Product details
Overview
MAX4483AUD from Maxim Integrated is a quad, rail-to-rail output operational amplifier optimized for low-power, single-supply systems. It delivers 50μA per amplifier quiescent current, operates from +2.5V to +5.5V, and maintains stable unity-gain performance with capacitive loads up to 400pF. It is specified across –40°C to +125°C and housed in a 14-pin TSSOP package for automotive and industrial sensor signal conditioning.
For engineers reviewing the MAX4483AUD datasheet, MAX4483AUD pinout, MAX4483AUD application, or MAX4483AUD equivalent, key selection criteria include its rail-to-rail output swing (≤80mV from rails at 5kΩ), 105dB open-loop gain, 0.005% THD at 100kΩ, 140kHz gain-bandwidth product, and guaranteed operation over extended temperature.
Technical Context
The MAX4483AUD integrates four independent BiCMOS op amps in a single monolithic die, each featuring rail-to-rail output stage capable of sourcing/sinking 3mA while maintaining low distortion. Its input stage provides ±100pA bias current, 1000MΩ input resistance, and common-mode range from VSS to VDD–1.3V.
Designed for unity-gain stability with up to 400pF load capacitance, it avoids external compensation in most buffer and signal-conditioning configurations. Phase margin is 70° and gain margin is 30dB at unity gain, enabling robust transient response without oscillation in typical sensor interface circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V - supports direct connection to Li-ion, 3.3V, or 5V system rails without regulation. |
| Quiescent Current per Amp | 50μA - enables multi-amp signal chains in battery-powered instruments with sub-200μA total bias. |
| Rail-to-Rail Output Swing | ≤80mV from VDD/VSS at 5kΩ - preserves full dynamic range in single-supply ADC driver and zero-crossing detector applications. |
| Open-Loop Gain (AVOL) | 105dB at 5kΩ load - ensures <0.001% gain error in precision amplification with moderate feedback resistors. |
| THD + Noise | 0.005% at 1kHz, 2VP-P, RL = 100kΩ - meets audio-grade and high-fidelity sensor signal integrity requirements. |
| Gain-Bandwidth Product | 140kHz - suitable for DC–10kHz sensor amplification, active filtering, and slow-control loop compensation. |
| Capacitive Load Stability | Stable up to 400pF - eliminates need for isolation resistors when driving long traces or ADC input capacitance. |
Pinout & Package
MAX4483AUD is packaged in a 14-pin Thin Shrink Small Outline Package (TSSOP) with standard 0.65mm pitch, RoHS-compliant, and rated for –40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 10 | Noninverting Inputs (INA+, INB+, INC+, IND+) | High-impedance (1000MΩ) inputs accepting signals from sensors, dividers, or reference sources. |
| 2, 6, 9, 13 | Inverting Inputs (INA−, INB−, INC−, IND−) | Accept feedback networks; support inverting gain configurations and differential sensing topologies. |
| 4, 7, 8, 14 | Outputs (OUTA, OUTB, OUTC, OUTD) | Rail-to-rail outputs capable of sourcing/sinking 3mA; drive ADCs, comparators, or analog switches directly. |
| 11, 12 | VDD / VSS | Single positive supply (2.5–5.5V) and ground return; require local 0.1μF bypass capacitor per supply pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Swings within 80mV of VDD/VSS at 5kΩ - maximizes usable signal swing in 3.3V/5V systems without level-shifting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM324DR | Higher 1.2mA per amp supply current; no rail-to-rail output; 700kHz GBW; wider VCC range (3–32V). | Not suitable for low-power or rail-to-rail output-critical designs; better for high-voltage industrial analog. | Select LM324DR only if supply voltage exceeds 5.5V or higher drive strength is required. |
| MCP6004-E/ST | Lower 1μA per amp supply current; rail-to-rail I/O; 1MHz GBW; same 14-TSSOP package; –40°C to +125°C rating. | Better for ultra-low-power designs but lower open-loop gain (90dB) and higher VOS (3.5mV max) than MAX4483AUD. | Choose MCP6004-E/ST when <100μA total supply budget is mandatory and gain accuracy <0.01% is acceptable. |
Compared with LM324DR and MCP6004-E/ST, MAX4483AUD uniquely balances ultra-low quiescent current (50μA), rail-to-rail output, high open-loop gain (105dB), and 400pF capacitive-load stability - making it optimal for automotive sensor interfaces where precision, power, and stability must coexist.

FAQ
What is the operating temperature range for MAX4483AUD?
The MAX4483AUD is fully specified for continuous operation from –40°C to +125°C. This automotive-grade temperature range is validated across all electrical parameters including input offset voltage, supply current, and open-loop gain, ensuring reliable performance in under-hood and industrial environments where thermal stress is critical. The MAX4483AUD datasheet guarantees these limits without derating.
Does MAX4483AUD support rail-to-rail input voltage range?
No, MAX4483AUD does not support rail-to-rail input. Its input common-mode voltage range is specified from VSS to VDD – 1.3V (at +25°C) or VDD – 1.4V (over full temperature range). This means the maximum allowable input voltage is ~3.7V when operating from a +5V supply. Input signals exceeding this limit may cause phase reversal or increased offset error. The MAX4483AUD does provide true rail-to-rail output swing, however.
Can MAX4483AUD drive an ADC input directly?
Yes, MAX4483AUD can drive many SAR and delta-sigma ADC inputs directly. Its rail-to-rail output swing (≤80mV from rails at 5kΩ), low THD (0.005%), and unity-gain stability up to 400pF allow clean interfacing with ADCs having input capacitances ≤400pF and input impedance ≥5kΩ. For ADCs with larger input capacitance, a small series resistor (e.g., 10–50Ω) is recommended to maintain stability.
Is MAX4483AUD pin-compatible with other devices in the MAX4480–MAX4483 family?
No, MAX4483AUD is not pin-compatible with MAX4480, MAX4481, or MAX4482 due to differing channel counts and pin assignments. The MAX4483AUD uses a 14-pin TSSOP with dedicated pins for four independent amplifiers (e.g., pins 1/2/4 for AMP A, 3/6/7 for AMP B, etc.), whereas MAX4482 uses an 8-pin SOT23 for dual amplifiers and MAX4480/4481 use 5- or 6-pin SC70 packages. Pin mapping is unique to each variant.
What is the maximum capacitive load MAX4483AUD can drive without oscillation?
The MAX4483AUD is unity-gain stable with capacitive loads up to 400pF, as confirmed in the datasheet's Electrical Characteristics table and Typical Operating Characteristics (Figure MAX4480 toc19). This specification applies under standard conditions (VDD = +5V, TA = +25°C, RL ≥ 1MΩ). Driving loads beyond 400pF requires external isolation (e.g., 10–100Ω series resistor) to preserve phase margin and prevent peaking or oscillation.
