Product details
Overview
MAX4336EXT from Maxim Integrated is a single-channel, rail-to-rail input/output operational amplifier optimized for 32Ω headphone driver applications in portable battery-powered systems. It delivers 50mA output current, features 5MHz gain-bandwidth product, operates from 2.7V to 5.5V single supply, and includes shutdown/mute mode reducing supply current to 0.04µA per amplifier.
For engineers reviewing the MAX4336EXT datasheet, MAX4336EXT pinout, MAX4336EXT application, or MAX4336EXT equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, confirmed audio interface use cases, and two rigorously cross-checked alternative parts with documented functional differences.
Technical Context
The MAX4336EXT uses a BiCMOS process with dual NPN/PNP input stage enabling true rail-to-rail input common-mode range (GND to VCC) and rail-to-rail output swing within 400mV of rails into 32Ω. Its 5MHz GBWP supports wideband audio fidelity while maintaining stability with capacitive loads up to 200pF.
Shutdown control is implemented via dedicated SHDN pin: logic-low disables the amplifier, forces output to high-impedance state, and reduces ICC(SHDN) to <0.04µA at VCC = 5V. Thermal overload protection activates at +140°C junction temperature, limiting current and placing outputs in high-Z until cooling to +120°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V single supply - enables direct integration with Li-ion/Li-poly battery systems without pre-regulation. |
| Output Drive Current | ±50mA - sufficient to drive 32Ω headphones at 2VP-P with low distortion and full dynamic range. |
| Gain-Bandwidth Product | 5MHz - supports flat frequency response up to 20kHz with adequate phase margin for audio buffer applications. |
| THD + Noise | 0.003% at 20kHz into 10kΩ - ensures high-fidelity signal reproduction with minimal harmonic artifacts. |
| PSRR | 90dB - eliminates need for separate LDO pre-regulation in noisy digital power domains. |
| Shutdown Current | <0.04µA - extends battery life during audio pause or standby modes in portable devices. |
| Rail-to-Rail I/O | Input CM range: GND to VCC; Output swing: within 400mV of rails into 32Ω - maximizes usable voltage headroom. |
Pinout & Package
MAX4336EXT is housed in a 6-pin SC70 package (3.0mm × 1.8mm × 0.9mm), optimized for space-constrained portable audio designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Noninverting Input | Accepts audio signal source; rail-to-rail input stage allows full-swing AC-coupled or DC-coupled inputs. |
| 2 (IN−) | Inverting Input | Feedback node for closed-loop configurations; matched impedance critical to minimize offset error from bias current polarity reversal. |
| 3 (OUT) | Amplifier Output | Drives 32Ω load directly; high-current capability supports peak currents up to 110mA before short-circuit protection engages. |
| 4 (GND) | Analog Ground Reference | Primary return path for output current and bias currents; must be low-impedance and separated from digital ground. |
| 5 (SHDN) | Shutdown Control Input | Active-low logic input; pulls to GND to enter ultra-low-power shutdown (0.04µA), connects to VCC for normal operation. |
| 6 (VCC) | Positive Supply Rail | Single 2.7V–5.5V supply input; requires local 0.1µF ceramic + ≥1µF bulk bypassing for stable audio performance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Enables maximum signal swing from GND to VCC in single-supply portable systems, preserving SNR and dynamic range. |
| 50mA Output Drive | Directly drives 32Ω headphones without external boost stages, simplifying BOM and PCB layout in compact form factors. |
| 0.04µA Shutdown Current | Reduces system quiescent power by >99.9% during mute/sleep, extending battery runtime in always-on audio interfaces. |
| 90dB PSRR | Rejects noise from shared switch-mode power supplies, eliminating need for costly analog LDOs in mixed-signal designs. |
| Thermal Overload Protection | Automatically disables output and limits current at +140°C junction temperature, preventing permanent damage during sustained high-load conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail, high-output-current op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4410ETB+ | Same SC70-6 package, 60mA output, 10MHz GBWP, but no shutdown pin; higher quiescent current (2.5mA vs. 1.2mA). | Lacks hardware mute control; unsuitable for battery-critical sleep modes requiring sub-µA shutdown. | Select when higher bandwidth and output current are prioritized over ultra-low-power shutdown capability. |
| TLC2271CD | SOIC-8 package, 40mA output, 2.2MHz GBWP, rail-to-rail output only (not input), no thermal protection. | Requires larger PCB area; limited input voltage range restricts use with near-rail DC-coupled sources. | Select when SOIC packaging is acceptable and thermal safety margin is managed externally. |
Compared with MAX4336EXT, MAX4410ETB+ offers higher bandwidth and output current but sacrifices shutdown functionality and increases static power, while TLC2271CD trades package size, bandwidth, and input rail-to-rail capability for broader vendor availability and lower cost in non-battery-sensitive applications.

FAQ
What is the operating supply voltage range for MAX4336EXT?
The MAX4336EXT operates from a single 2.7V to 5.5V supply. This range supports direct connection to Li-ion batteries (nominal 3.7V, discharged to ~2.8V) and regulated 3.3V or 5V rails. Operation below 2.7V is not guaranteed, and absolute maximum supply is 6V.
Does MAX4336EXT support rail-to-rail input and output?
Yes, MAX4336EXT features true rail-to-rail input and output stages. The input common-mode voltage range extends from GND to VCC, and the output can swing within 400mV of both rails into a 32Ω load at VCC = 2.7V - critical for maximizing dynamic range in single-supply audio systems.
How does the shutdown function work on MAX4336EXT?
The MAX4336EXT's SHDN pin (Pin 5) is active-low: pulling it to GND places the amplifier in shutdown mode, reducing supply current to <0.04µA and forcing the output into high-impedance state. Connecting SHDN to VCC enables normal operation. No external pull-up is required.
What is the maximum capacitive load MAX4336EXT can drive stably?
MAX4336EXT is stable driving capacitive loads up to 200pF with resistive loads referenced to VCC/2. For loads exceeding 200pF (e.g., 330pF), adding a 39Ω isolation resistor in series with the output restores stability, as verified in typical operating characteristics Figure 10.
Is thermal protection built into MAX4336EXT?
Yes, MAX4336EXT includes integrated thermal overload protection. When junction temperature exceeds +140°C, the device reduces supply current to 120µA per amplifier and places outputs in high-impedance state. Normal operation resumes once junction temperature falls below +120°C.
