Product details
Overview
MAX4480AXK-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 ±3mA output drive, and maintains unity-gain stability with up to 400pF capacitive load - ideal for automotive sensor signal conditioning and portable infrared receivers.
For engineers reviewing the MAX4480AXK-T datasheet, MAX4480AXK-T pinout, MAX4480AXK-T application, or MAX4480AXK-T equivalent, key selection criteria include its SC70-5 package footprint, 105dB open-loop gain at 5kΩ load, 0.005% THD with 100kΩ load, and guaranteed operation over extended temperature range without external compensation.
Technical Context
The MAX4480AXK-T uses a BiCMOS process to achieve rail-to-rail output swing within 80mV of VSS and VDD while sustaining 3.0mA sink/source capability. Its input stage supports common-mode voltage from VSS to (VDD − 1.3V), enabling direct interfacing with single-supply sensors and ADCs.
It features unity-gain stability up to 400pF capacitive load without external compensation and exhibits 140kHz gain-bandwidth product with 70° phase margin. Shutdown functionality is absent - unlike the MAX4481 - confirming it as a dedicated low-quiescent-current amplifier without enable control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V - enables direct use with Li-ion, 3.3V, and 5V systems without level-shifting. |
| Quiescent Current | 50µA per amplifier - allows battery-powered operation for >1 year in always-on sensor nodes. |
| Rail-to-Rail Output Swing | VSS + 0.02V to VDD − 0.03V at RL = 5kΩ - maximizes dynamic range in single-supply data acquisition. |
| Large-Signal Voltage Gain | 105dB at RL = 5kΩ - ensures <10µV error contribution in precision DC-coupled amplification. |
| Capacitive-Load Stability | Stable up to 400pF - eliminates need for isolation resistors when driving ADC inputs or long traces. |
| Input Offset Voltage | ±1mV (max) - supports accurate zero-crossing detection and low-level signal amplification. |
| THD + Noise | 0.005% at 10kHz, RL = 100kΩ - meets audio-grade distortion requirements in IR receiver front-ends. |
Pinout & Package
MAX4480AXK-T is housed in a 5-pin SC70 package (outline 21-0076), measuring 2.0mm × 1.25mm × 0.95mm, with moisture sensitivity level (MSL) 1 and RoHS-compliant finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN+ | Noninverting Input | High-impedance node (1000MΩ) for reference or sensor signal connection; CMVR extends to VSS. |
| 2 IN− | Inverting Input | High-impedance feedback node; bias current ≤100pA minimizes offset in high-Z networks. |
| 3 OUT | Amplifier Output | Rail-to-rail capable with 3mA drive; stable into 400pF - suitable for direct ADC or comparator interface. |
| 4 VSS | Negative Supply / Ground | Reference for single-supply operation; requires local 0.01µF bypass to minimize PSRR degradation. |
| 5 VDD | Positive Supply | Accepts +2.5V to +5.5V; PSRR = 82dB at DC ensures immunity to supply ripple in noisy automotive environments. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Swings within 20–30mV of rails at light loads, preserving >98% of supply voltage headroom for signal fidelity. |
| Low-input-bias-current BiCMOS input | IB ≤ ±100pA enables high-gain transimpedance designs (e.g., photodiode amps) without significant offset drift. |
| Unity-gain stable architecture | No external compensation required for gains ≥1, reducing BOM count and PCB area in space-constrained modules. |
| Automotive-grade temperature range | Specified from −40°C to +125°C - qualified for under-hood and cabin electronics without derating. |
| High open-loop gain | AVOL = 105dB ensures <0.001% gain error in closed-loop configurations with gain ≤100. |

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 |
|---|---|---|---|
| TSV911ICT | Higher 160µA IQ, wider 2.5V–36V supply range, lower 30kHz GBW, no AEC-Q200 qualification. | Suitable for industrial 24V systems but lacks automotive temp range guarantee and higher noise floor. | Select only if wide supply range outweighs power budget and automotive qualification needs. |
| MCP6001T-E/OT | Lower 100nA IQ, narrower 1.8V–6.0V supply, 1MHz GBW, specified only to +125°C (not −40°C to +125°C). | Valid for consumer portable gear but not qualified for automotive cold-start or under-hood thermal cycling. | Prefer for ultra-low-power battery apps where extended temperature coverage is unnecessary. |
Compared with TSV911ICT and MCP6001T-E/OT, the MAX4480AXK-T uniquely combines automotive-grade temperature range (−40°C to +125°C), 50µA IQ, rail-to-rail output, and 400pF capacitive-load stability - making it the only option qualified for harsh-environment sensor interfaces requiring both precision and reliability.

FAQ
What is the operating temperature range for the MAX4480AXK-T?
The MAX4480AXK-T is fully specified from −40°C to +125°C, meeting automotive AEC-Q100 stress test requirements for ambient temperature. This range is guaranteed across all electrical parameters in the datasheet, including input offset voltage, gain, and output swing - critical for under-hood and cabin electronics where thermal extremes occur.
Does the MAX4480AXK-T have a shutdown pin?
No, the MAX4480AXK-T does not include a shutdown function. That feature is exclusive to the MAX4481 variant (6-pin SC70/SOT23). The MAX4480AXK-T is a dedicated low-quiescent-current amplifier with fixed operation - simplifying design but requiring external power gating if system-level sleep modes are needed.
What package type is used for the MAX4480AXK-T?
The MAX4480AXK-T is supplied in a 5-pin SC70 package (package code X5+1, outline 21-0076), with dimensions 2.0mm × 1.25mm × 0.95mm. It is RoHS-compliant, tape-and-reel packaged (T suffix), and has MSL1 rating - compatible with standard reflow profiles and suitable for high-density PCB layouts.
Can the MAX4480AXK-T drive a 1000pF capacitive load?
No - the MAX4480AXK-T is unity-gain stable only up to 400pF. Driving 1000pF may cause peaking or oscillation. For heavier loads, add a series isolation resistor (e.g., 10–50Ω) between the output and capacitor, as documented in Figure 3 of the datasheet, to restore stability without compromising bandwidth significantly.
What is the typical input offset voltage drift of the MAX4480AXK-T?
The MAX4480AXK-T has a typical input offset voltage drift of ±3µV/°C, as specified in the Electrical Characteristics table. This low drift ensures minimal output error shift over temperature - especially valuable in precision DC amplification stages such as strain gauge or thermistor signal chains where calibration intervals must be extended.
