Product details
Overview
The MAX4402ASA+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 up to 400pF capacitive loads - widely deployed in automotive sensor signal conditioning and portable communications front-ends.
For engineers reviewing the MAX4402ASA+T datasheet, MAX4402ASA+T pinout, MAX4402ASA+T application, or MAX4402ASA+T equivalent, key selection criteria include its 8-pin SO package, AEC-Q100 qualification (for /V+ variants), -40°C to +125°C operating range, and absence of shutdown functionality - critical when replacing legacy dual op amps in space-constrained industrial control modules.
Technical Context
The MAX4402ASA+T implements a ground-sensing input stage enabling full common-mode voltage range from VSS to VDD − 1.4V, paired with a rail-to-rail output stage that swings within 55mV of each supply rail under 2kΩ load. Its 1MHz gain-bandwidth product and 70° phase margin ensure stable closed-loop performance at unity gain.
It operates without shutdown logic (unlike the MAX4401), uses standard dual-op-amp pinout alignment across SOT23/µMAX/SO packages, and achieves 110dB open-loop gain with 2kΩ load while maintaining 0.015% THD - making it suitable for precision DC-coupled amplification where low distortion and wide dynamic range are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V single supply - enables direct interface with Li-ion battery or 3.3V/5V logic without level-shifting. |
| Quiescent Current | 320µA per amplifier - supports always-on sensor interfaces with sub-1mW total power at 3.3V. |
| Gain-Bandwidth Product | 1MHz - sufficient for anti-aliasing filters, active RC networks, and low-frequency instrumentation amplifiers. |
| Output Drive | ±1.4mA - drives 2kΩ loads while maintaining rail-to-rail swing, supporting direct ADC input buffering. |
| Capacitive Load Stability | Up to 400pF - eliminates need for isolation resistors when driving long traces or ADC input capacitance. |
| Input Offset Voltage | ±1.0mV (typ), ±5.5mV (max) - ensures <100µV error in 100mV full-scale sensor outputs. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive and industrial motor-control environments. |
Pinout & Package
The MAX4402ASA+T is housed in an 8-pin SO (Small Outline) package (package code S8+2), with exposed pad not present, JEDEC MS-012AC compliant, thermal resistance θJA = 136°C/W on four-layer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - rail-to-rail capable, sinks/sources ±1.4mA, high-impedance in shutdown (not applicable). |
| 2 | INA− | Inverting input A - high-impedance (1000GΩ), supports ground-sensing down to VSS. |
| 3 | INA+ | Noninverting input A - matched to INA− for low offset, accepts common-mode voltages to VDD − 1.4V. |
| 4 | VSS | Negative supply - connect directly to ground in single-supply systems; defines reference for all inputs/outputs. |
| 5 | VDD | Positive supply - accepts +2.5V to +5.5V; requires 0.1µF bypass capacitor to VSS. |
| 6 | INB+ | Noninverting input B - electrically isolated from Channel A; enables independent dual-channel signal paths. |
| 7 | INB− | Inverting input B - matched to INB+, supports differential configurations without cross-talk. |
| 8 | OUTB | Amplifier B output - identical specs to OUTA; channel-to-channel isolation >100dB at 1kHz. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Swings within 55mV of VDD/VSS under 2kΩ load - preserves full dynamic range for 12-bit+ ADC interfacing. |
| Ground-sensing inputs | Common-mode range extends to VSS - enables direct amplification of 0–VREF sensor outputs without level-shifting. |
| Unity-gain stable with 400pF | No external compensation needed for typical PCB trace capacitance or ADC input capacitance - simplifies layout. |
| Low THD (0.015%) | Minimizes harmonic distortion in audio preamps and precision analog front-ends - critical for signal integrity in IR receivers. |
| AEC-Q100 qualified variant available | MAX4402AKA/V+T meets automotive stress testing - MAX4402ASA+T shares same die but lacks automotive screening. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Wider supply range (2.7V–5.5V), higher quiescent current (120µA per amp), no AEC-Q100 option, SO-8 pinout compatible. | Lacks 125°C rating and rail-to-rail output swing - unsuitable for automotive under-hood use. | Select when cost sensitivity outweighs temperature or output swing requirements. |
| MCP6022-E/SN | Lower input offset (250µV typ), higher GBW (10MHz), 1.8V–6.0V supply, SO-8 pinout, no AEC-Q100 version. | Higher bandwidth increases noise susceptibility in low-frequency sensor apps; not qualified for automotive. | Prefer for high-speed, low-offset applications where extended temperature range is not mandatory. |
Compared with LMV358IDR and MCP6022-E/SN, the MAX4402ASA+T delivers superior rail-to-rail output drive and guaranteed 125°C operation - essential for automotive and industrial designs requiring robustness over wide temperature excursions, though it trades off bandwidth and ultra-low offset.

FAQ
Does the MAX4402ASA+T include a shutdown feature?
No, the MAX4402ASA+T does not include a shutdown function. Shutdown capability is exclusive to the MAX4401 (single-channel, 6-pin SC70). The MAX4402ASA+T is a dual op amp without SHDN pin or related circuitry - confirmed by pin configuration diagrams and electrical specifications tables in the official datasheet. This simplifies biasing but means power must be managed externally if low-quiescent states are required.
What is the maximum capacitive load the MAX4402ASA+T can drive without oscillation?
The MAX4402ASA+T is unity-gain stable with capacitive loads up to 400pF, as verified in the Electrical Characteristics table and Typical Operating Characteristics (Figure MAX4400 toc19). This specification applies across the full -40°C to +125°C temperature range and eliminates the need for series isolation resistors when driving ADC inputs or long PCB traces - a key advantage over many general-purpose op amps requiring external compensation.
Is the MAX4402ASA+T AEC-Q100 qualified?
The MAX4402ASA+T itself is not AEC-Q100 qualified. Only specific variants - namely MAX4402AKA/V+T and MAX4402AUA/V+T - carry AEC-Q100 qualification. The MAX4402ASA+T uses the same silicon die and SO package but lacks the automotive-grade screening and test documentation. For automotive applications requiring formal qualification, the /V+T variants must be selected instead.
What is the input common-mode voltage range of the MAX4402ASA+T?
The MAX4402ASA+T features ground-sensing inputs with a common-mode voltage range from VSS to VDD − 1.4V (minimum) at +25°C, extending to VDD − 1.5V over temperature. This allows direct amplification of signals referenced to ground - such as thermistor or bridge sensor outputs - without level-shifting circuitry, significantly reducing component count in precision measurement systems.
Can the MAX4402ASA+T operate from a 2.5V supply?
Yes, the MAX4402ASA+T is fully specified to operate from a +2.5V single supply, as stated in the Absolute Maximum Ratings and Electrical Characteristics sections. At 2.5V, it maintains rail-to-rail output swing, 320µA quiescent current per amplifier, and 1MHz gain-bandwidth product - enabling compatibility with modern ultra-low-voltage microcontrollers and battery-powered IoT sensors where supply headroom is constrained.
