Product details
Overview
MAX4336EUT-T 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 mode reducing supply current to <0.04μA - enabling low-power audio playback in compact handheld devices.
For engineers reviewing the MAX4336EUT-T datasheet, MAX4336EUT-T pinout, MAX4336EUT-T application, or MAX4336EUT-T equivalent, key selection criteria include rail-to-rail I/O swing into 32Ω loads, THD+N of 0.003% at 20kHz (10kΩ), PSRR of 90dB, thermal overload protection, and SC70-6 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4336EUT-T employs a BiCMOS process with dual NPN/PNP input stage enabling true rail-to-rail common-mode input range (GND to VCC) and output swing within 100mV of rails under light load. Its 5MHz GBWP supports wideband audio signal buffering without phase distortion up to 280kHz full-power bandwidth.
Shutdown control is implemented via dedicated SHDN pin (Pin 5), which places the output in high-impedance state and reduces quiescent current to <0.04μA per amplifier at VCC = 5V. Input protection includes 1kΩ series resistors and back-to-back diodes, limiting differential input voltage to ±1.2V before clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 5.5V single supply - enables direct integration with Li-ion (3.0–4.2V) or regulated 3.3V/5V rails without pre-regulation. |
| Output Drive Current | ±50mA - sufficient to drive 32Ω headphones at 2VP-P with <0.01% THD+N at 1kHz (2.7V supply). |
| Gain-Bandwidth Product | 5MHz - ensures stable unity-gain operation and preserves transient response fidelity across audio band. |
| THD+N @ 20kHz | 0.003% into 10kΩ - meets high-fidelity line-level buffer requirements with minimal harmonic contamination. |
| PSRR | 90dB - eliminates need for separate LDO pre-regulation in noisy battery-powered systems. |
| Shutdown Current | <0.04μA - extends battery life during audio pause/idle states without external power gating. |
| Input Offset Voltage | ±0.6mV (typ) - minimizes DC bias error in AC-coupled headphone outputs, reducing pop/click artifacts. |
Pinout & Package
MAX4336EUT-T is housed in a 6-pin SC70 package (package code X6SN+1, outline 21-0077), measuring 2.0mm × 1.25mm × 0.95mm - optimized for ultra-compact portable audio PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN+ | Noninverting Input | Accepts audio signal source; rail-to-rail CMVR (GND to VCC) allows direct coupling from DACs or biased sources. |
| 2 - IN− | Inverting Input | Feedback node for closed-loop gain setting; matched impedance critical to minimize offset from input bias current mismatch. |
| 3 - GND | Ground Reference | Primary return path for supply and signal currents; requires low-impedance connection to system ground plane. |
| 4 - OUT | Amplifier Output | Drives 32Ω load directly; rail-to-rail swing (≤100mV from rails at RL = 10kΩ) maximizes dynamic range. |
| 5 - SHDN | Shutdown Control | Active-low logic input; <0.3×VCC disables amplifier and forces high-Z output - enables software-controlled audio muting. |
| 6 - VCC | Positive Supply | Single 2.7–5.5V rail; requires local 0.1μF ceramic + ≥1μF bulk decoupling to suppress supply noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail I/O | Input common-mode range spans GND to VCC; output swings within 100mV of both rails at light load - preserves headroom in low-voltage portable designs. |
| 50mA Output Drive | Guaranteed sourcing/sinking capability into 32Ω - enables direct headphone driving without external boost stages or discrete transistors. |
| Ultra-Low Shutdown Current | <0.04μA per amplifier at VCC = 5V - reduces standby power to negligible levels in always-on audio subsystems. |
| 90dB PSRR | Rejects supply ripple across 10Hz–1MHz - permits use with switching regulators or noisy battery rails without audible hum. |
| Thermal Overload Protection | Auto-shutdown at TJ > +140°C; recovers at TJ < +120°C - prevents permanent damage during sustained high-current output 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+T | Higher 17MHz GBWP, lower 1.2mA ICC, but only 30mA output drive and no shutdown pin. | Better for wideband instrumentation; unsuitable for 32Ω headphone drive requiring 50mA. | Select MAX4336EUT-T when 50mA drive and hardware shutdown are mandatory; choose MAX4410ETB+T for higher-speed, lower-power line drivers. |
| TLC2272CDR | Lower 2.2MHz GBWP, 40mA output, no shutdown, SOIC-8 package (larger footprint). | Cost-optimized general-purpose audio buffer; lacks thermal protection and SC70 size. | Use MAX4336EUT-T where board space, thermal safety, and 50mA drive into 32Ω are required; TLC2272CDR fits legacy SOIC layouts with relaxed performance needs. |
Compared with MAX4410ETB+T and TLC2272CDR, the MAX4336EUT-T uniquely combines 50mA drive, SC70-6 footprint, active shutdown, and 90dB PSRR - making it the only option among the three qualified for space-constrained, battery-powered headphone driver designs demanding robust thermal and power management.

FAQ
What is the maximum output current capability of the MAX4336EUT-T?
The MAX4336EUT-T guarantees ±50mA output current into 32Ω loads at both 2.7V and 5.5V supply voltages. This is confirmed in the DC Electrical Characteristics table under "Output Drive" with VOH/VOL limits measured at ISOURCE/ISINK = 50mA. The device also features smart short-circuit protection that activates above 110mA, safeguarding MAX4336EUT-T during fault conditions.
Does the MAX4336EUT-T support true rail-to-rail input and output operation?
Yes, the MAX4336EUT-T provides true rail-to-rail input common-mode range (GND to VCC) and rail-to-rail output swing. The input stage uses complementary NPN/PNP pairs to extend the CMVR beyond the rails by ~0.25V, while the output stage achieves ≤100mV from either rail into 10kΩ and ≤500mV into 32Ω - verified in the "Output Voltage Swing" section of the datasheet.
How does the shutdown function work on the MAX4336EUT-T?
The MAX4336EUT-T uses Pin 5 (SHDN) as an active-low shutdown control. When pulled below 0.3×VCC, it reduces supply current to <0.04μA per amplifier and places the output in high-impedance state. Pulling SHDN ≥0.7×VCC enables normal operation. Enable/disable timing is specified as ≤5μs, and leakage into SHDN is ≤1μA - ensuring low-power, glitch-free muting in portable audio systems.
What is the typical THD+N performance of the MAX4336EUT-T at audio frequencies?
The MAX4336EUT-T achieves 0.003% THD+N at 20kHz into 10kΩ (VCC = 5V), and 0.01% at 1kHz into 32Ω (VCC = 2.7V). These values are measured with 2VP-P output and include noise - confirming suitability for high-fidelity headphone driver and line-buffer applications where harmonic distortion must remain below perceptible thresholds.
Is the MAX4336EUT-T compatible with capacitive loads, and what is its stability limit?
The MAX4336EUT-T is stable with capacitive loads up to 200pF without external compensation, as stated in the "Capacitive-Load Stability" specification. For larger loads (e.g., 330pF), adding a small isolation resistor (e.g., 39Ω) in series with the output restores stability - demonstrated in Figures 8–10 of the datasheet. This makes MAX4336EUT-T robust in PCB layouts with long traces or connector parasitics.
