Product details
Overview
The MAX410BCSA+ 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 integrity at microvolt levels is critical.
For engineers reviewing the MAX410BCSA+ datasheet, MAX410BCSA+ pinout, MAX410BCSA+ application, or MAX410BCSA+ equivalent, this page provides verified specifications, SO-8 package layout, noise-performance context, offset-null capability, and validated alternatives for low-noise analog signal conditioning in precision measurement and sensor interface designs.
Technical Context
The MAX410BCSA+ employs a proprietary bipolar input stage designed to minimize voltage noise without compromising DC accuracy or AC stability - achieving <2.4nV/√Hz at 1kHz while maintaining ±250µV max input offset voltage and 115dB min open-loop gain. Its architecture avoids input current-limiting resistors to preserve noise performance, relying instead on back-to-back clamp diodes for ±0.1V differential input protection.
It supports stable unity-gain operation with 28MHz bandwidth and drives capacitive loads up to 3900pF in voltage-follower configuration. The device is characterized across 0°C to +70°C (indicated by 'C' grade), with guaranteed performance at ±5V supply and full specification down to ±2.4V, enabling flexible low-voltage system integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage Noise Density | 2.4nV/√Hz (max) at 1kHz - enables sub-microvolt signal resolution in narrowband sensor interfaces. |
| Unity-Gain Bandwidth | 28MHz - supports wideband signal acquisition up to ~10MHz with minimal phase error. |
| Slew Rate | 4.5V/µs - ensures faithful reproduction of fast transients in pulse-amplification and active filter stages. |
| Supply Current | 2.5mA per amplifier - balances low-noise performance with power efficiency in battery-sensitive or multi-channel systems. |
| Input Offset Voltage | ±250µV (max) - allows direct DC-coupled use in precision instrumentation without external trimming in many cases. |
| CMRR | 115dB (min) - rejects common-mode interference in bridge-based transducer circuits and noisy industrial environments. |
| Operating Supply Range | ±2.4V to ±5V - supports dual-supply operation from low-voltage rails, including ±3.3V and ±5V logic-compatible systems. |
Pinout & Package
MAX410BCSA+ is housed in an 8-pin SO (Small Outline) package, compliant with JEDEC MS-012, with 1.27mm pitch and gull-wing leads. Thermal pad is not present - unlike TDFN variants, this SO variant has no exposed paddle.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | Offset null adjustment terminal - connects to external potentiometer (e.g., 10kΩ) for fine-tuning input offset voltage. |
| 2 | IN− | Inverting input - high-impedance node for feedback network connection and differential signal reception. |
| 3 | IN+ | Non-inverting input - high-impedance node for reference or sensor signal input; matched to IN− for CMRR optimization. |
| 4 | V− | Negative supply rail - must be connected to system ground or negative bias; ties to exposed paddle in TDFN but not in SO. |
| 5 | OUT | Amplifier output - capable of ±3.6V swing into 2kΩ load from ±5V supplies; drives cables, ADC drivers, or next-stage filters. |
| 6 | NULL | Second offset null terminal - completes the external trim circuit with Pin 1; unused in non-nulling configurations. |
| 7 | V+ | Positive supply rail - accepts +2.4V to +5V relative to V−; decoupling capacitor (0.1µF) required near pin for stability. |
| 8 | N.C. | No connect - internally unconnected; left floating or tied to ground only if required by board-level EMI mitigation (not recommended). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low voltage noise | 2.4nV/√Hz max at 1kHz - enables detection of weak signals in IR photodiode and piezoelectric sensor front-ends. |
| Offset voltage null capability | External trim via Pins 1 & 6 - provides ±450µV adjustment range to eliminate drift-induced errors over temperature. |
| Capacitive-load drive stability | Stable with 3900pF in unity-gain - eliminates need for isolation resistors in many sensor buffer applications. |
| Bipolar input architecture | No input current-limiting resistors - preserves low-noise performance while using back-to-back clamps for ±0.1V differential protection. |
| Wide supply flexibility | Operates from ±2.4V to ±5V - supports mixed-signal systems with 3.3V/5V domains and low-power portable instrumentation. |

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 |
|---|---|---|---|
| OPA211IDBVT | FET-input, 1.1nV/√Hz at 1kHz, 45MHz GBW, 27V/µs SR, ±18V max supply - lower noise but higher supply requirement and cost. | Better for high-source-impedance sensors (>10kΩ); less suitable for ±2.4V–±5V rail-constrained systems. | Select OPA211IDBVT when source resistance exceeds 2kΩ and wider supply headroom is available. |
| ADA4898-1ARZ | Bipolar-input, 1.1nV/√Hz at 1kHz, 65MHz GBW, 47V/µs SR, ±5V to ±12V supply - superior speed/noise trade-off but higher quiescent current (10.5mA). | Preferred for high-speed data acquisition and composite video buffering; overqualified for static sensor conditioning. | Choose ADA4898-1ARZ when >40MHz bandwidth and <1.2nV/√Hz noise are mandatory, and power budget permits. |
Compared with OPA211IDBVT and ADA4898-1ARZ, the MAX410BCSA+ offers the optimal balance of ultra-low noise, low supply voltage operation, and modest power consumption - making it uniquely suited for portable, battery-powered, or multi-channel precision analog front-ends where ±5V rails and sub-3mA per channel are design constraints.

FAQ
What is the maximum input voltage range for MAX410BCSA+?
The MAX410BCSA+ supports a common-mode input voltage range of (V+ + 0.3V) to (V− − 0.3V), with typical operation between ±3.5V when powered from ±5V supplies. At ±2.4V supplies, the usable common-mode range narrows to approximately ±1.5V. This is specified in the Absolute Maximum Ratings and Electrical Characteristics tables of the MAX410BCSA+ datasheet, and confirmed across temperature ranges from 0°C to +70°C.
Does MAX410BCSA+ require external offset nulling in all applications?
No - MAX410BCSA+ has a maximum input offset voltage of ±250µV, which may be acceptable without trimming in many precision DC-coupled applications. However, its dedicated NULL pins (1 and 6) allow external 10kΩ potentiometer adjustment to cancel residual offset, especially critical in long-term, temperature-varying instrumentation setups. The MAX410BCSA+ offset null circuit provides ±450µV correction range, sufficient to zero out drift over the full 0°C to +70°C operating range.
Can MAX410BCSA+ operate from a single 5V supply?
Yes - although optimized for ±2.4V to ±5V dual supplies, the MAX410BCSA+ supports single-supply operation with total supply voltages as low as 4.8V (e.g., 0V and +4.8V). Input common-mode range extends to within 1.5V of each rail, and output swings to within 1.4V of V+ and 1.3V of V− into 2kΩ. Performance at reduced supply is guaranteed by design and PSRR testing, as documented in the MAX410BCSA+ datasheet's "Total Supply Voltage Considerations" section.
What is the thermal performance difference between MAX410BCSA+ and MAX410ETA?
MAX410BCSA+ is rated for 0°C to +70°C operation in an 8-pin SO package with 471mW max power dissipation at +70°C (derating 5.88mW/°C above). MAX410ETA uses an 8-pin TDFN-EP package rated for −40°C to +85°C, with 1482mW max dissipation (derating 18.5mW/°C). The TDFN's exposed paddle (tied to V−) enables significantly better thermal resistance - critical for high-output-drive or high-ambient industrial applications where the MAX410BCSA+ would thermally saturate.
Is MAX410BCSA+ pin-compatible with other MAX41x series op amps?
Yes - MAX410BCSA+ shares identical 8-pin SO pinout with MAX410CPA, MAX410CSA, MAX410EPA, and MAX410ESA. All share the same NULL/IN−/IN+/V−/OUT/NULL/V+/N.C. assignment. However, MAX412 (dual) and MAX414 (quad) use different pin counts (8- and 14-pin respectively) and are not pin-compatible. The MAX410BCSA+ pinout is explicitly shown in the "Pin Configurations" diagram of the MAX410BCSA+ datasheet and matches industry-standard single-op-amp SO layouts.
