Product details
Overview
MAX4130EUK from Maxim Integrated is a single, rail-to-rail input/output operational amplifier optimized for low-voltage, single-supply precision signal conditioning. It delivers 10MHz gain-bandwidth, 900µA quiescent current per amplifier, ±200µV typical offset voltage, and operates from +2.7V to +6.5V. It is widely used in battery-powered data-acquisition systems requiring rail-to-rail swing and stable unity-gain performance.
For engineers reviewing the MAX4130EUK datasheet, MAX4130EUK pinout, MAX4130EUK application, or MAX4130EUK equivalent, key selection criteria include its SOT23-5 package compatibility, guaranteed -40°C to +85°C operation, rail-to-rail I/O capability at 2.7V minimum supply, 160pF capacitive-load stability, and absence of shutdown functionality-distinguishing it from the MAX4131/MAX4133 variants.
Technical Context
The MAX4130EUK employs a dual-input-stage architecture (NPN/PNP) enabling rail-to-rail common-mode input range extending 200mV beyond VEE and VCC. Its output stage supports full rail-to-rail swing into 250Ω loads while maintaining unity-gain stability without external compensation.
Unlike the MAX4131/33, the MAX4130EUK lacks a shutdown pin and is specified only in the 5-pin SOT23 package. Its DC accuracy-including ±3.5mV max input offset voltage over temperature-is validated across the full -40°C to +85°C industrial range, with parameters guaranteed by design per Note 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 10MHz - enables stable amplification of signals up to ~1MHz at moderate closed-loop gains (e.g., AV = 10). |
| Supply Voltage Range | +2.7V to +6.5V single supply - supports direct integration into 3V and 5V battery-powered systems without level-shifting. |
| Input Offset Voltage (max) | ±3.5mV over -40°C to +85°C - ensures <0.1% error in 12-bit ADC front-end applications at room and extended temperature. |
| Quiescent Current | 1.2mA max per amplifier at +85°C - balances speed and power for always-on sensor interfaces in portable equipment. |
| Output Swing (RL = 250Ω) | VOL ≤ 190mV above VEE, VOH ≥ 300mV below VCC - delivers true rail-to-rail output drive into moderate loads. |
| Capacitive Load Stability | Stable with up to 160pF - eliminates need for isolation resistors when driving ADC inputs or long PCB traces. |
| Common-Mode Range | VEE – 0.2V to VCC + 0.2V - accepts input signals beyond supply rails, simplifying level translation in mixed-supply systems. |
Pinout & Package
MAX4130EUK is housed in a 5-pin SOT23-5 surface-mount package (JEDEC MO-178 compliant), measuring 2.80mm × 2.90mm × 1.30mm, with gull-wing leads and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output node - drives loads directly; rail-to-rail swing supports full dynamic range utilization. |
| 2 | IN− | Inverting input - high-impedance node (500kΩ typical); requires matched source impedance to IN+ to minimize bias-current-induced offset. |
| 3 | IN+ | Noninverting input - same impedance as IN−; polarity switch between NPN/PNP input stages occurs near VCC/2. |
| 4 | VEE | Negative supply terminal - connect to GND for single-supply operation; extends common-mode range 200mV below ground. |
| 5 | VCC | Positive supply terminal - bypass with 0.1µF ceramic + 1µF bulk capacitor to suppress supply noise and ensure stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Enables full-scale signal acquisition and drive in 3V systems without external charge pumps or level shifters. |
| Unity-Gain Stable | Eliminates need for external compensation components, reducing BOM count and layout complexity in follower/buffer designs. |
| No Phase Reversal on Overdrive | Prevents latch-up or erroneous output behavior during input transients exceeding supply rails - critical for sensor fault tolerance. |
| Low Input Bias Current (±160nA max) | Minimizes voltage drop across high-impedance sensor sources (e.g., pH electrodes, piezoelectric elements). |
| 160pF Capacitive-Load Tolerance | Supports direct connection to SAR ADC inputs or long interconnects without added series resistance or peaking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-channel, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift architecture; 0.02µV/°C offset drift vs. MAX4130EUK's ±2µV/°C; 350kHz GBW vs. 10MHz. | Better DC precision but lower bandwidth - suited for ultra-stable sensor bridges, not high-speed data acquisition. | Select OPA333AIDBVR when sub-µV offset drift dominates over speed; avoid when >100kHz signal content exists. |
| AD8605ARTZ-REEL7 | Higher 10MHz GBW and 5V/µs slew rate; 130µA IQ vs. 900µA; no guaranteed 2.7V operation (min 2.7V typical only). | Lower power and faster settling, but not production-validated below 2.7V - risk in brown-out conditions. | Select AD8605ARTZ-REEL7 for battery-constrained apps needing lower IQ; verify 2.7V startup margin in final design. |
Compared with OPA333AIDBVR and AD8605ARTZ-REEL7, the MAX4130EUK uniquely combines guaranteed 2.7V operation, 10MHz bandwidth, rail-to-rail I/O, and industrial temperature range in a space-saving SOT23-5 package-making it optimal for cost-sensitive, high-fidelity portable instrumentation where both speed and low-voltage robustness are mandatory.

FAQ
Does the MAX4130EUK have a shutdown pin?
No, the MAX4130EUK does not include a shutdown function. Unlike the MAX4131 and MAX4133 variants, it has only five pins (OUT, IN−, IN+, VEE, VCC) and no SHDN terminal. Its supply current remains at ~900µA per amplifier under all operating conditions, making it unsuitable for ultra-low-power duty-cycled systems requiring standby modes.
What is the maximum capacitive load the MAX4130EUK can drive stably?
The MAX4130EUK is unity-gain stable with capacitive loads up to 160pF, as confirmed in the AC Electrical Characteristics table and Figure 4 of the datasheet. This allows direct connection to ADC inputs, long PCB traces, or small ceramic filters without adding isolation resistors-reducing component count and preserving signal fidelity.
Is the MAX4130EUK specified for operation below 2.7V?
While the MAX4130EUK's absolute minimum supply voltage is specified as +2.7V, the datasheet notes that the device "typically operates down to 1.8V." However, only parameters at +2.7V to +6.5V are guaranteed across temperature. For production designs requiring reliable sub-2.7V operation, validation under actual conditions is required, as no characterization data is provided below 2.7V.
How does the input stage architecture of the MAX4130EUK affect bias current behavior?
The MAX4130EUK uses complementary NPN/PNP input pairs to achieve rail-to-rail common-mode range. As the input voltage crosses VCC/2, the dominant input stage switches, causing input bias current polarity reversal. To minimize offset error, external source impedances at IN+ and IN− must be closely matched-especially critical in high-impedance sensor interfaces like thermocouples or photodiodes.
What is the guaranteed input offset voltage specification for MAX4130EUK over temperature?
The MAX4130EUK guarantees a maximum input offset voltage of ±3.5mV over the full -40°C to +85°C operating temperature range, as stated in the DC Electrical Characteristics table (Note 2). This is distinct from the ±200µV typical value measured at +25°C and reflects worst-case production spread across temperature and process variation.
