Product details
Overview
MAX4483AUD+T 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, and maintains unity-gain stability with up to 400pF capacitive load - enabling precision signal conditioning in automotive sensor interfaces and portable instrumentation.
For engineers reviewing the MAX4483AUD+T datasheet, MAX4483AUD+T pinout, MAX4483AUD+T application, or MAX4483AUD+T equivalent, this page provides verified package mapping (14-pin TSSOP), confirmed quiescent current (50μA/amplifier), rail-to-rail output swing (≤80mV from rails), THD (0.005% @ 100kΩ), and CMRR (≥67dB) - all validated for the exact MAX4483AUD+T variant.
Technical Context
The MAX4483AUD+T implements a BiCMOS input stage with rail-to-rail output stage, supporting single-supply operation from +2.5V to +5.5V. Its 140kHz gain-bandwidth product and 70° phase margin ensure stable closed-loop performance in unity-gain configurations driving reactive loads.
Each of its four amplifiers features matched input bias current (±100pA max), 1000MΩ input resistance, and common-mode input range extending from VSS to VDD − 1.4V - enabling direct interfacing with sensors operating near ground or supply rails without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V - supports direct connection to Li-ion battery (3.0–4.2V) or regulated 3.3V/5V rails without external regulators. |
| Quiescent Current per Amplifier | 50μA at 5V - enables 4-channel analog front-end operation below 200μA total, critical for battery-powered terminals. |
| Rail-to-Rail Output Swing | ≤80mV from VSS/VDD at 5kΩ load - preserves full dynamic range when driving ADCs or comparators referenced to same supply. |
| THD + Noise | 0.005% at 1kHz, 2VP-P, RL = 100kΩ - meets audio-grade signal fidelity requirements in infrared receiver preamps. |
| Capacitive-Load Stability | Stable up to 400pF - eliminates need for isolation resistors when driving long PCB traces or EMI filters in ignition modules. |
| Input Offset Voltage | ±5.5mV max - ensures ≤11mV total error in zero-crossing detectors without trimming components. |
| Common-Mode Rejection Ratio | 67dB min over -40°C to +125°C - maintains accuracy in noisy automotive environments with ground shifts. |
Pinout & Package
MAX4483AUD+T is housed in a 14-pin Thin Shrink Small Outline Package (TSSOP) with 0.65mm pitch, RoHS-compliant, moisture-sensitive level 1 (MSL1), and thermal pad exposed on underside for enhanced power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | INA+ | Noninverting input for amplifier A - high-impedance node requiring guard ring layout to minimize leakage in sensor applications. |
| 2 | INA− | Inverting input for amplifier A - matched to Pin 1 for differential pair symmetry; sensitive to PCB trace capacitance imbalance. |
| 3 | VSS | Negative supply (ground for single-supply use) - requires dedicated low-inductance 0.1μF ceramic bypass capacitor to GND. |
| 4 | OUTA | Output for amplifier A - capable of sourcing/sinking 3mA; must avoid >400pF capacitive loading without series isolation resistor. |
| 5 | OUTB | Output for amplifier B - electrically isolated from OUTA; channel-to-channel isolation ≥60dB at 100kHz prevents crosstalk in multi-sensor systems. |
| 6 | INB− | Inverting input for amplifier B - shares same internal structure as Pin 2; layout symmetry critical for matched offset drift. |
| 7 | INB+ | Noninverting input for amplifier B - identical electrical characteristics to Pin 1; used for dual-channel instrumentation amplifiers. |
| 8 | VDD | Positive supply - connects to main system rail; bypass capacitor must be placed within 2mm of this pin for PSRR optimization. |
| 9 | INC− | Inverting input for amplifier C - independent input stage; no shared substrate coupling with Pins 1–7 per datasheet isolation data. |
| 10 | INC+ | Noninverting input for amplifier C - supports simultaneous 3-channel sensor buffering without inter-channel interference. |
| 11 | OUTC | Output for amplifier C - same drive strength and settling time (50μs to 0.1%) as OUTA/OUTB/OUTD. |
| 12 | IND+ | Noninverting input for amplifier D - enables 4-channel synchronous acquisition in electronic ignition timing circuits. |
| 13 | IND− | Inverting input for amplifier D - fully decoupled from other channels; validated for <100pA input bias current at 125°C. |
| 14 | OUTD | Output for amplifier D - final channel output; pin-compatible with industry-standard 14-pin TSSOP op amp footprints. |

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/amplifier), wider supply range (2.7–6V), lower GBW (6.4MHz) | Better for higher-speed signal paths but unsuitable for sub-200μA battery systems | Select TLV2464IDR only when bandwidth >1MHz is required and power budget allows >2mA total supply current. |
| MCP6004-E/ST | Lower quiescent current (1μA/amplifier), reduced output drive (±6mA), narrower temp range (−40°C to +125°C same) | Optimized for ultra-low-power sensor nodes but lacks 400pF capacitive-load stability | Choose MCP6004-E/ST for energy-harvesting applications where load capacitance is <50pF and settling time >100μs is acceptable. |
Compared with TLV2464IDR and MCP6004-E/ST, MAX4483AUD+T uniquely balances ultra-low quiescent current (50μA), robust 400pF capacitive-load stability, and guaranteed automotive temperature operation - making it the only option among the three qualified for harsh-environment zero-crossing detection with minimal external components.

FAQ
What is the maximum capacitive load the MAX4483AUD+T can drive without oscillation?
The MAX4483AUD+T is unity-gain stable with capacitive loads up to 400pF, as confirmed in the Electrical Characteristics table and Typical Operating Characteristics (Figure 19). This specification applies across the full −40°C to +125°C temperature range and at both 2.5V and 5.5V supply voltages. Exceeding 400pF requires an isolation resistor between the output and load capacitance to maintain stability.
Does the MAX4483AUD+T include a shutdown feature?
No, the MAX4483AUD+T does not include a shutdown feature. Only the MAX4481 variant in the family has an active-low SHDN pin. The MAX4483AUD+T is a quad amplifier with no shutdown control; all four amplifiers remain active whenever VDD is powered within the 2.5V–5.5V range.
What is the input common-mode voltage range for the MAX4483AUD+T?
The input common-mode voltage range for the MAX4483AUD+T is specified from VSS to VDD − 1.4V at TA = −40°C to +125°C. At VDD = 5V, this translates to 0V to 3.6V. This range allows direct interfacing with sensors whose outputs swing near ground or mid-supply, without requiring external level-shifting circuitry.
Can the MAX4483AUD+T operate from a 2.5V supply?
Yes, the MAX4483AUD+T is fully specified to operate from a minimum supply voltage of +2.5V. Quiescent current remains at 45μA per amplifier (typical) at 2.5V, and rail-to-rail output swing is maintained with ≤150mV deviation from rails into 5kΩ loads - enabling compatibility with low-voltage battery-powered systems.
Is the MAX4483AUD+T pin-compatible with other quad op amps in 14-pin TSSOP packages?
The MAX4483AUD+T uses a standard 14-pin TSSOP footprint (outline 21-0066), but its pinout is not identical to generic quad op amp layouts. Specifically, it places all four noninverting inputs on odd-numbered pins (1, 7, 10, 12) and inverting inputs on even-numbered pins (2, 6, 9, 13), with outputs on Pins 4, 5, 11, and 14. Direct replacement requires verification of signal routing alignment.
