Product details
Overview
The MAX410BCPA from Maxim Integrated is a single, precision, low-noise bipolar operational amplifier optimized for high-speed, low-voltage 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 where signal fidelity and noise floor are critical.
For engineers reviewing the MAX410BCPA datasheet, MAX410BCPA pinout, MAX410BCPA application, or MAX410BCPA equivalent, key selection criteria include its guaranteed 2.4nV/√Hz max noise at 1kHz, ±250µV max offset voltage (B-grade), 8-pin PDIP package compatibility, and operation down to ±2.4V supply - all validated across 0°C to +70°C.
Technical Context
The MAX410BCPA employs a proprietary bipolar input stage designed to minimize voltage noise without compromising DC accuracy or AC stability. Its 28MHz gain-bandwidth product and 4.5V/µs slew rate support wideband closed-loop configurations up to 10MHz with minimal distortion, while the absence of input current-limiting resistors preserves low-noise performance.
It features rail-to-rail output swing capability (±3.6V into 2kΩ from ±5V), 115dB minimum open-loop voltage gain, and 105dB minimum CMRR over temperature - enabling high-precision differential sensing in bridge signal conditioning and low-level audio preamplification circuits.
Key Specifications

| Slew Rate | 4.5V/µs - enables accurate reproduction of fast transients in measurement systems |
| Supply Current | 2.5mA per amplifier - enables low-power, multi-channel analog front-ends without thermal derating |
| Input Offset Voltage | ±250µV max (B-grade) - ensures <0.01% error in 25mV full-scale instrumentation amplifier designs |
| Common-Mode Rejection Ratio | 105dB min over 0°C to +70°C - rejects interference in unshielded bridge or thermocouple circuits |
| Operating Supply Range | ±2.4V to ±5.25V - allows direct interface with legacy ±3V or ±5V logic and data converters |
Pinout & Package
MAX410BCPA is housed in an 8-pin plastic DIP (dual in-line package) with standard op-amp pinout compatible with industry-wide PCB footprints and socketing solutions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Null (Offset Adjust) | Connects to external potentiometer for trimming input offset voltage; required for <100µV system-level offset |
| 2 | Inverting Input (IN−) | Differential input node; high-impedance bipolar junction with 40MΩ common-mode resistance |
| 3 | Noninverting Input (IN+) | Differential input node; matched to Pin 2 for optimal CMRR and noise rejection |
| 4 | V− | Negative supply rail; must be connected to system ground reference when using single-supply configuration |
| 5 | Null (Offset Adjust) | Second terminal of offset null circuit; used with Pin 1 to form adjustable voltage divider |
| 6 | Output (OUT) | Class-A/B output stage capable of ±3.6V swing into 2kΩ load from ±5V supplies |
| 7 | V+ | Positive supply rail; decoupling capacitor (0.1µF) required within 1cm for stability |
| 8 | No Connect (N.C.) | Internally unused; must remain floating - no external connection permitted |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low voltage noise | 2.4nV/√Hz max at 1kHz - enables detection of sub-µV signals in IR photodiode and strain gauge amplifiers |
| B-grade precision | ±250µV max input offset - eliminates need for external auto-zero circuitry in portable instrumentation |
| Wide supply flexibility | Operates from ±2.4V to ±5.25V - supports battery-powered designs and mixed-voltage systems |

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 | Lower noise (1.1nV/√Hz), but higher supply current (3.6mA); JFET input vs. bipolar | Superior for ultra-low-noise audio; less suitable for low-impedance source matching | Select OPA211IDR when source impedance >10kΩ and lowest possible noise dominates; retain MAX410BCPA for <1kΩ sources or ±2.4V operation |
| AD8675ARZ | Zero-drift architecture; 2.8nV/√Hz noise; rail-to-rail output; higher CMRR (130dB) | Better DC stability over temperature; limited to ±5V max supply; no offset null pins | Choose AD8675ARZ for high-precision DC-coupled systems requiring <1µV/°C drift; use MAX410BCPA when offset trim or wider supply range is needed |
Compared with OPA211IDR and AD8675ARZ, the MAX410BCPA uniquely balances ultra-low voltage noise, bipolar input optimization for low-source-impedance sensors, ±2.4V supply capability, and user-adjustable offset - making it irreplaceable in legacy industrial bridge and IR detector designs requiring proven reliability and DIP packaging.

FAQ
What is the maximum input voltage range for the MAX410BCPA?
The MAX410BCPA has a common-mode input voltage range of ±3.5V (minimum) to +3.7V/–3.8V (typical) when operated from ±5V supplies. This means inputs must stay within 0.3V of either supply rail - i.e., between V− + 0.3V and V+ − 0.3V - to avoid forward-biasing internal protection diodes. Exceeding this range risks latch-up or increased input current noise. The MAX410BCPA datasheet specifies absolute maximum common-mode voltage as (V+ + 0.3V) to (V− − 0.3V).
Does the MAX410BCPA require external compensation for unity-gain stability?
No, the MAX410BCPA is internally compensated for unity-gain stability and requires no external capacitors or resistors to maintain phase margin. Its 28MHz gain-bandwidth product and 4.5V/µs slew rate are fully characterized under unity-gain conditions with a 10kΩ || 20pF load. This eliminates design risk in buffer and follower configurations - a key advantage over decompensated op amps that mandate minimum gain for stability.
Can the MAX410BCPA operate from a single 5V supply?
Yes, the MAX410BCPA supports single-supply operation with total supply voltages as low as 4.8V (e.g., 0V to +4.8V). However, its input common-mode and output swing ranges are asymmetric: minimum input voltage is V− + 1.5V, and output swing is limited to V+ − 1.4V and V− + 1.3V into 2kΩ. For true rail-to-rail input/output, a different amplifier family is recommended; the MAX410BCPA is optimized for split-supply ±2.4V to ±5V use.
What is the purpose of Pins 1 and 5 on the MAX410BCPA?
Pins 1 and 5 on the MAX410BCPA are dedicated offset-null terminals. They connect to the ends of an external 10kΩ potentiometer (wiper to V−), allowing manual adjustment of input offset voltage to ≤±10µV. This circuit is essential for achieving sub-0.001% gain error in precision instrumentation amplifier topologies. Unlike many op amps, the MAX410BCPA provides dedicated null pins rather than relying on internal trimming alone - a feature retained from its industrial-grade heritage.
How does the MAX410BCPA compare to the standard MAX410CPA grade?
The MAX410BCPA is the B-grade version of the MAX410, featuring tighter specifications than the standard C-grade MAX410CPA: ±250µV max input offset voltage (vs. ±350µV), ≤2.4nV/√Hz max input voltage-noise density (vs. ≤4.0nV/√Hz), and guaranteed 115dB min voltage gain (vs. 110dB). Both share identical pinout, package, and temperature range (0°C to +70°C), but the B-grade is selected for applications demanding higher DC precision and lower noise floor - such as calibrated test equipment and medical diagnostics.
