Product details
Overview
MAX4483AUD+ from Maxim Integrated is a quad, rail-to-rail output operational amplifier optimized for low-power, single-supply operation across –40°C to +125°C. It draws 50μA per amplifier at 5V, delivers 3mA output drive, supports capacitive loads up to 400pF in unity-gain configuration, and achieves 105dB open-loop gain into 5kΩ - enabling precision signal conditioning in automotive sensor interfaces and portable instrumentation.
For engineers reviewing the MAX4483AUD+ datasheet, MAX4483AUD+ pinout, MAX4483AUD+ application, or MAX4483AUD+ equivalent, key selection criteria include its 14-pin TSSOP package, rail-to-rail output swing (≤80mV from rails), 140kHz gain-bandwidth product, 0.005% THD with 100kΩ load, and guaranteed operation over extended temperature.
Technical Context
The MAX4483AUD+ implements a BiCMOS input stage with rail-to-rail CMOS output stage, enabling full-swing operation from 2.5V to 5.5V supplies. Its input common-mode range extends from VSS to VDD – 1.3V, and it maintains ≥71dB CMRR and ≥82dB PSRR across the full supply and temperature range.
Designed for unity-gain stability with up to 400pF capacitive loads, the device uses internal compensation to avoid external phase compensation. Its 80V/ms slew rate and 50μs 0.1% settling time support moderate-speed signal acquisition without oscillation in high-impedance sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V - enables direct interface with Li-ion battery, 3.3V logic, and automotive 5V domains without level-shifting. |
| Quiescent Current per Amp | 50μA - allows four amplifiers to operate continuously on <200μA total, suitable for always-on sensor nodes. |
| Rail-to-Rail Output Swing | ≤80mV from rails into 5kΩ - preserves dynamic range in single-supply systems where ground-referenced signals must utilize full supply headroom. |
| Gain-Bandwidth Product | 140kHz - supports DC-coupled amplification and low-frequency filtering (e.g., <10kHz anti-aliasing) with stable phase margin. |
| Open-Loop Gain (AVOL) | 105dB into 5kΩ - ensures ≤0.003% gain error in precision buffer or gain-of-10 configurations with typical feedback networks. |
| Total Harmonic Distortion | 0.005% at 1kHz, 2VP-P, RL = 100kΩ - meets audio-grade and high-fidelity sensor signal integrity requirements. |
| Capacitive Load Stability | Stable up to 400pF - eliminates need for isolation resistors when driving ADC inputs, long traces, or EMI filters. |
Pinout & Package
MAX4483AUD+ is housed in a 14-pin Thin Shrink Small Outline Package (TSSOP), RoHS-compliant, with 0.65mm lead pitch and exposed pad not connected internally. Thermal resistance θJA = 9.1mW/°C above +70°C (727mW max at TA = +70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 12 | Noninverting Inputs (INA+, INB+, INC+, IND+) | High-impedance (≥1000MΩ) differential inputs accepting signals within VSS to VDD – 1.3V common-mode range. |
| 2, 6, 9, 13 | Inverting Inputs (INA–, INB–, INC–, IND–) | Matched to noninverting inputs; enable standard op-amp configurations including inverting gain stages and comparators. |
| 4, 7, 8, 14 | Outputs (OUTA, OUTB, OUTC, OUTD) | Rail-to-rail CMOS outputs sourcing/sinking 3mA; high-impedance state only applies to MAX4481 (not this part). |
| 10 | VDD | Positive supply input; requires 0.1μF bypass capacitor to VSS for noise immunity and stability. |
| 11 | VSS | Negative supply / ground reference; shared return path for all four amplifiers and bypass capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale analog output across entire supply range, maximizing SNR in single-supply data acquisition chains. |
| 140kHz GBW with 50μA quiescent current | Enables low-power, low-noise amplification of DC–10kHz signals without sacrificing bandwidth-efficiency trade-off. |
| Unity-gain stable with 400pF load | Eliminates need for output series resistors when interfacing directly to ADC inputs or long PCB traces. |
| 105dB open-loop gain into 5kΩ | Ensures <0.003% gain error in precision instrumentation buffers and transducer signal conditioning circuits. |
| 0.005% THD with 100kΩ load | Supports high-fidelity analog front-ends for infrared receivers and audio-capable sensor modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher quiescent current (550μA per amp), wider supply range (2.7V–6V), lower GBW (6.4MHz), no guaranteed 125°C operation. | Better for higher-speed, room-temperature applications; unsuitable for automotive under-hood use. | Select TLV2464IDR only if speed >1MHz is required and extended temperature is not needed. |
| LMV324IDR | Lower supply current (40μA per amp), narrower GBW (1MHz), rail-to-rail input/output, but only specified to +85°C. | Cost-optimized for consumer electronics; lacks AEC-Q200 qualification and 125°C guarantee. | Choose LMV324IDR for cost-sensitive, non-automotive applications where ambient temperature stays below 85°C. |
Compared with TLV2464IDR and LMV324IDR, MAX4483AUD+ uniquely combines automotive-grade temperature range (–40°C to +125°C), ultra-low 50μA quiescent current per amplifier, and guaranteed 400pF capacitive-load stability - making it the only option among the three qualified for harsh-environment, battery-constrained sensor signal chains requiring long-term reliability.

FAQ
What is the maximum capacitive load the MAX4483AUD+ can drive while remaining stable?
The MAX4483AUD+ 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 specification applies across the full –40°C to +125°C temperature range and 2.5V–5.5V supply range. No external compensation is required for loads ≤400pF, making MAX4483AUD+ suitable for direct connection to ADC inputs and EMI filter networks without added series resistance.
Does the MAX4483AUD+ include a shutdown feature?
No, the MAX4483AUD+ does not include a shutdown feature. Shutdown functionality is exclusive to the MAX4481 variant (single amplifier with SHDN pin). The MAX4483AUD+ is a quad amplifier with no dedicated shutdown terminal; all four amplifiers remain active whenever VDD and VSS are powered. This is explicitly stated in the Selector Guide table and Pin Description section of the datasheet.
What is the input offset voltage specification for the MAX4483AUD+?
The MAX4483AUD+ has a guaranteed input offset voltage of ±5.5mV maximum over the full –40°C to +125°C temperature range, and ±1mV typical at +25°C. This value is specified in the Electrical Characteristics table under "Input Offset Voltage (VOS)" and applies to all amplifiers in the quad package. The offset voltage drift is ±3μV/°C, supporting stable DC-coupled gain accuracy in wide-temperature applications.
Can the MAX4483AUD+ operate from a 2.5V supply?
Yes, the MAX4483AUD+ is fully specified to operate from a minimum supply voltage of +2.5V up to +5.5V. At 2.5V, quiescent current remains ≤100μA per amplifier (typical 45μA), rail-to-rail output swing is maintained, and all key parameters-including GBW, AVOL, and THD-remain within datasheet limits. This enables direct compatibility with 2.5V logic domains and single-cell lithium primary batteries.
What package type is used for the MAX4483AUD+?
The MAX4483AUD+ uses a 14-pin Thin Shrink Small Outline Package (TSSOP) with RoHS-compliant lead finish ("+" suffix), 0.65mm lead pitch, and no internal thermal pad connection. This package is documented in the Ordering Information table and Package Information section, and matches land pattern number 90-0113 per Maxim's package database.
