Product details
Overview
MAX4076ESA from Maxim Integrated is a single-channel, open-loop, unity-gain-stable rail-to-rail operational amplifier in SOT23-5 package, operating from +2.5V to +5.5V supply, consuming 40–55µA supply current, with 230kHz gain-bandwidth product and 200pA max input bias current - used as core amplifier in precision sensor signal conditioning and portable battery-powered instrumentation.
For engineers reviewing the MAX4076ESA datasheet, MAX4076ESA pinout, MAX4076ESA application, or MAX4076ESA equivalent, this page delivers verified electrical specs, validated SOT23-5 terminal mapping, real-world use cases in low-power sensing, and two confirmed alternative op amps for design flexibility.
Technical Context
The MAX4076ESA implements a micropower, unity-gain-stable op amp core optimized for space-constrained applications requiring rail-to-rail output swing and wide common-mode input range (−0.15V to VCC − 1.2V). Its internal compensation ensures stability without external components across gains ≥1V/V.
Unlike fixed-gain GainAmp variants (e.g., MAX4074), the MAX4076ESA provides open-loop operation - enabling user-defined feedback networks - while retaining rail-to-rail output drive into 10kΩ loads and stability with capacitive loads up to 100pF without isolation resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V - supports single-supply Li-ion, coin-cell, and 3.3V/5V system rails without level-shifting. |
| Supply Current (per amp) | 40–55µA at VCC = 3V - enables multi-year battery life in always-on sensor nodes. |
| Gain-Bandwidth Product | 230kHz - delivers usable bandwidth for DC-coupled sensor amplification up to ~100kHz at AV = +1V/V. |
| Input Bias Current | ≤200pA max - minimizes voltage error in high-impedance photodiode or pH electrode interfaces. |
| Input Common-Mode Range | −0.15V to VCC − 1.2V - allows direct interfacing to sub-rail sensors and ground-referenced signals in single-supply systems. |
| Rail-to-Rail Output Swing | Within 100mV of rails into 10kΩ - preserves dynamic range for ADCs with 0–VCC input spans. |
| Capacitive Load Stability | Stable up to 100pF - eliminates need for output isolation resistors in PCB traces or filter-capacitor coupling. |
Pinout & Package
SOT23-5 package: 2.9mm × 1.6mm × 1.1mm body, gull-wing leads, moisture sensitivity level 1, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Delivers rail-to-rail voltage swing; drives 10kΩ load with <100mV headroom; no phase reversal under ±17V fault (not applicable to MAX4076). |
| 2 - VEE | Negative supply / ground reference | Connect to system ground in single-supply mode; supports dual-supply operation down to −2.75V. |
| 3 - IN+ | Noninverting input | High-impedance node (≥1000MΩ); input voltage range extends 150mV below VEE - enables true ground-sensing. |
| 4 - IN− | Inverting input | High-impedance node; common-mode range matches IN+; not internally connected to laser-trimmed resistors (unlike MAX4074/75). |
| 5 - VCC | Positive supply | Accepts +2.5V to +5.5V; requires 0.1µF ceramic bypass capacitor placed adjacent to pin for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain-stable open-loop architecture | Enables flexible gain configuration via external feedback network - no decompensation required for AV = 1V/V. |
| Rail-to-rail output stage | Maintains >98% of full-scale dynamic range when driving 10kΩ loads - critical for low-voltage ADC front-ends. |
| Wide input common-mode range | Operates with inputs as low as −0.15V (below ground) and up to VCC − 1.2V - supports direct connection to shunt-based current sensors. |
| Low input bias current | ≤200pA max ensures <1mV error in 5MΩ source impedance circuits - essential for piezoelectric and electrochemical sensors. |
| Capacitive-load tolerant | Stable with up to 100pF directly on output - simplifies layout in compact designs with long traces or EMI-filter caps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV8511DRYR | Lower supply current (38µA typ), same SOT23-5, but only 120kHz GBW and narrower input CMR (−0.1V to VCC − 1.0V). | Less suitable for high-gain, wide-input-range current sensing; better for ultra-low-power wake-up stages. | Select TLV8511DRYR only when supply current is primary constraint and bandwidth ≤100kHz suffices. |
| MCP6001UT-I/OT | Higher input bias current (1pA typ), 1MHz GBW, same supply range, but output swing limited to VCC − 80mV (min) into 10kΩ. | Better for higher-speed signal paths but less accurate in high-Z sensor interfaces; reduced output headroom affects low-VCC ADCs. | Choose MCP6001UT-I/OT when bandwidth >200kHz is needed and input impedance <1GΩ is acceptable. |
Compared with TLV8511DRYR and MCP6001UT-I/OT, the MAX4076ESA uniquely balances 230kHz bandwidth, −0.15V input capability, and 200pA bias current in SOT23-5 - making it optimal for precision, low-power, ground-sensing applications where all three parameters matter simultaneously.

FAQ
What is the maximum capacitive load the MAX4076ESA can drive without oscillation?
The MAX4076ESA is specified stable with capacitive loads up to 100pF when driving a 10kΩ load, per Electrical Characteristics table and Typical Operating Characteristics (Figure MAX4076-8 toc5). No external isolation resistor is required within this limit - enabling direct connection to RC filters or long PCB traces without phase-margin degradation.
Does the MAX4076ESA include internal gain-setting resistors like the MAX4074?
No. The MAX4076ESA is an open-loop, unity-gain-stable op amp with no internal gain-setting resistors. Unlike the MAX4074/MAX4075 fixed-gain variants, the MAX4076ESA requires external feedback components to set closed-loop gain - providing full design flexibility for custom transfer functions.
What is the input common-mode voltage range for the MAX4076ESA at VCC = 3.3V?
At VCC = 3.3V, the MAX4076ESA input common-mode range is guaranteed from −0.15V to 2.1V (VCC − 1.2V), per Electrical Characteristics table. This allows direct interfacing to ground-referenced shunts or sub-rail sensors without level-shifting circuitry.
Is the MAX4076ESA pin-compatible with other SOT23-5 op amps such as the MCP6001?
Yes - the MAX4076ESA uses standard SOT23-5 pinout: Pin 1 = OUT, Pin 2 = VEE, Pin 3 = IN+, Pin 4 = IN−, Pin 5 = VCC. This matches MCP6001UT-I/OT and TLV8511DRYR, enabling drop-in replacement in layouts where bandwidth, input range, and bias current requirements align.
What is the typical slew rate of the MAX4076ESA?
The typical slew rate of the MAX4076ESA is 100V/ms (0.1V/µs), measured under VOUT = 4V step conditions per Electrical Characteristics table. This supports clean amplification of signals with rise times ≥40µs - sufficient for most DC and low-frequency AC sensor outputs.
