Product details
Overview
The MAX4480AUK-T from Maxim Integrated is a single-channel, rail-to-rail output operational amplifier optimized for low-power, single-supply operation across -40°C to +125°C. It draws only 50µA quiescent current, operates from +2.5V to +5.5V, delivers 3.0mA output drive, and maintains unity-gain stability with up to 400pF capacitive load-ideal for sensor signal conditioning in automotive electronic ignition modules.
For engineers reviewing the MAX4480AUK-T datasheet, MAX4480AUK-T pinout, MAX4480AUK-T application, or MAX4480AUK-T equivalent, key selection criteria include its SC70-5 package footprint, 105dB large-signal voltage gain, 0.005% THD at 100kΩ load, rail-to-rail output swing within 80mV of rails, and guaranteed operation over extended automotive temperature range.
Technical Context
This op amp employs a BiCMOS process to achieve ultra-low quiescent current while preserving rail-to-rail output stage performance. Its input common-mode range extends from VSS to VDD − 1.3V, and it features 1000MΩ input resistance with ±100pA max input bias current.
The device achieves 140kHz gain-bandwidth product and 80V/ms slew rate under 5kΩ load, enabling stable amplification of low-frequency sensor signals without phase reversal or oscillation-even when driving moderate capacitive loads typical of PCB traces and filtering networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V - supports direct connection to Li-ion battery or 3.3V/5V system rails without regulation. |
| Quiescent Current | 50µA per amplifier - enables multi-year battery life in portable infrared receivers and handheld instruments. |
| Rail-to-Rail Output Swing | VSS + 0.02V to VDD − 0.03V (RL = 5kΩ) - maximizes dynamic range in single-supply data acquisition systems. |
| Large-Signal Voltage Gain | 105dB with 5kΩ load - ensures < 0.001% gain error in precision zero-crossing detectors. |
| Total Harmonic Distortion | 0.005% at 10kHz, 2Vp-p, RL = 100kΩ - preserves fidelity in analog front-ends for sensor signal detection. |
| Capacitive-Load Stability | Stable up to 400pF - eliminates need for external isolation resistors in EMI-filtered sensor interfaces. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive applications including electronic ignition modules. |
Pinout & Package
The MAX4480AUK-T is housed in a 5-pin SC70 package (outline 21-0076), measuring 2.0mm × 1.25mm × 0.95mm, with moisture sensitivity level MSL1 and RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN+ | Noninverting Input | High-impedance node (1000MΩ) accepting DC-coupled sensor signals up to VDD − 1.3V. |
| 2 - IN− | Inverting Input | Differential input terminal; matched to IN+ for < 5.5mV offset and < 100pA input offset current. |
| 3 - OUT | Amplifier Output | Rail-to-rail stage capable of sourcing/sinking 3.0mA into 5kΩ load while maintaining linearity. |
| 4 - VSS | Negative Supply / Ground | Reference for single-supply operation; requires 0.01µF bypass capacitor to minimize noise coupling. |
| 5 - VDD | Positive Supply | Accepts +2.5V to +5.5V; must be bypassed with 0.1µF capacitor to ground for stability. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel, low-power, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4470ASA+ | Same SC70-5 package, but 1.8V–5.5V supply range and 1.2MHz GBW; higher quiescent current (120µA). | Better suited for higher-speed sensor interfaces requiring >100kHz bandwidth. | Select MAX4470ASA+ only if wider supply range or higher bandwidth is required; MAX4480AUK-T offers lower power and better THD. |
| TSV911ICT | SC70-5, 2.5V–5.5V, 40µA IQ, but only specified to +105°C and lacks 400pF capacitive-load guarantee. | Applicable in commercial-grade portable instruments but not automotive under-hood use. | Choose TSV911ICT for cost-sensitive consumer designs; MAX4480AUK-T remains preferred for AEC-Q100-compliant systems. |
Compared with MAX4470ASA+ and TSV911ICT, the MAX4480AUK-T uniquely combines automotive temperature rating, 400pF capacitive-load stability, and 50µA quiescent current in SC70-5-making it the only option qualified for harsh-environment zero-crossing detection without performance trade-offs.

FAQ
What is the maximum capacitive load the MAX4480AUK-T can drive while remaining stable?
The MAX4480AUK-T is unity-gain stable with capacitive loads up to 400pF, as confirmed in the Electrical Characteristics table and Typical Operating Characteristics (Figure MAX4480 toc19). This allows direct connection to PCB traces, RC filters, or ESD protection networks without external isolation resistors-critical for maintaining signal integrity in automotive sensor interfaces where layout constraints limit component placement.
Does the MAX4480AUK-T have a shutdown pin?
No, the MAX4480AUK-T does not include a shutdown function. Shutdown capability is exclusive to the MAX4481 variant (6-pin SC70/SOT23), which adds SHDN pin and reduces supply current to 0.5µA max in shutdown mode. The MAX4480AUK-T is a single-amplifier device in 5-pin SC70 with no dedicated enable/disable control-its operation is always active when powered within the +2.5V to +5.5V supply range.
What is the input common-mode voltage range for the MAX4480AUK-T?
The input common-mode voltage range for the MAX4480AUK-T is specified as VSS to VDD − 1.3V at +25°C, and VSS to VDD − 1.4V over the full −40°C to +125°C range. This allows the device to accept signals near ground in single-supply configurations while rejecting common-mode noise-essential for accurate amplification of low-level sensor outputs in automotive and industrial applications.
Can the MAX4480AUK-T operate from a 2.5V supply?
Yes, the MAX4480AUK-T is fully specified to operate from a minimum supply voltage of +2.5V, with all key parameters-including rail-to-rail output swing, 105dB gain, and 0.005% THD-guaranteed across the entire −40°C to +125°C temperature range at this voltage. This enables direct integration into 2.5V logic domains and battery-powered systems where voltage headroom is constrained.
What package type is used for the MAX4480AUK-T?
The MAX4480AUK-T uses a 5-pin SC70 package (package code X5+1, outline 21-0076), measuring 2.0mm × 1.25mm × 0.95mm. This ultra-small outline matches the footprint of SOT23-5 but offers improved thermal performance and is RoHS-compliant with lead-free terminations-making it suitable for high-density automotive PCB layouts where space and reliability are critical.
