Product details
Overview
The MAX410BCSA-T from Maxim Integrated is a single-channel, precision bipolar operational amplifier optimized for low-noise, high-speed, low-voltage operation. It delivers 2.4nV/√Hz input voltage-noise density at 1kHz, 28MHz unity-gain bandwidth, and 4.5V/µs slew rate while consuming only 2.5mA per amplifier from ±2.4V to ±5V supplies. 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-T datasheet, MAX410BCSA-T pinout, MAX410BCSA-T application, or MAX410BCSA-T equivalent, this page provides verified technical context, package-specific pin mapping, noise-performance tradeoffs, supply-flexibility boundaries, and validated alternative options for precision analog signal conditioning designs.
Technical Context
The MAX410BCSA-T 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 offset voltage and 115dB min open-loop gain. Its architecture omits input current-limiting resistors (unlike many low-noise op amps) to preserve noise performance, relying instead on back-to-back clamp diodes for ±0.1V differential input protection.
It is unity-gain stable and specified across ±2.4V to ±5V dual supplies, supporting low-voltage operation down to ±2.4V with guaranteed 7.3VP-P output swing into 2kΩ. The device exhibits 105–120dB CMRR and 90–103dB PSRR over its full operating temperature range (–40°C to +85°C), enabling robust performance in noisy industrial and measurement environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage Noise Density | 2.4nV/√Hz (max) at 1kHz - enables sub-microvolt signal resolution in high-gain sensor interfaces |
| Unity-Gain Bandwidth | 28MHz - supports wideband applications including audio preamps and frequency synthesizer loops |
| Slew Rate | 4.5V/µs - ensures faithful reproduction of fast transients up to ~1.5MHz full-power bandwidth |
| Supply Current | 2.5mA per amplifier - balances low-noise performance with power efficiency in battery-sensitive systems |
| Input Offset Voltage | ±250µV (max) - allows direct DC-coupled use in precision instrumentation without external trimming |
| CMRR | 105dB (min) at –40°C to +85°C - maintains common-mode rejection under thermal stress in bridge circuits |
| Operating Supply Range | ±2.4V to ±5V - supports flexible rail selection for mixed-signal systems and legacy ±5V infrastructure |
Pinout & Package
The MAX410BCSA-T is housed in an 8-pin SO (Small Outline) package with standard op-amp pinout and RoHS-compliant lead finish. The exposed pad variant (TDFN) is not applicable to this part number; MAX410BCSA-T uses the standard SOIC-8 body without thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (IN–) | Connects to internal nulling network; used with external potentiometer for fine offset adjustment (±450µV range) |
| 2 | Inverting Input (IN–) | Differential input node; high-impedance bipolar junction with 40MΩ common-mode resistance |
| 3 | Non-Inverting Input (IN+) | Differential input node; matched to IN– for optimal CMRR and bias current cancellation |
| 4 | Negative Supply (V–) | Return path for dual-supply operation; must be connected to system V– rail (not GND in single-supply configs) |
| 5 | Null (IN+) | Second offset-null terminal; paired with Pin 1 for symmetric trimming of input-stage mismatch |
| 6 | Output (OUT) | Class-A/B output stage capable of ±3.7V swing into 2kΩ with <1.3µs settling to 0.1% |
| 7 | Positive Supply (V+) | Power rail connection; supports ±2.4V to ±5V operation; PSRR >90dB across full supply range |
| 8 | No Connect (NC) | Internally unconnected; must remain floating - no tie to V+, V–, or ground |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low voltage noise | 2.4nV/√Hz (max) at 1kHz - among lowest for bipolar op amps in SOIC-8 form factor |
| Bipolar input architecture | No input current-limiting resistors - preserves noise floor but requires external protection for >±0.1V differential inputs |
| Wide supply flexibility | Operates from ±2.4V to ±5V - enables compatibility with both modern low-voltage and legacy ±5V systems |
| Unity-gain stable | No external compensation required - simplifies design in voltage-follower and gain-of-one configurations |
| High channel separation | 135dB at 1kHz - critical for multi-amplifier PCB layouts where crosstalk must be minimized |

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 |
|---|---|---|---|
| OPA1611AIDR | FET-input (vs. bipolar); 1.1nV/√Hz noise but higher 1.3pA/√Hz current noise; 2.2mA supply current | Better for high-Z sources (>10kΩ); less suitable for low-source-impedance IR detectors or bridge sensors | Select OPA1611AIDR when source impedance exceeds 2kΩ and voltage noise dominates total noise budget |
| AD8620ARZ | Bipolar input like MAX410BCSA-T; 2.5nV/√Hz noise; 3.5mA supply current; 25MHz GBW; ±100µV max VOS | Lower offset and wider temp range (–40°C to +125°C), but reduced bandwidth limits high-frequency fidelity | Choose AD8620ARZ for ultra-low-offset DC precision where 28MHz bandwidth is not required |
Compared with OPA1611AIDR and AD8620ARZ, the MAX410BCSA-T uniquely balances ultra-low voltage noise, bipolar input linearity, and 28MHz bandwidth in an industry-standard SOIC-8 package - making it optimal for wideband, low-impedance sensor interfaces where both speed and noise matter.

FAQ
What is the maximum differential input voltage the MAX410BCSA-T can tolerate without damage?
The MAX410BCSA-T contains back-to-back clamp diodes that protect against differential input voltages up to ±0.1V. Exceeding this risks forward-biasing the diodes and causing excessive current flow. For higher differential voltages, external current-limiting resistors must be added to restrict input current to ≤20mA, as specified in Absolute Maximum Ratings. This limitation is inherent to its low-noise bipolar architecture, which omits internal current-limiting resistors to preserve noise performance.
Does the MAX410BCSA-T require external compensation for unity-gain stability?
No, the MAX410BCSA-T is internally compensated for unity-gain stability and does not require external capacitors or feedback networks to prevent oscillation. It remains stable driving capacitive loads up to 3900pF in voltage-follower configuration. For loads exceeding 3900pF, a 10Ω isolation resistor in series with the output restores phase margin - a technique validated in Maxim's typical operating characteristics and application circuits.
How does the MAX410BCSA-T perform at supply voltages below ±5V?
The MAX410BCSA-T is fully specified from ±2.4V to ±5V. At ±2.4V, it maintains 2.4nV/√Hz max noise density, 28MHz GBW, and 4.5V/µs slew rate, though output swing reduces to ±3.5V into 2kΩ. Its PSRR remains ≥90dB across this range, and it supports single-supply operation down to +4.8V total (e.g., 0V and +4.8V), with input common-mode range extending to V– +1.5V and V+ –1.5V.
Can the MAX410BCSA-T drive heavy capacitive loads in non-inverting configurations?
Yes - the MAX410BCSA-T is characterized for capacitive-load driving in both inverting and non-inverting configurations. Its % Overshoot vs. Capacitive Load graph confirms stability up to 3900pF at gains of –1V/V and –10V/V. For non-inverting gains ≥+2, stability is maintained with loads ≤1000pF; beyond that, an output isolation resistor (e.g., 10Ω–100Ω) is recommended to preserve phase margin without degrading DC accuracy.
What is the purpose of Pins 1 and 5 (NULL terminals) on the MAX410BCSA-T?
Pins 1 and 5 are dedicated offset-null terminals connected to the input-stage differential pair. When a 20kΩ potentiometer is wired between them with its wiper to V–, it applies opposing currents to balance input transistor mismatches. This circuit provides ±450µV of trim range - sufficient to nullify the full ±250µV max offset voltage over temperature, enabling zero-drift performance in DC-critical applications like bridge amplifiers and precision integrators.
