Product details
Overview
The MAX4092ASA+T from Maxim Integrated is a dual, micropower, single-supply, rail-to-rail input/output operational amplifier optimized for battery-powered instrumentation and precision low-voltage signal conditioning. It operates from 2.7V to 6V, draws ≤165µA per amplifier, delivers rail-to-rail output swing into 1kΩ, achieves 500kHz gain-bandwidth, and maintains 115dB open-loop voltage gain - enabling high-accuracy sensing in portable medical devices and industrial data acquisition systems.
For engineers reviewing the MAX4092ASA+T datasheet, MAX4092ASA+T pinout, MAX4092ASA+T application, or MAX4092ASA+T equivalent, this page provides verified DC accuracy (30µV offset), capacitive-load stability (2000pF), noise performance (12nV/√Hz), temperature range (–40°C to +125°C), and SO-8 package compatibility - all critical for low-power analog front-end design.
Technical Context
The MAX4092ASA+T integrates two independent bipolar op amps with complementary PNP/NPN input stages enabling beyond-the-rails™ input common-mode range (VEE – 0.05V to VCC + 0.05V) and no phase reversal under overdrive. Its folded-cascode architecture supports rail-to-rail output swing within 15mV of rails at 100kΩ load while maintaining unity-gain stability with ≥2000pF capacitive loads.
Each amplifier features precision trimming for low input offset (30µV typ), high CMRR (90dB) and PSRR (100dB), and low input bias current (20nA typ). The device's 12nV/√Hz input voltage noise and 0.20V/µs slew rate support accurate amplification of low-level sensor signals without compromising bandwidth or dynamic range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - enables direct operation from single Li-ion cell or 3.3V/5V system rails without level-shifting. |
| Quiescent Current | 165µA max per amplifier - allows continuous operation for years on coin-cell batteries in portable monitors. |
| Input Offset Voltage | 30µV typical - reduces DC error to <0.3mV in 100× gain stages, critical for precision thermocouple or strain-gauge interfaces. |
| Gain-Bandwidth Product | 500kHz - supports stable closed-loop gain up to 100× at 5kHz, sufficient for anti-aliasing and sensor signal conditioning. |
| Rail-to-Rail Output Swing | Within 15mV of VCC/VEE at 100kΩ - maximizes usable dynamic range in 3.3V systems, delivering >3.27Vpp output from 3.3V supply. |
| Capacitive Load Drive | Stable with ≥2000pF - eliminates need for external isolation resistors when driving ADC input capacitance or long PCB traces. |
| Input Voltage Noise | 12nV/√Hz at 10kHz - ensures minimal added noise in µV-level biomedical or environmental sensor amplifiers. |
Pinout & Package
MAX4092ASA+T is housed in an 8-pin SO (Small Outline) package with standard JEDEC MS-012AC footprint (5.0mm × 6.2mm, 1.27mm pitch). Pin 1 is marked with a bevelled corner or dot; the device is not pin-compatible with generic SO-8 op amps due to internal dual-amplifier topology and dedicated VEE/VCC routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of amplifier A - drives external load directly; rail-to-rail swing supports full-scale ADC interfacing. |
| 2 | IN1− | Inverting input of amplifier A - matched impedance required with IN1+ to minimize bias-current-induced offset. |
| 3 | IN1+ | Noninverting input of amplifier A - accepts signals beyond rails (VEE – 0.05V to VCC + 0.05V) without phase reversal. |
| 4 | VEE | Negative supply terminal - connected to ground in single-supply mode; must be bypassed with 0.1µF capacitor. |
| 5 | VCC | Positive supply terminal - accepts 2.7V–6V; requires local 0.1µF ceramic decoupling to suppress supply noise. |
| 6 | IN2+ | Noninverting input of amplifier B - electrically isolated from amplifier A; supports independent signal paths. |
| 7 | IN2− | Inverting input of amplifier B - shares same bias current and noise characteristics as IN1−/IN1+ pair. |
| 8 | OUT2 | Output of amplifier B - fully independent output stage; no crosstalk (125dB isolation at 1kHz) between channels. |
Key Features
| Feature | Design Value |
|---|---|
| Beyond-the-Rails™ Inputs | Common-mode range extends 50mV beyond VCC/VEE - enables direct interface to sensors operating outside supply rails (e.g., thermocouples, bridge outputs). |
| No Phase Reversal | Guaranteed non-inverting behavior even when inputs exceed rails - prevents latch-up and output glitches in overvoltage fault conditions. |
| Rail-to-Rail Output | Swings within 15mV of VCC/VEE into 100kΩ - preserves >99% of available voltage headroom in low-voltage systems. |
| Unity-Gain Stable w/ 2000pF | Drives heavy capacitive loads without external compensation - simplifies layout and eliminates isolation resistor in ADC driver applications. |
| High Channel Isolation | 125dB at 1kHz - prevents crosstalk between dual channels in multi-sensor monitoring or differential signal processing. |
Applications
| Portable ECG Monitor | Industrial 4–20mA Transmitter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher quiescent current (550µA vs. 165µA), lower GBW (6.4MHz), wider offset range (±1.6mV vs. ±1.4mV) | Better AC performance but unsuitable for multi-year battery life; requires larger supply bypassing | Select when higher speed (>100kHz closed-loop) outweighs power budget constraints |
| AD8602ARZ | Lower noise (12nV/√Hz same), higher offset drift (1.5µV/°C vs. 2µV/°C), no beyond-the-rails input | Lacks input overvoltage tolerance - requires external clamping for sensor fault protection | Select when absolute lowest offset (150µV max) is prioritized over input rail extension |
Compared with TLV2462IDR and AD8602ARZ, the MAX4092ASA+T uniquely balances ultra-low power (165µA), true beyond-the-rails input capability, and guaranteed 2000pF capacitive-load stability - making it optimal for space-constrained, battery-dependent analog front-ends where supply headroom and fault robustness are critical.

FAQ
What is the maximum capacitive load the MAX4092ASA+T can drive while remaining stable?
The MAX4092ASA+T is unity-gain stable with capacitive loads up to 2000pF, as confirmed in the Electrical Characteristics table and Figure 4 of the datasheet. This eliminates the need for external isolation resistors in most ADC driver and filter applications, unlike many competing micropower op amps that require compensation above 100pF.
Does the MAX4092ASA+T support true rail-to-rail input operation beyond the supply rails?
Yes, the MAX4092ASA+T features Beyond-the-Rails™ inputs with a common-mode range from VEE – 0.05V to VCC + 0.05V, and guarantees no phase reversal when inputs exceed this range. This allows direct interfacing with sensors whose output swings beyond the supply rails - a capability explicitly documented in the Applications Information section.
What is the typical input offset voltage specification for the MAX4092ASA+T?
The MAX4092ASA+T has a typical input offset voltage of 30µV, with a maximum of 1.4mV over temperature (–40°C to +125°C). This value is measured per amplifier and is critical for precision DC-coupled applications such as strain-gauge bridges or thermocouple amplifiers where offset error directly impacts measurement accuracy.
Can the MAX4092ASA+T operate from a single 3.3V supply?
Yes, the MAX4092ASA+T is fully specified for single-supply operation from 2.7V to 6V, including 3.3V. At 3.3V, it delivers rail-to-rail output swing within 15mV of both rails into 100kΩ, maintains 500kHz gain-bandwidth, and draws ≤165µA per amplifier - making it ideal for modern 3.3V embedded systems.
What package type is used for the MAX4092ASA+T and what are its key mechanical dimensions?
The MAX4092ASA+T uses an 8-pin SO (Small Outline) package compliant with JEDEC MS-012AC, measuring 5.0mm × 6.2mm with 1.27mm lead pitch. Pin 1 is identified by a bevelled corner or molded dot; thermal pad is not present. This package is compatible with standard SO-8 reflow profiles and automated assembly processes.
