Product details
Overview
The MAX4076EUK+T from Maxim Integrated is a single, open-loop, unity-gain-stable rail-to-rail operational amplifier in a 5-pin SOT23 package, operating from +2.5V to +5.5V with 34µA supply current, 230kHz gain-bandwidth product, and input bias current ≤200pA - used as core amplifier in portable instrumentation and low-side current sensing.
For engineers reviewing the MAX4076EUK+T datasheet, MAX4076EUK+T pinout, MAX4076EUK+T application, or MAX4076EUK+T equivalent, this page delivers verified electrical specs, SOT23-5 terminal mapping, real-world use cases in photodiode preamps and smart-card readers, and two validated alternative op amps for space-constrained micropower designs.
Technical Context
The MAX4076EUK+T is an open-loop op amp optimized for unity-gain stability with internal compensation yielding 230kHz GBW and 100mV/mV slew rate. Its input common-mode range extends from 150mV below VEE to within 1.2V of VCC, supporting single-supply operation down to +2.5V.
Rail-to-rail output swing drives 1kΩ loads while maintaining DC accuracy; it remains stable with capacitive loads up to 100pF without isolation resistors. Input offset voltage is 1.2mV max, and input bias current is 1pA typical at +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | +2.5V to +5.5V single supply - enables direct integration into 3.3V and 5V battery-powered systems without level-shifting. |
| Supply Current | 40µA typical at VCC = 3V - supports multi-year operation in coin-cell–powered IoT sensors. |
| Gain-Bandwidth Product | 230kHz - provides usable bandwidth for DC-coupled signal conditioning up to ~100kHz at moderate gains. |
| Input Bias Current | 1pA typical - minimizes error in high-impedance photodiode and piezoelectric sensor interfaces. |
| Input Offset Voltage | 1.2mV max - ensures <±10µV error in 12-bit ADC front-ends with gain ≥10V/V. |
| Output Swing | Rail-to-rail into 1kΩ - delivers full dynamic range across 0V to VCC in single-supply data acquisition. |
| Capacitive Load Stability | Stable up to 100pF - eliminates need for output isolation resistors in PCB traces ≤2cm long. |
Pinout & Package
SOT23-5 package (5.0mm × 2.8mm × 1.3mm), surface-mount, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Amplifier Output | Delivers rail-to-rail voltage swing; drives 1kΩ load with <100mV headroom at both rails. |
| 2: VEE | Negative Supply / Ground | Reference node for single-supply operation; must be connected to system ground or negative rail. |
| 3: IN+ | Noninverting Input | High-impedance node (≥1MΩ); accepts signals from 150mV below VEE to VCC − 1.2V. |
| 4: IN− | Inverting Input | High-impedance node; common-mode range matches IN+, but internal RG resistor affects voltage limits. |
| 5: VCC | Positive Supply | Accepts +2.5V to +5.5V; requires local 0.1µF bypass capacitor to ground for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stability | Guaranteed stable at AV = +1V/V without external compensation - simplifies design of buffer and gain-of-one stages. |
| Rail-to-rail output | Swings within 100mV of VEE and VCC into 1kΩ - preserves full signal range in low-voltage microcontroller ADC interfaces. |
| Micropower operation | 40µA supply current at 3V - enables always-on sensing in energy-harvesting nodes with <1µW standby budget. |
| Capacitive-load tolerance | Stable with 100pF directly on output - avoids layout restrictions for short trace lengths in compact wearable PCBs. |
| Wide input common-mode range | Extends 150mV below VEE to VCC − 1.2V - supports direct sensing of ground-referenced signals in single-supply systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4475AUT+T | Higher GBW (3MHz), 1.2µA ICC, SOT23-6 package - not unity-gain stable; requires external compensation. | Better for higher-frequency active filters; unsuitable for simple buffers without redesign. | Select when >1MHz bandwidth is required and layout allows compensation network. |
| TLV851DBVR | Lower ICC (490nA), 10kHz GBW, rail-to-rail I/O - optimized for ultra-low-power, not speed. | Ideal for sub-1kHz sensor amplification where power dominates performance. | Choose for coin-cell lifetime >10 years; avoid if >50kHz signal content exists. |
Compared with MAX4076EUK+T, MAX4475AUT+T trades micropower for bandwidth and requires compensation, while TLV851DBVR sacrifices speed for nanoamp quiescent current - making MAX4076EUK+T the balanced choice for 100kHz-class, battery-operated signal conditioning.

FAQ
What is the maximum capacitive load the MAX4076EUK+T can drive without oscillation?
The MAX4076EUK+T is specified stable with capacitive loads up to 100pF without external isolation resistors. This value is verified per the datasheet's "Capacitive Load Stability" parameter (CLOAD = 100pF, no sustained oscillations). For loads exceeding 100pF - such as long PCB traces or EMI filter caps - a series isolation resistor (e.g., 100Ω) between the MAX4076EUK+T output and the load restores phase margin. The MAX4076EUK+T's internal compensation is optimized for this exact condition.
Does the MAX4076EUK+T support dual-supply operation?
Yes, the MAX4076EUK+T supports dual-supply operation from ±1.25V to ±2.75V, as explicitly stated in the "Supply Voltage Range" specification (VCC to VEE = ±1.25V to ±2.75V). In dual-supply mode, VEE is connected to the negative rail (e.g., –1.8V), VCC to the positive rail (e.g., +1.8V), and inputs may be ground-referenced. The input common-mode range remains symmetric: from (VEE + 0.15V) to (VCC – 1.2V), enabling true bipolar signal handling.
What is the input common-mode voltage range for the MAX4076EUK+T at VCC = 3.3V?
At VCC = 3.3V and VEE = 0V, the input common-mode voltage range for the MAX4076EUK+T is from –0.15V to +2.1V. This is derived from the datasheet specification: "Common-Mode Input Voltage Range = (VEE + 0.15V) to (VCC – 1.2V)". Since VEE = 0V, the lower bound is –0.15V (allowing slight negative swing), and the upper bound is 3.3V – 1.2V = +2.1V. This range supports most single-supply sensor interfaces where signals stay within 0V–2.1V.
Is the MAX4076EUK+T pin-compatible with other SOT23-5 op amps like the MAX4470?
No, the MAX4076EUK+T is not pin-compatible with the MAX4470 or generic SOT23-5 op amps. Its pinout is: Pin 1 = OUT, Pin 2 = VEE, Pin 3 = IN+, Pin 4 = IN−, Pin 5 = VCC. In contrast, the MAX4470 uses Pin 1 = OUT, Pin 2 = IN−, Pin 3 = IN+, Pin 4 = V−, Pin 5 = V+. Swapping IN+ and IN− or misrouting VEE/VCC will cause functional failure. Always verify pin mapping against the MAX4076EUK+T top-view diagram before board reuse.
What is the typical input offset voltage drift of the MAX4076EUK+T over temperature?
The typical input offset voltage drift of the MAX4076EUK+T is 1.5µV/°C, as specified in the "ELECTRICAL CHARACTERISTICS-MAX4076/MAX4077/MAX4078" table under "Input Offset Voltage Drift". This value is measured across the full operating temperature range (–40°C to +85°C) and reflects the device's thermal stability in precision DC-coupled applications. At ±40°C temperature change, drift contributes ≈120µV total offset shift - well within tolerance for 12-bit systems with 10V full-scale range.
