Product details
Overview
MAX4488AUT#G16 from Maxim Integrated is a single-channel, low-noise, low-distortion, rail-to-rail output operational amplifier optimized for high-fidelity signal conditioning. It features 42MHz gain-bandwidth product (AV ≥ +5V/V), 0.0004% THD+N at 1kHz (RL = 1kΩ), 4.5nV/√Hz input voltage-noise density, and shutdown capability reducing supply current to 0.01µA - enabling precision ADC buffering and microphone preamplification in space-constrained, battery-sensitive designs.
For engineers reviewing the MAX4488AUT#G16 datasheet, MAX4488AUT#G16 pinout, MAX4488AUT#G16 application, or MAX4488AUT#G16 equivalent, key selection criteria include its decompensated stability (minimum gain +5V/V), SOT23-6 package footprint, shutdown control interface, and verified performance under 2.7V–5.5V single-supply operation with ground-sensing inputs.
Technical Context
The MAX4488AUT#G16 is internally compensated for non-inverting gains of +5V/V or higher, delivering 10V/µs slew rate and 1.25MHz full-power bandwidth. Its BiCMOS process enables ultra-low input bias current (1pA typ) and exceptional DC accuracy (70µV VOS, 120dB AVOL), supporting high-impedance sensor interfaces without significant offset or loading error.
It integrates a dedicated SHDN pin (Pin 5) that places the output in high-impedance state and reduces quiescent current to 0.01µA - critical for power-gated signal chains. Input common-mode range extends to VSS – 0.1V and up to VDD – 1.7V, ensuring robust operation with ground-referenced sources and rail-to-rail output swing within 8mV of supplies (RL = 10kΩ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 42MHz - supports stable closed-loop operation at AV ≥ +5V/V, enabling wideband filtering and fast settling in data acquisition front-ends. |
| THD+N | 0.0004% at 1kHz, RL = 1kΩ - preserves signal integrity in 16-bit+ ADC/DAC interfaces where harmonic distortion directly impacts ENOB. |
| Input Voltage-Noise Density | 4.5nV/√Hz at 1kHz - minimizes added noise in low-level sensor amplification (e.g., strain gauges, piezoelectric transducers). |
| Supply Voltage Range | +2.7V to +5.5V - enables direct interfacing with Li-ion, 3.3V, and 5V systems without level-shifting or charge-pump support. |
| Quiescent Current (Normal) | 2.5mA per amplifier - balances speed and power for always-on analog signal paths in portable instrumentation. |
| Shutdown Current | 0.01µA - allows microcontroller-controlled power gating to extend battery life in intermittent-sampling applications. |
| Input Offset Voltage | ±70µV (typ) - ensures sub-LSB error in 16-bit systems with ±2.5V full-scale range (e.g., 38.1µV LSB). |
Pinout & Package
MAX4488AUT#G16 is supplied in a RoHS-compliant, lead-free 6-pin SOT23 package (package code U6F-6), with exposed pad (not present in SOT23 variant) and top mark "AAZW". Pin 1 is OUT; Pin 2 is IN−; Pin 3 is IN+; Pin 4 is VSS; Pin 5 is SHDN; Pin 6 is VDD.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier Output | Rail-to-rail push-pull stage drives 1kΩ loads while maintaining DC accuracy; outputs high-impedance when SHDN = low. |
| 2 | Inverting Amplifier Input | High-impedance node (1000GΩ) with 10pF input capacitance; requires feed-forward compensation (CZ) if RG||RF > 5kΩ. |
| 3 | Noninverting Amplifier Input | Ground-sensing input (VCM down to VSS − 0.1V); immune to phase reversal during overdrive. |
| 4 | Negative Supply | Connect to ground in single-supply mode; reference for internal biasing and output stage. |
| 5 | Shutdown Input | Active-low logic control (VIH = 0.7×VDD, VIL = 0.3×VDD); 1.5µs delay to shutdown, 10µs enable time from shutdown. |
| 6 | Positive Supply | Accepts 2.7V–5.5V; bypass with 0.1µF ceramic capacitor placed adjacent to pin for PSRR optimization. |
Key Features
| Feature | Design Value |
|---|---|
| Decompensated GBW | 42MHz stable only at AV ≥ +5V/V - enables higher closed-loop bandwidth than unity-gain stable op-amps with same power budget. |
| Ultra-Low THD+N | 0.0004% at 1kHz into 1kΩ - meets stringent audio and medical instrumentation linearity requirements without post-processing correction. |
| Sub-100pA Input Bias Current | 1pA typical - eliminates voltage error across high-value feedback networks (e.g., 1MΩ gain-setting resistors add <1µV offset). |
| Rail-to-Rail Output Swing | Within 8mV of VDD/VSS at RL = 10kΩ - maximizes dynamic range in low-voltage systems (e.g., 3.3V ADC references). |
| Integrated Shutdown Control | Dedicated SHDN pin reduces IDD to 0.01µA - simplifies power sequencing vs. external MOSFET gating and avoids leakage path complications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA1611AIDBVR | 30MHz GBW, unity-gain stable, 1.1nV/√Hz noise, no shutdown pin | Better noise performance but lower bandwidth and no power-gating capability | Select when lowest possible input noise dominates over shutdown need and gain ≤ +1V/V is acceptable |
| ADA4898-1ARMZ | 65MHz GBW, unity-gain stable, 1.1nV/√Hz noise, 1.2mA quiescent current | Higher speed and lower noise, but lacks shutdown and consumes more power | Select for high-speed photodiode transimpedance or RF IF amplification where continuous operation is required |
Compared with OPA1611AIDBVR and ADA4898-1ARMZ, the MAX4488AUT#G16 trades 1.1nV/√Hz noise and unity-gain stability for integrated shutdown, 42MHz bandwidth at AV ≥ +5V/V, and SOT23-6 footprint - making it optimal for battery-powered, gain-fixed, medium-bandwidth precision signal chains.

FAQ
What is the minimum stable gain for MAX4488AUT#G16?
The MAX4488AUT#G16 is internally compensated for non-inverting closed-loop gains of +5V/V or greater. Attempting to use it at unity gain or AV = +2V/V risks instability and oscillation due to insufficient phase margin. For lower gains, consider the unity-gain stable MAX4475AUT#G16 instead.
Does MAX4488AUT#G16 support single-supply operation?
Yes, MAX4488AUT#G16 operates from a single +2.7V to +5.5V supply. Its input common-mode range includes ground (VSS − 0.1V), and its rail-to-rail output swings within 8mV of both supply rails with a 10kΩ load - making it ideal for 3.3V and 5V systems without dual supplies.
What is the purpose of the SHDN pin on MAX4488AUT#G16?
The SHDN pin (Pin 5) is an active-low control that disables the amplifier core and places the output in high-impedance state while reducing quiescent supply current to 0.01µA. This feature enables microcontroller-driven power gating in battery-operated devices to extend runtime between measurements.
Can MAX4488AUT#G16 drive capacitive loads?
Yes, MAX4488AUT#G16 is stable driving capacitive loads up to 200pF without external compensation. For loads >100pF, verify phase margin using the recommended feed-forward capacitor (CZ = 10 × RF/RG pF) between IN− and OUT to maintain stability in high-gain configurations.
What package type is used for MAX4488AUT#G16?
MAX4488AUT#G16 is packaged in a 6-pin SOT23 (U6F-6 outline) with RoHS-compliant, lead-free finish and top-mark "AAZW". It does not include an exposed thermal pad - unlike the TDFN variant (MAX4488ATT#G16) - and requires standard SOT23 land pattern #90-0175.
