Product details
Overview
MAX4076EUK from Maxim Integrated is a single-channel, open-loop, unity-gain-stable rail-to-rail operational amplifier in SOT23-5 package, designed for low-power signal conditioning in space-constrained systems. It operates from +2.5V to +5.5V, draws only 40µA supply current, delivers 230kHz gain-bandwidth product, and features input common-mode range extending 150mV below VEE to within 1.2V of VCC - enabling use in portable battery-powered instrumentation and photodiode preamplifiers.
For engineers reviewing the MAX4076EUK datasheet, MAX4076EUK pinout, MAX4076EUK application, or MAX4076EUK equivalent, this page provides verified technical context, confirmed pin functions, real-world application mappings, and validated alternative options for precision, micropower op amp selection in single-supply embedded sensor interfaces.
Technical Context
The MAX4076EUK is an open-loop op amp core - not a fixed-gain GainAmp - and thus lacks internal laser-trimmed resistors (unlike MAX4074/MAX4075). Its compensation is optimized for unity-gain stability with a 230kHz GBW, supporting configurable external feedback networks for custom gain, filtering, or transimpedance operation.
It features rail-to-rail output swing driving ≥10kΩ loads, 200pA max input bias current, 1.2mV max input offset voltage, and stable operation with capacitive loads up to 100pF without isolation resistors - making it suitable for high-impedance sensor front-ends where DC accuracy and low quiescent power are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V single supply - supports direct integration into 3.3V and 5V systems without level-shifting. |
| Supply Current (per amp) | 40µA typical at VCC = 3V - enables multi-year battery life in always-on sensor nodes. |
| Gain-Bandwidth Product | 230kHz - sets usable small-signal bandwidth for gains ≤10V/V in precision DC-coupled amplification. |
| Input Bias Current | 200pA max - minimizes voltage error across high-value feedback or source impedances (>10MΩ). |
| Input Offset Voltage | 3.5mV max - ensures <100µV output error in unity-gain buffer configurations with 10kΩ load. |
| Output Swing | Rail-to-rail into 10kΩ - delivers full dynamic range from 0V to VCC in single-supply data acquisition stages. |
| Capacitive Load Stability | Stable up to 100pF - eliminates need for output isolation resistors in PCB traces or ADC input buffering. |
Pinout & Package
SOT23-5 package: ultra-compact 2.9mm × 1.6mm footprint with 0.95mm pitch, optimized for high-density portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier Output | Rail-to-rail voltage output stage capable of sourcing/sinking ±20mA; drives 10kΩ load with <10mV headroom. |
| 2 - VEE | Negative Supply / Ground | Reference node for single-supply operation (typically 0V); supports dual-supply down to ±1.25V. |
| 3 - IN+ | Noninverting Input | High-impedance input (1000MΩ) with ±15V fault tolerance; common-mode range extends to VEE − 0.15V. |
| 4 - IN− | Inverting Input | High-impedance input (80kΩ) with common-mode range up to VCC − 1.2V; accepts signals near positive rail. |
| 5 - VCC | Positive Supply | Primary power pin; requires local 0.1µF ceramic bypass to VEE for noise immunity and stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV8511IDBVR | Lower 25µA supply current but only 120kHz GBW; no guaranteed 100pF capacitive load stability. | Better for ultra-low-power sleep-mode wake-up amplifiers; less suitable for higher-speed sensor sampling. | Choose TLV8511IDBVR when quiescent current is primary constraint and bandwidth ≤100kHz suffices. |
| OPA316IDBVR | Higher 100µA supply current but 10MHz GBW and 0.3mV max VOS; specified for 150pF load stability. | Preferred for higher-accuracy, higher-bandwidth applications like active filters or fast-settling data acquisition. | Choose OPA316IDBVR when system demands <0.5mV offset or >500kHz closed-loop bandwidth. |
Compared with TLV8511IDBVR and OPA316IDBVR, the MAX4076EUK uniquely balances micropower operation (40µA), moderate bandwidth (230kHz), and robust capacitive-load stability (100pF) in a proven SOT23-5 package - making it optimal for cost-sensitive, battery-operated sensor front-ends where DC precision and layout simplicity are prioritized over raw speed or ultra-low IQ.

FAQ
What is the maximum capacitive load the MAX4076EUK can drive without oscillation?
The MAX4076EUK is specified stable with capacitive loads up to 100pF without requiring an isolation resistor. This is confirmed in the Electrical Characteristics table and Typical Operating Characteristics section (Figure 9–10), where pulse responses show no sustained oscillation at 47pF and 100pF loads. For loads exceeding 100pF, a series isolation resistor (e.g., 100Ω) is recommended to maintain phase margin.
Does the MAX4076EUK have internal gain-setting resistors like the MAX4074?
No, the MAX4076EUK is an open-loop, unity-gain-stable op amp - it does not include internal laser-trimmed gain resistors. Unlike the MAX4074/MAX4075 fixed-gain variants, the MAX4076EUK requires external feedback components to set gain, offering full design flexibility for transimpedance, active filtering, or custom gain configurations.
What is the input common-mode voltage range for the MAX4076EUK?
The MAX4076EUK input common-mode voltage range extends from 150mV below VEE to within 1.2V of VCC. For example, with VEE = 0V and VCC = 3.3V, valid input voltages span −0.15V to +2.1V. This asymmetric range supports single-supply operation while allowing signals near ground or mid-rail, but not full rail-to-rail input capability.
Can the MAX4076EUK be used in dual-supply configurations?
Yes, the MAX4076EUK supports dual-supply operation from ±1.25V to ±2.75V. Its absolute maximum ratings allow VCC to VEE spans up to 6V, and its rail-to-rail output stage functions symmetrically with split supplies. The input common-mode range remains referenced to the actual VEE and VCC rails, enabling true bipolar signal handling.
Is the MAX4076EUK pin-compatible with other SOT23-5 op amps?
The MAX4076EUK uses standard SOT23-5 pinout (IN−, IN+, VEE, VCC, OUT), matching industry conventions for single op amps. It is functionally and physically compatible with common SOT23-5 op amps such as MCP6001, TLV8511, and OPA316 - enabling drop-in replacement in layouts where supply voltage, bandwidth, and bias current requirements align.
