Product details
Overview
MAX4483ASD+T from Maxim Integrated is a quad, rail-to-rail output operational amplifier designed for low-power, single-supply signal conditioning in harsh environments. It operates from +2.5V to +5.5V, draws 50μA per amplifier, delivers 3.0mA output drive, and is specified across –40°C to +125°C for automotive and industrial applications including sensor signal detection and infrared receivers.
For engineers reviewing the MAX4483ASD+T datasheet, MAX4483ASD+T pinout, MAX4483ASD+T application, or MAX4483ASD+T equivalent, this page provides verified electrical parameters, TSSOP-14 package mapping, real-world use cases, and validated alternative op amps with documented functional and application-level differences.
Technical Context
The MAX4483ASD+T implements a BiCMOS input stage with rail-to-rail output swing, enabling full-scale signal handling in single-supply systems. Its unity-gain stability supports capacitive loads up to 400pF without external compensation, and its 140kHz gain-bandwidth product suits precision DC-coupled amplification and low-frequency filtering.
Each of its four amplifiers features matched input bias current (±100pA max), 105dB open-loop gain into 5kΩ, and <0.005% THD at 1kHz with 100kΩ load - characteristics critical for high-fidelity sensor front-ends and zero-crossing detection circuits where offset, noise, and distortion directly impact system accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V - enables direct interface with Li-ion, 3.3V, and 5V logic rails without level-shifting. |
| Quiescent Current per Amplifier | 50μA - allows battery-powered operation for >1 year in always-on sensor nodes with four active channels. |
| Rail-to-Rail Output Swing | VOL = 8mV / VOH = 80mV (RL = 5kΩ) - preserves dynamic range near supply rails for maximum ADC utilization. |
| Open-Loop Gain (AVOL) | 105dB into 5kΩ - ensures <1mV error in unity-gain buffer configurations with typical source impedances. |
| Input Offset Voltage (VOS) | ±5.5mV max - supports accurate DC-coupled amplification of mV-level thermocouple or bridge outputs. |
| Gain-Bandwidth Product | 140kHz - sufficient for anti-aliasing filters, slow-settling instrumentation, and 1kHz sensor signal conditioning. |
| Capacitive Load Stability | Stable up to 400pF - eliminates need for isolation resistors when driving ADC inputs or long PCB traces. |
Pinout & Package
MAX4483ASD+T is housed in a 14-pin TSSOP package (package code U14+1, outline 21-0066), optimized for high-density industrial PCBs with thermal performance up to 727mW at +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 12 | IN+ (A/B/C/D) | Noninverting inputs for each of four independent amplifiers - high-impedance (1000MΩ) node for sensor/bridge connections. |
| 2, 4, 6, 13 | IN− (A/B/C/D) | Inverting inputs - matched to IN+ for differential gain configuration and common-mode rejection. |
| 7, 8, 9, 14 | OUT (A/B/C/D) | Amplifier outputs capable of sourcing/sinking 3mA - drives 5kΩ loads while maintaining rail-to-rail swing. |
| 10, 11 | VDD / VSS | Positive and negative supply pins - require local 0.1μF bypass capacitors to ground for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output voltage swing | Swings within 8mV of VSS and 80mV of VDD into 5kΩ - maximizes usable signal range in single-supply data acquisition. |
| Low quiescent current (50μA per amp) | Enables four-channel amplification with total IDD < 200μA - ideal for energy-constrained IoT sensor nodes. |
| Unity-gain stability with 400pF load | Eliminates need for output series resistance when interfacing to ADCs or long traces - simplifies layout and reduces BOM count. |
| –40°C to +125°C operating range | Qualified for under-hood automotive, industrial motor control, and outdoor equipment - no derating required. |
| High CMRR (86dB typ) and PSRR (92dB typ) | Rejects supply ripple and common-mode noise in noisy environments - critical for precision analog front-ends. |
Applications
| Single-Supply Zero-Crossing Detectors | Sensor Signal Detection |

| Infrared Receivers | Electronic Ignition Modules |
Use Scenario: Conditioning weak, modulated IR photodiode signals in remote controls or proximity sensors operating at 38kHz carrier frequency. IC Role / Device Role / Timing Role: Bandpass-filtering and DC-bias restoration stage before demodulation - leverages low THD and wide supply range. Use Value: 0.005% THD at 1kHz and 140kHz GBW support clean amplification of narrowband IR pulses without harmonic distortion. |
Use Scenario: Monitoring coil current and crankshaft position signals in 12V automotive ignition systems exposed to engine bay temperatures up to +125°C. IC Role / Device Role / Timing Role: Signal conditioner for Hall-effect or VR sensor outputs feeding microcontroller ADCs in engine control units. Use Value: Guaranteed operation from –40°C to +125°C and 86dB CMRR suppress ignition noise - eliminates cold-start failures and EMI-induced misfires. |
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), lower GBW (6.4MHz), no guaranteed +125°C operation. | Not qualified for automotive under-hood use; suitable only for commercial-temperature portable instruments. | Select only if higher speed and rail-to-rail input are required - not a drop-in replacement for MAX4483ASD+T's low-power, high-temp profile. |
| LMV324DR | Lower supply voltage floor (2.7V min), no rail-to-rail output (VOL = 150mV), wider VOS range (±7mV). | Limited to 3.3V/5V systems above ambient temperature; unsuitable for 2.5V battery or extended-temperature designs. | Consider for cost-sensitive consumer applications where 125°C rating and 2.5V operation are unnecessary. |
Compared with TLV2464IDR and LMV324DR, MAX4483ASD+T uniquely combines 50μA per amplifier, guaranteed –40°C to +125°C operation, and rail-to-rail output in a 14-pin TSSOP - making it the only option among the three for automotive-grade, ultra-low-power quad amplification.

FAQ
What is the operating temperature range of the MAX4483ASD+T?
The MAX4483ASD+T is fully specified from –40°C to +125°C, with all electrical parameters guaranteed across this automotive-grade temperature range. This includes quiescent current, input offset voltage, open-loop gain, and rail-to-rail output swing - ensuring consistent performance in engine control units, industrial motor drives, and outdoor environmental sensors where thermal stress is critical.
Does the MAX4483ASD+T include shutdown functionality?
No, the MAX4483ASD+T does not feature a shutdown pin. Shutdown capability is exclusive to the MAX4481 variant (single amplifier with SHDN pin). The MAX4483ASD+T is a quad amplifier without enable/disable control - its four channels remain active whenever powered within the +2.5V to +5.5V supply range.
What package type is used for the MAX4483ASD+T?
The MAX4483ASD+T uses a 14-pin TSSOP package (package code U14+1, outline 21-0066), RoHS-compliant and lead(Pb)-free. It measures 5.0mm × 4.4mm × 1.2mm and supports surface-mount reflow assembly - compatible with standard SMT processes and offering better thermal dissipation than SOIC equivalents.
Can the MAX4483ASD+T drive capacitive loads without oscillation?
Yes, the MAX4483ASD+T is unity-gain stable with capacitive loads up to 400pF, as confirmed in the datasheet's Electrical Characteristics and Typical Operating Characteristics sections. This allows direct connection to ADC input capacitors, long PCB traces, or piezoelectric transducers without requiring external isolation resistors or compensation networks.
What is the typical input bias current of the MAX4483ASD+T?
The MAX4483ASD+T has a typical input bias current of ±0.1pA and a maximum of ±100pA over temperature - enabled by its BiCMOS input stage. This ultra-low bias current minimizes voltage errors when amplifying signals from high-impedance sources such as pH electrodes, photodiodes, or ceramic microphone elements.
