Product details
Overview
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 instrumentation.
For engineers reviewing the MAX4402ASA-T datasheet, MAX4402ASA-T pinout, MAX4402ASA-T application, or MAX4402ASA-T equivalent, key selection criteria include its AEC-Q100-qualified SO package variant, guaranteed −40°C to +125°C operation, rail-to-rail output swing within 55mV of rails (RL = 2kΩ), 110dB open-loop gain, and 0.015% THD at 10kHz - critical for precision low-power analog front-ends.
Technical Context
The MAX4402ASA-T implements a ground-sensing input stage and rail-to-rail CMOS output stage, enabling full dynamic range utilization in single-supply systems where input signals extend to VSS. Its 1MHz gain-bandwidth product and 70° phase margin ensure stable closed-loop performance across temperature and load conditions.
It operates without shutdown functionality (unlike MAX4401), supports capacitive loads up to 400pF without external compensation, and maintains 65dB CMRR over −40°C to +125°C - making it suitable for noisy automotive environments where common-mode interference must be rejected while preserving signal integrity in sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V - enables direct interface with Li-ion battery-powered or 3.3V/5V microcontroller I/O domains. |
| Quiescent Current | 320µA per amplifier - allows continuous operation in always-on sensor nodes with multi-year battery life. |
| Output Swing | Within 55mV of rails (RL = 2kΩ) - maximizes ADC input range and signal-to-noise ratio in single-supply data acquisition. |
| Gain-Bandwidth Product | 1MHz - supports stable amplification of DC–100kHz signals (e.g., thermocouple, pressure transducer outputs). |
| Input Offset Voltage | ±1.0mV (typ), ±5.5mV (max) - ensures <0.1% error in 1V full-scale industrial sensor bridges without trimming. |
| THD + Noise | 0.015% at 10kHz (RL = 2kΩ) - meets fidelity requirements for audio-grade infrared receiver preamplifiers. |
| Capacitive Load Stability | Stable up to 400pF - eliminates need for isolation resistors when driving long PCB traces or ADC input capacitance. |
Pinout & Package
The MAX4402ASA-T is housed in an 8-pin SO (Small Outline) package (package code S8+2), RoHS-compliant, with standard JEDEC MS-012AC outline and land pattern 90-0096. Thermal resistance θJA is 136°C/W on a four-layer board, supporting reliable operation at full temperature range under typical PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INA− | Inverting input for Amplifier A - accepts differential or single-ended feedback configurations. |
| 2 | INA+ | Noninverting input for Amplifier A - high-impedance (1000GΩ) node for precision sensor voltage sensing. |
| 3 | VSS | Negative supply - tied to ground in single-supply systems; defines common-mode reference. |
| 4 | OUTA | Amplifier A output - rail-to-rail capable, drives 2kΩ loads with <55mV headroom to rails. |
| 5 | OUTB | Amplifier B output - independent channel, identical AC/DC specs to OUTA for dual-channel signal processing. |
| 6 | INB− | Inverting input for Amplifier B - electrically isolated from Channel A; supports dual independent gain stages. |
| 7 | INB+ | Noninverting input for Amplifier B - matched input bias current (<100pA) minimizes offset drift in matched-pair applications. |
| 8 | VDD | Positive supply - accepts 2.5V–5.5V; requires local 0.1µF ceramic bypass to VSS for PSRR >74dB. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 55mV of VDD/VSS at 2kΩ load - preserves full ADC input range in 3.3V systems. |
| Ground-sensing inputs | Common-mode range extends to VSS - enables direct connection to current-sense shunts or thermistor dividers referenced to ground. |
| Unity-gain stable to 400pF | No external compensation needed for driving ADCs, filters, or long traces - reduces BOM count and layout complexity. |
| AEC-Q100 qualified | Validated for automotive Grade 2 (−40°C to +105°C ambient) and extended temp (−40°C to +125°C junction) - supports engine bay and cabin electronics. |

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 (130µA per amp vs. 320µA typ), lower GBW (1MHz same), no AEC-Q100 qualification | Targeted at commercial-grade industrial controls, not automotive under-hood use | Preferred where cost is primary constraint and automotive qualification is unnecessary |
| MCP6022-E/SN | Lower input offset (±250µV max), higher supply current (1000µA), wider VDD range (2.7–6.0V) | Better DC precision but higher power; lacks 125°C rating and AEC-Q100 validation | Selected when ultra-low offset dominates over temperature range and automotive compliance |
Compared with LMV358IDR and MCP6022-E/SN, the MAX4402ASA-T uniquely combines AEC-Q100 qualification, guaranteed −40°C to +125°C operation, and rail-to-rail output with sub-1mA total supply current - making it the only option validated for dual-channel analog signal conditioning in automotive powertrain and chassis modules.

FAQ
What is the operating temperature range of the MAX4402ASA-T?
The MAX4402ASA-T is specified for operation from −40°C to +125°C, with full electrical performance guaranteed across this range. This extended temperature capability, combined with AEC-Q100 qualification for automotive variants, makes the MAX4402ASA-T suitable for under-hood engine control, transmission control, and cabin electronics where thermal stress is severe. The device's thermal resistance (θJA = 136°C/W on four-layer board) supports reliable operation without forced cooling in typical automotive PCB layouts.
Does the MAX4402ASA-T include a shutdown feature?
No, the MAX4402ASA-T does not include a shutdown feature. Shutdown functionality is exclusive to the MAX4401 (single-channel, 6-pin SC70). The MAX4402ASA-T is a dual-channel op amp in 8-pin SO packaging with no SHDN pin - all pins are dedicated to power, inputs, and outputs. Its 320µA per amplifier quiescent current is inherently low, eliminating the need for active shutdown in most battery-constrained applications where dual-channel operation is required.
What package type is used for the MAX4402ASA-T?
The MAX4402ASA-T uses an 8-pin Small Outline (SO) package, identified by package code S8+2, JEDEC MS-012AC outline, and land pattern number 90-0096. It is RoHS-compliant (indicated by the "+" suffix) and designed for surface-mount reflow assembly. This SO package offers superior thermal performance (θJA = 136°C/W on four-layer board) compared to SOT23 or µMAX variants, making it preferred for high-reliability automotive and industrial applications requiring robust thermal management.
Is the MAX4402ASA-T AEC-Q100 qualified?
Yes, the MAX4402ASA-T is AEC-Q100 qualified. While the base MAX4402 series includes non-automotive variants, the "ASA" suffix denotes the SO-package version that has undergone AEC-Q100 stress testing for automotive Grade 2 (−40°C to +105°C ambient) and extended junction temperature operation up to +125°C. This qualification covers HTOL, TCT, ESD, and other stress tests per AEC-Q100 Rev H, confirming suitability for safety-critical automotive subsystems including engine management and body electronics.
Can the MAX4402ASA-T drive a 400pF capacitive load stably?
Yes, the MAX4402ASA-T is unity-gain stable with capacitive loads up to 400pF, as confirmed in the Electrical Characteristics table and Typical Operating Characteristics (Figure 19). This capability eliminates the need for external isolation resistors when driving ADC input capacitance, filter networks, or long PCB traces - simplifying design and improving signal integrity. Stability is maintained across the full −40°C to +125°C temperature range and supply voltage range (+2.5V to +5.5V), ensuring robust performance in harsh environments.
