMV358IDR and MCP6022-E/SN, the MAX4402AUA-T uniquely combines AEC-Q100 qualification, 125°C operation, rail-to-rail output, and sub-400µA quiescent current - making it the only choice for dual-channel signal conditioning in automotive powertrain and chassis modules requiring both reliability and efficiency.

FAQ
What is the operating temperature range of the MAX4402AUA-T?
The MAX4402AUA-T is specified for continuous operation from –40°C to +125°C. This full automotive temperature range is guaranteed across all electrical parameters in the datasheet, and the /V+ variant (MAX4402AUA/V+T) carries formal AEC-Q100 qualification for use in engine control, transmission, and body electronics modules.
Does the MAX4402AUA-T include a shutdown feature?
No, the MAX4402AUA-T does not include a shutdown feature. Shutdown functionality is exclusive to the MAX4401 (single-channel, 6-pin SC70). The MAX4402AUA-T is a dual op amp without SHDN pin or related control logic - confirmed by its 8-pin µMAX pinout and absence of shutdown-related specifications in its electrical characteristics table.
What package type is used for the MAX4402AUA-T?
The MAX4402AUA-T uses the 8-pin µMAX package (outline number 21-0036, land pattern 90-0092), a 3mm × 3mm surface-mount package with exposed thermal pad. It is RoHS-compliant and marked with "+" indicating lead(Pb)-free construction. This package offers superior thermal performance (θJA = 206.3°C/W on four-layer board) versus SOT23 alternatives.
Is the MAX4402AUA-T AEC-Q100 qualified?
The MAX4402AUA-T itself is not AEC-Q100 qualified; qualification applies only to the automotive-grade variant MAX4402AUA/V+T. The "/V+" suffix denotes full AEC-Q100 compliance including temperature cycling, humidity testing, and ESD validation. Standard MAX4402AUA-T parts meet the same electrical specs but lack formal automotive stress-test documentation.
What is the maximum capacitive load the MAX4402AUA-T can drive while remaining stable?
The MAX4402AUA-T is unity-gain stable with capacitive loads up to 400pF, as verified in the datasheet's Electrical Characteristics table and Typical Operating Characteristics (Figure MAX4400 toc19). This allows direct connection to ADC inputs, long PCB traces, or RC filters without external isolation resistors - a key advantage over many general-purpose op amps.
