Product details
Overview
MAX4130EUK-T 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 input offset voltage, and rail-to-rail swing into 250Ω loads - enabling high-fidelity analog front-ends in battery-powered data-acquisition systems.
For engineers reviewing the MAX4130EUK-T datasheet, MAX4130EUK-T pinout, MAX4130EUK-T application, or MAX4130EUK-T equivalent, this page provides verified specifications, SOT23-5 package details, real-world use cases in portable instrumentation, and validated alternative op amps with documented functional trade-offs.
Technical Context
The MAX4130EUK-T employs a dual-input-stage architecture (NPN + PNP differential pairs) to achieve rail-to-rail common-mode input range extending 250mV beyond VEE and VCC. Its unity-gain stable design supports direct use in buffer, gain, and filter configurations without external compensation.
It features no phase reversal under overdriven inputs, stable operation with up to 160pF capacitive loads, and operates across +2.7V to +6.5V single supply - with typical functionality down to +1.8V. Input bias current remains below ±160nA over –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 10MHz - enables accurate amplification of signals up to ~1MHz at unity gain, suitable for sensor signal conditioning and anti-aliasing filters. |
| Supply Current per Amplifier | 900µA at +2.7V - supports >100-hour operation on coin-cell batteries in portable instruments. |
| Input Offset Voltage | ±200µV (typ), ±3.5mV (max, –40°C to +85°C) - ensures <0.1% error in 12-bit ADC front-ends with 2.5V reference. |
| Rail-to-Rail I/O Swing | VOL ≤ 20mV above VEE, VOH ≥ VCC – 25mV (RL = 250Ω) - maximizes dynamic range in 3V systems without level-shifting. |
| Common-Mode Input Range | VEE – 0.25V to VCC + 0.25V - accepts inputs from ground to supply rail, simplifying interfacing with unbuffered sensors and DACs. |
| Slew Rate | 4V/µs - supports clean 1VP-P output at 500kHz without distortion, critical for fast-settling data acquisition. |
| Capacitive Load Stability | Stable with 160pF - eliminates need for isolation resistors when driving ADC input capacitance or long PCB traces. |
Pinout & Package
MAX4130EUK-T is housed in a 5-pin SOT23 package (outline U5-1), footprint-compatible with industry-standard 5-lead SC-70/SOT-23 variants. Thermal resistance θJA = 140°C/W; max power dissipation = 571mW at +70°C ambient.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output node - drives 250Ω loads rail-to-rail; high-impedance during shutdown (not applicable to MAX4130). |
| 2 | IN− | Inverting input - differential pair node; protected by 1kΩ series resistors and back-to-back diodes. |
| 3 | IN+ | Noninverting input - differential pair node; same protection as IN−; bias current polarity flips near VCC/2. |
| 4 | VEE | Negative supply terminal - connect to GND for single-supply operation; extends CMVR 250mV below GND. |
| 5 | VCC | Positive supply terminal - accepts +2.7V to +6.5V; bypass with 0.1µF ceramic + 1µF bulk capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends 250mV beyond both supply rails - eliminates level-shifting for 0–3.3V sensor outputs. |
| No phase reversal on overdrive | Prevents latch-up or erroneous output transitions when inputs exceed supply - critical for fault-tolerant monitoring circuits. |
| Unity-gain stable | Operates reliably at AV = 1 without external compensation - reduces BOM count in buffer applications. |
| Low input bias current mismatch | IOS ≤ ±18nA (max) - minimizes offset error from source impedance imbalances in high-Z sensor interfaces. |
| 1.8V minimum operating voltage (typ) | Enables brown-out operation in aging batteries - extends usable life in handheld medical devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail, low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461IDBVR | Lower GBW (6.4MHz), higher ICC (600µA typ), wider offset range (±1.5mV max), SO-5 package only | Less suitable for >500kHz signal paths; better for ultra-low-noise DC-coupled apps where bandwidth isn't critical | Select if cost sensitivity outweighs speed requirement and SO-5 footprint is acceptable. |
| OPA333AIDBVR | Zero-drift architecture, lower offset (±2µV max), higher ICC (17µA), 350kHz GBW, same SOT23-5 package | Ideal for DC-precision apps (e.g., weigh scales); insufficient bandwidth for AC-coupled sensor signals >10kHz | Choose when µV-level offset stability over temperature matters more than 10MHz bandwidth. |
Compared with TLV2461IDBVR and OPA333AIDBVR, MAX4130EUK-T uniquely balances 10MHz bandwidth, rail-to-rail I/O, and sub-1mA quiescent current in SOT23-5 - making it optimal for portable, wideband analog front-ends where speed, power, and space are jointly constrained.

FAQ
What is the operating supply voltage range for MAX4130EUK-T?
The MAX4130EUK-T operates from a single supply of +2.7V to +6.5V, or dual supplies of ±1.35V to ±3.25V. While the specified minimum is +2.7V, it typically functions down to +1.8V - enabling extended battery life in deeply discharged states. This range is confirmed across –40°C to +85°C ambient temperature per the datasheet's DC electrical characteristics table.
Does MAX4130EUK-T include a shutdown feature?
No, MAX4130EUK-T does not include a shutdown function. Shutdown capability is exclusive to the MAX4131/MAX4133 variants (e.g., MAX4131EBT-T), which feature a SHDN pin reducing supply current to 25µA per amplifier. The MAX4130EUK-T has no SHDN pin and draws 900µA continuously when powered - verified in the "Ordering Information" and "DC Electrical Characteristics" sections of the datasheet.
What is the maximum capacitive load the MAX4130EUK-T can drive stably?
The MAX4130EUK-T is unity-gain stable with capacitive loads up to 160pF, as explicitly stated in the "AC Electrical Characteristics" table and confirmed in Figure 4 ("Capacitive-Load Stability") of the datasheet. Driving larger loads requires an isolation resistor (e.g., 39Ω) between output and capacitance to maintain phase margin - a technique validated in Figures 5–7.
Is MAX4130EUK-T pin-compatible with other op amps in the SOT23-5 package?
MAX4130EUK-T follows the standard SOT23-5 pinout (OUT, IN−, IN+, VEE, VCC), matching industry conventions for single op amps. However, pin compatibility with other manufacturers' SOT23-5 op amps is not guaranteed due to differing internal functions (e.g., some include shutdown or enable pins). Always verify pin mapping against the specific alternative's datasheet before substitution.
What is the input offset voltage specification for MAX4130EUK-T over temperature?
The MAX4130EUK-T has a maximum input offset voltage of ±3.5mV over the full –40°C to +85°C operating range, with a typical value of ±200µV at +25°C. Its offset voltage temperature coefficient is ±2µV/°C, meaning drift contributes ≤ ±300µV over the full range - consistent with the "DC Electrical Characteristics" table on page 4 of the datasheet.
