Product details
Overview
The MAX410EPA from Maxim Integrated is a single, precision, low-noise bipolar operational amplifier designed for high-speed, low-voltage signal conditioning in instrumentation and measurement systems. It delivers 2.4nV/√Hz input voltage-noise density at 1kHz, 28MHz unity-gain bandwidth, and 4.5V/µs slew rate while operating from ±2.4V to ±5V supplies and consuming only 2.5mA per amplifier. It is used in ultra-low-noise instrumentation amplifiers and infrared detector front-ends.
For engineers reviewing the MAX410EPA datasheet, MAX410EPA pinout, MAX410EPA application, or MAX410EPA equivalent, this page provides verified electrical specifications, temperature-rated performance (–40°C to +85°C), DIP-8 package details, noise-optimized design context, and validated alternative op amps for low-noise, wideband analog signal chains.
Technical Context
The MAX410EPA employs a proprietary bipolar input stage optimized for minimum voltage noise without sacrificing DC accuracy or AC stability - achieving <2.4nV/√Hz at 1kHz while maintaining ±250µV max offset voltage and 115dB min open-loop gain. Its 28MHz bandwidth and 4.5V/µs slew rate support stable unity-gain operation in wideband transimpedance and active filter configurations.
Designed for ±2.4V to ±5V dual-supply operation, it guarantees 7.3VP-P output swing into 2kΩ and maintains CMRR ≥105dB and PSRR ≥90dB across its full –40°C to +85°C industrial temperature range. Input protection uses back-to-back clamp diodes without series resistors to preserve noise performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage Noise Density | 2.4nV/√Hz (max) at 1kHz - enables sub-µV RMS noise in precision sensor interfaces with source impedances <200Ω |
| Unity-Gain Bandwidth | 28MHz - supports stable wideband amplification up to ~10MHz closed-loop gain-bandwidth tradeoffs |
| Slew Rate | 4.5V/µs - ensures faithful reproduction of fast-rising signals (e.g., pulse conditioning) without distortion |
| Supply Current | 2.5mA per amplifier - balances low-noise performance with power efficiency in battery- or thermally constrained designs |
| Input Offset Voltage | ±400µV (max) over –40°C to +85°C - supports DC-coupled, high-gain stages without excessive drift-induced error |
| Common-Mode Rejection | 105dB (min) - rejects interference in bridge-based sensor circuits with asymmetric common-mode shifts |
| Operating Temperature | –40°C to +85°C - qualified for industrial and automotive under-hood environments requiring extended thermal reliability |
Pinout & Package
MAX410EPA is housed in an 8-pin plastic DIP package (package code P8-1), with pin 1 designated by notch or dot marking. The device follows industry-standard single op amp pinout: pins 2 (inverting input), 3 (non-inverting input), 4 (V−), 7 (V+), and 6 (output). Pins 1 and 5 are null-offset terminals; pin 8 is unused (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | Offset null adjustment terminal - connects to potentiometer wiper for manual VOS trimming (±450µV range) |
| 2 | IN− | Inverting input - accepts feedback network connection; high-impedance node sensitive to layout-induced noise |
| 3 | IN+ | Non-inverting input - reference point for differential sensing; requires matched trace impedance for CMRR optimization |
| 4 | V− | Negative supply rail - must be decoupled locally with 0.1µF ceramic capacitor to minimize supply-induced noise coupling |
| 5 | NULL | Offset null adjustment terminal - connects to potentiometer end for manual VOS trimming (±450µV range) |
| 6 | OUT | Amplifier output - capable of driving 2kΩ loads to ±3.6V; requires isolation resistor when driving >3900pF capacitive loads |
| 7 | V+ | Positive supply rail - must be decoupled locally with 0.1µF ceramic capacitor; supports ±2.4V to ±5V operation |
| 8 | N.C. | No connect - electrically isolated; no internal connection or function |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low voltage noise | 2.4nV/√Hz (max) at 1kHz - sets benchmark for bipolar op amps in low-source-impedance applications (<200Ω) |
| Wide supply flexibility | ±2.4V to ±5V operation - enables compatibility with legacy ±3V, ±5V, and modern low-voltage rails without level-shifting |
| Unity-gain stable | 28MHz GBW with no external compensation - simplifies design of high-fidelity buffers and active filters |
| Industrial temperature grade | –40°C to +85°C guaranteed performance - eliminates derating concerns in uncontrolled ambient deployments |
| Optimized input protection | Back-to-back clamp diodes without series resistors - preserves input noise floor while limiting differential input to ±0.1V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | FET-input (not bipolar); 1.1nV/√Hz noise but higher 1/f corner (~10Hz vs. 90Hz); 4.3mA supply current | Better for ultra-low bias current applications (>1GΩ source impedance); less optimal for low-Z sensor interfaces | Select OPA211IDR when input bias current <1pA is critical and source impedance exceeds 10kΩ |
| ADA4898-1ARZ | Bipolar input; 1.0nV/√Hz noise; 1GHz GBW; ±12V max supply; 12.5mA supply current | Higher speed/power - suited for RF/IF gain blocks, not low-power portable instrumentation | Choose ADA4898-1ARZ only when >100MHz bandwidth and sub-1nV/√Hz noise justify 5× higher supply current |
Compared with OPA211IDR and ADA4898-1ARZ, the MAX410EPA uniquely balances sub-2.5nV/√Hz noise, 28MHz bandwidth, 2.5mA supply current, and ±2.4V–±5V operation - making it the optimal choice for portable, battery-aware, low-source-impedance precision analog front-ends.

FAQ
What is the maximum supply voltage rating for the MAX410EPA?
The MAX410EPA has an absolute maximum supply voltage rating of ±6V (12V total), but its specified operating range is ±2.4V to ±5V. Operation at ±5V delivers full performance including 7.3VP-P output swing into 2kΩ. Exceeding ±5V may degrade noise, offset, or reliability and is not guaranteed by specification.
Does the MAX410EPA require external compensation for unity-gain stability?
No, the MAX410EPA is internally compensated for unity-gain stability. Its 28MHz gain-bandwidth product and 4.5V/µs slew rate are fully characterized and guaranteed under unity-gain conditions with standard 10kΩ || 20pF load. No external capacitors or resistors are needed for stable operation at AV = +1 or –1.
How is the offset voltage adjusted on the MAX410EPA?
The MAX410EPA provides two dedicated null terminals (pins 1 and 5) for manual offset trimming. A 10kΩ potentiometer is connected between pins 1 and 5, with its wiper tied to V−. This configuration provides approximately ±450µV of adjustment range - sufficient to nullify the ±400µV max VOS over temperature.
Can the MAX410EPA drive large capacitive loads directly?
The MAX410EPA remains stable driving up to 3900pF in unity-gain follower configuration. For loads exceeding 3900pF (e.g., 0.015µF), an isolation resistor (e.g., 10Ω) must be placed in series with the output. Without this resistor, phase margin erosion leads to overshoot or oscillation - confirmed in Figure 7b of the datasheet.
What is the input protection scheme used in the MAX410EPA?
The MAX410EPA uses back-to-back silicon diodes between IN+ and IN− for differential input protection, clamping voltages to ±0.1V. Unlike many op amps, it omits series current-limiting resistors to preserve its 2.4nV/√Hz noise performance. Users must externally limit differential input current to <20mA if voltages exceed ±1.0V.
