Product details

Overview

MAX4402AUA/V+T from Maxim Integrated is a dual, rail-to-rail output operational amplifier optimized for automotive applications, operating from a single +2.5V to +5.5V supply, drawing 320µA per amplifier, delivering ±1.4mA output current, and specified over –40°C to +125°C with AEC-Q100 qualification.

For engineers reviewing the MAX4402AUA/V+T datasheet, MAX4402AUA/V+T pinout, MAX4402AUA/V+T application, or MAX4402AUA/V+T equivalent, key selection criteria include its 1MHz gain-bandwidth product, 400pF capacitive-load stability, ground-sensing inputs, 110dB open-loop gain at 2kΩ load, and automotive-grade reliability in the 8-pin µMAX package.

Technical Context

The MAX4402AUA/V+T integrates two independent high-precision op amps in a single monolithic die, each featuring rail-to-rail output swing within 55mV of VDD and 30mV of VSS at 2kΩ load, unity-gain stable up to 400pF, and ground-sensing input common-mode range extending to VSS.

It employs a low-noise, low-power CMOS input stage with 1000GΩ input resistance, 1pA typical input bias current, and 36nV/√Hz input voltage noise density at 10kHz - enabling accurate sensor signal conditioning in space-constrained automotive modules.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	+2.5V to +5.5V single supply - supports direct interface with 3.3V and 5V microcontrollers and sensors without level-shifting.
Quiescent Current per Amplifier	320µA at 2.5V - enables always-on operation in battery-sensitive automotive subsystems (e.g., door modules, seat controls).
Gain-Bandwidth Product	1MHz - sufficient for DC–100kHz signal conditioning in infrared receivers, ignition timing circuits, and sensor front-ends.
Capacitive-Load Stability	Stable up to 400pF - eliminates need for external isolation resistors when driving long PCB traces or EMI filters.
Input Offset Voltage	±1.0mV (typ), ±5.5mV (max) - ensures <100µV error in 100mV full-scale sensor outputs (e.g., thermistor bridges, Hall-effect sensors).
Open-Loop Gain	110dB at 2kΩ load - provides >100,000× closed-loop accuracy for precision zero-crossing detection and active filtering.
Operating Temperature	–40°C to +125°C - validated for under-hood and cabin-mounted automotive electronics per AEC-Q100 Grade 1.

Pinout & Package

MAX4402AUA/V+T 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	INA−	Inverting input of amplifier A - accepts differential or single-ended feedback configurations; ground-sensing down to VSS.
2	INA+	Noninverting input of amplifier A - high-impedance CMOS node (1000GΩ); minimal loading on high-Z sensors.
3	VSS	Negative supply terminal - must be connected to system ground in single-supply operation; reference for all input/output voltages.
4	OUTA	Output of amplifier A - rail-to-rail swing (within 55mV of VDD, 30mV of VSS at 2kΩ); drives capacitive loads ≤400pF directly.
5	OUTB	Output of amplifier B - electrically isolated from OUTA; channel-to-channel isolation ≥70dB at 100kHz supports dual-path signal processing.
6	INB−	Inverting input of amplifier B - independent of INA−; enables dual-channel instrumentation or differential pair amplification.
7	INB+	Noninverting input of amplifier B - matched offset and bias performance to INA+/INA− for consistent dual-channel behavior.
8	VDD	Positive supply terminal - bypass with 0.1µF ceramic capacitor to VSS for stable operation across temperature and supply ripple.

Key Features

Feature	Design Value
AEC-Q100 Qualified	Validated for automotive use (Grade 1, –40°C to +125°C), including HTOL, TC, and ESD testing - meets OEM requirements for powertrain and body electronics.
Rail-to-Rail Output	Swings to within 55mV of VDD and 30mV of VSS at 2kΩ load - maximizes dynamic range in 3.3V systems, eliminating need for negative supply in sensor interfaces.
Ground-Sensing Inputs	Input common-mode range extends to VSS - enables direct connection of single-ended transducers (e.g., thermocouples, RTDs) referenced to system ground.
Unity-Gain Stable to 400pF	No external compensation required when driving long traces, EMI filters, or ADC input capacitance - reduces BOM count and layout complexity.
Low Input Bias Current	±0.1pA typical - prevents signal degradation in high-impedance pH electrodes, photodiode transimpedance stages, and piezoelectric sensor buffers.
110dB Open-Loop Gain	Ensures <0.01% gain error in 100× closed-loop configurations - critical for precision current sensing and active filter Q-factor control.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual op amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TSV912IDT	Higher 8MHz GBW but higher 1.1mA quiescent current; not AEC-Q100 qualified; 1.1mV VOS (max)	Better for wideband audio or fast control loops; unsuitable for automotive production due to missing qualification and higher power draw	Select only for non-automotive industrial designs requiring higher speed and where 3.5× higher supply current is acceptable.
MCP6022-E/SN	Lower 10µV VOS (typ), but only rated to +85°C; 1MHz GBW same; 1mA quiescent current; no AEC-Q100 certification	Preferred for precision lab instruments or consumer devices needing ultra-low offset; fails automotive thermal and reliability requirements	Use only in commercial-grade applications where extended temperature operation and automotive qualification are not required.

Compared with TSV912IDT and MCP6022-E/SN, MAX4402AUA/V+T uniquely combines AEC-Q100 Grade 1 qualification, 125°C operation, 320µA ultra-low quiescent current, and rail-to-rail output in a space-saving µMAX package - making it the sole fit for cost-sensitive, thermally demanding automotive signal conditioning.

FAQ

What is the maximum capacitive load the MAX4402AUA/V+T can drive without external compensation?

The MAX4402AUA/V+T is unity-gain stable up to 400pF, as confirmed in the Electrical Characteristics table and Typical Operating Characteristics section. This means it can directly drive ADC input capacitance, long PCB traces, or EMI filter capacitors ≤400pF without requiring series isolation resistors or external compensation networks - simplifying layout and reducing component count in automotive sensor interfaces.

Is the MAX4402AUA/V+T pin-compatible with other variants in the MAX4400–MAX4403 family?

No, the MAX4402AUA/V+T uses an 8-pin µMAX package (U8+1), while the MAX4402AKA/V+T uses an 8-pin SOT23 (K8+5A) and the MAX4402ASA+ uses an 8-pin SO (S8+2). Pin numbering and physical dimensions differ across these packages - board redesign is required when substituting between them. Always verify land pattern compatibility using Maxim's official footprint data (Land Pattern Number 90-0092).

Does the MAX4402AUA/V+T include a shutdown feature like the MAX4401?

No, the MAX4402AUA/V+T does not include a shutdown function. Shutdown mode is exclusive to the single-amplifier MAX4401 (6-pin SC70), as explicitly stated in the Selector Guide and Pin Description sections. The MAX4402AUA/V+T contains two independent amplifiers with no SHDN pin - power control must be implemented externally via VDD switching if needed.

What is the input common-mode voltage range for the MAX4402AUA/V+T?

The input common-mode voltage range for the MAX4402AUA/V+T extends from VSS to (VDD – 1.4V) at +25°C and VSS to (VDD – 1.5V) over the full –40°C to +125°C range, as specified in the Electrical Characteristics tables. This ground-sensing capability allows direct interfacing with sensors referenced to system ground - such as thermistors, strain gauges, and current-sense shunts - without level-shifting circuitry.

How does the AEC-Q100 qualification of the MAX4402AUA/V+T impact its use in automotive designs?

The /V+ suffix in MAX4402AUA/V+T denotes AEC-Q100 qualification (Grade 1), meaning it has passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and ESD robustness per automotive standards. This qualification validates its suitability for under-hood and cabin-mounted applications - enabling direct use in production automotive ECUs without additional qualification effort by Tier 1 suppliers or OEMs.
