Product details
Overview
MAX4402AUA from Maxim Integrated is a dual, rail-to-rail output operational amplifier optimized for single-supply operation from +2.5V to +5.5V, drawing 320µA per amplifier, delivering ±1.4mA output current, and featuring unity-gain stability with up to 400pF capacitive load-used in automotive sensor signal conditioning and portable instrumentation.
For engineers reviewing the MAX4402AUA datasheet, MAX4402AUA pinout, MAX4402AUA application, or MAX4402AUA equivalent, this page delivers verified package mapping (8-pin µMAX), AEC-Q100 qualification status, rail-to-rail output swing within 55mV of rails at 2kΩ, input offset voltage ≤±5.5mV over temperature, and ground-sensing inputs for low-side sensing in battery-powered systems.
Technical Context
The MAX4402AUA implements a CMOS input stage with ground-sensing capability and a rail-to-rail complementary output stage, enabling full dynamic range utilization in single-supply configurations. Its 1MHz gain-bandwidth product and 70° phase margin ensure stable unity-gain operation with capacitive loads up to 400pF without external compensation.
It operates across –40°C to +125°C with guaranteed performance including 65dB minimum CMRR over full temperature range, 74dB PSRR, and 85dB large-signal voltage gain into 2kΩ-making it suitable for harsh-environment analog front-ends where supply headroom and thermal robustness are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V - supports direct connection to Li-ion battery (3.0–4.2V) or regulated 3.3V/5V rails without level-shifting. |
| Quiescent Current per Amplifier | 320µA (typ at 2.5V) - enables always-on sensor amplification in power-constrained automotive modules. |
| Rail-to-Rail Output Swing | Within 55mV of VDD/VSS at 2kΩ load - preserves >98% of available signal swing for ADC interfacing. |
| Input Offset Voltage | ±1.0mV (typ), ±5.5mV (max over –40°C to +125°C) - ensures <0.3% error in 12-bit precision current-sense applications. |
| Gain-Bandwidth Product | 1MHz - sufficient for anti-aliasing filtering, zero-crossing detection, and closed-loop control up to ~100kHz. |
| Capacitive-Load Stability | Stable with CL ≤ 400pF - eliminates need for isolation resistors when driving ADC input capacitance or long PCB traces. |
| Common-Mode Input Range | VSS to VDD – 1.5V - enables ground-referenced signal acquisition (e.g., shunt-based current sensing). |
Pinout & Package
MAX4402AUA is housed in an 8-pin µMAX package (package code U8+1), measuring 3mm × 3mm × 1.1mm, with exposed pad for thermal enhancement and RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Amplifier A output | Low-impedance rail-to-rail source/sink node; drives 2kΩ load to within 55mV of supply rails. |
| 2 (INA+) | Amplifier A noninverting input | CMOS input with ±100pA bias current; accepts signals down to VSS (ground-sensing). |
| 3 (INA−) | Amplifier A inverting input | Differential pair input; matched to INA+ for <±5.5mV offset over full temperature range. |
| 4 (VDD) | Positive supply | Accepts +2.5V to +5.5V; requires local 0.1µF bypass capacitor to minimize supply noise coupling. |
| 5 (VSS) | Negative supply / ground | Reference node for single-supply operation; must be connected directly to system ground plane. |
| 6 (INB−) | Amplifier B inverting input | Independent high-impedance input; electrically isolated from INA− with >100dB channel-to-channel isolation at 10kHz. |
| 7 (INB+) | Amplifier B noninverting input | Matches INA+ characteristics; enables dual-channel differential sensing without cross-talk. |
| 8 (OUTB) | Amplifier B output | Functionally identical to OUTA; supports independent gain stages or parallel drive for higher output current. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers full-scale swing to within 55mV of VDD/VSS at 2kΩ, maximizing dynamic range for 12-bit+ ADCs. |
| Ground-sensing inputs | Common-mode range extends to VSS, enabling accurate amplification of shunt voltages referenced to system ground. |
| AEC-Q100 qualified | Qualified per AEC-Q100 Rev G Grade 0 (–40°C to +125°C), certified for automotive powertrain and body electronics. |
| Unity-gain stable with 400pF load | Eliminates need for external output series resistor when driving typical ADC input capacitance (10–20pF) or long traces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Higher quiescent current (120µA per amp vs. 320µA), lower GBW (1MHz same), no AEC-Q100 qualification. | Targeted at commercial-grade industrial controls, not automotive. | Prefer MAX4402AUA for AEC-Q100 compliance and ground-sensing inputs in automotive designs. |
| MCP6022-E/SN | Lower input offset (±250µV typ), wider supply range (2.7V–5.5V), but only rated to +85°C (not +125°C). | Suitable for consumer and medical devices, not under-hood automotive use. | Choose MAX4402AUA when operating above +85°C or requiring guaranteed performance to +125°C. |
Compared with LMV358IDR and MCP6022-E/SN, the MAX4402AUA uniquely combines AEC-Q100 Grade 0 qualification, ground-sensing inputs, and guaranteed –40°C to +125°C operation-making it the only option among the three qualified for automotive powertrain signal conditioning.

FAQ
Is MAX4402AUA AEC-Q100 qualified?
Yes, MAX4402AUA/V+T is AEC-Q100 qualified per Grade 0 (–40°C to +125°C), as explicitly stated in the Benefits and Features section of the official datasheet. This qualification applies only to variants marked "/V+", including MAX4402AUA/V+T. The standard MAX4402AUA (without /V+) is not AEC-Q100 qualified.
What is the package type and footprint for MAX4402AUA?
MAX4402AUA uses the 8-pin µMAX package (outline number 21-0036, land pattern 90-0092), a 3mm × 3mm exposed-pad package with gull-wing leads. It is distinct from SOT23-8 and SO-8 packages used by other MAX4402 variants-correct PCB layout requires the µMAX-specific footprint.
Does MAX4402AUA include a shutdown feature?
No, MAX4402AUA does not include a shutdown feature. Shutdown is exclusive to the MAX4401 (single-channel, 6-pin SC70). The MAX4402 family-including MAX4402AUA-is a dual op amp without SHDN pin or low-power disable functionality.
What is the maximum capacitive load the MAX4402AUA can drive stably?
MAX4402AUA is unity-gain stable with capacitive loads up to 400pF, as confirmed in the Electrical Characteristics table and Applications Information section. This allows direct connection to typical ADC input capacitances and PCB trace capacitances without external isolation resistors.
Can MAX4402AUA operate from a 2.5V supply?
Yes, MAX4402AUA operates from a minimum supply voltage of +2.5V (absolute maximum ratings and Electrical Characteristics confirm VDD = 2.5V operation). At 2.5V, quiescent current is 320µA per amplifier, and rail-to-rail output swing remains functional-enabling compatibility with single-cell Li-ion and low-voltage logic systems.
