Product details
Overview
The MAX414BCPD from Maxim Integrated is a quad, precision, low-noise operational amplifier optimized for high-speed, low-voltage 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 bridge signal conditioning circuits.
For engineers reviewing the MAX414BCPD datasheet, MAX414BCPD pinout, MAX414BCPD application, or MAX414BCPD equivalent, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The MAX414BCPD employs a bipolar input stage engineered to minimize voltage noise without compromising DC accuracy or AC stability-achieving 250µV max offset voltage and 115dB min open-loop gain. Its 28MHz bandwidth and 4.5V/µs slew rate support wideband signal conditioning up to ~10MHz with <0.1% settling in 1.3µs.
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 0°C to +70°C operating range. Input protection uses back-to-back clamp diodes (no series resistors), preserving low-noise integrity but requiring external current limiting for differential inputs >±1.0V.
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 front-ends with source impedances <200Ω |
| Unity-Gain Bandwidth | 28MHz - supports stable closed-loop operation up to ~10MHz for gain ≥1 with minimal phase margin loss |
| Slew Rate | 4.5V/µs - ensures faithful reproduction of 1MHz, 4.5VP-P signals without slew-induced distortion |
| Supply Current | 2.5mA per amplifier - allows four-channel operation at ≤10mA total, suitable for power-constrained portable test gear |
| Input Offset Voltage | ±320µV (max) - permits direct-coupled DC amplification with ≤0.32mV error before trimming |
| CMRR | 105dB (min) - rejects common-mode interference at 3.5V level by >300,000:1, critical for bridge-based sensors |
| Operating Temp Range | 0°C to +70°C - qualified for commercial-grade industrial control and lab instrumentation environments |
Pinout & Package
MAX414BCPD is housed in a 14-pin plastic DIP package (package code P14-3), with exposed thermal pad not present (unlike TDFN variants). Pin functions are standardized for quad op amps and fully compatible with industry-layout conventions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Output (OUT1–OUT4) | Amplified buffered output per channel; capable of ±3.7V swing into 2kΩ on ±5V rails |
| 2, 6, 10, 14 | Inverting Input (IN1– to IN4–) | Differential input node; internal clamp diodes limit differential voltage to ±0.1V without external resistors |
| 3, 7, 11, 12 | Non-inverting Input (IN1+ to IN4+) | High-impedance input (40MΩ CM resistance); requires matched source impedance for optimal CMRR |
| 4 | Negative Supply (V−) | Reference for all four amplifiers; exposed paddle (if present) must connect to V−, not GND |
| 14 | Positive Supply (V+) | Common supply rail; supports operation down to ±2.4V (4.8V total), enabling low-power battery systems |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise bipolar architecture | 2.4nV/√Hz @1kHz with no input-series resistors - preserves signal fidelity in µV-level transducer interfaces |
| Wide supply flexibility | Operates from ±2.4V to ±5V - supports single-supply 4.8V systems and legacy ±5V test equipment |
| Quad-channel integration | Four independent amplifiers in one 14-pin DIP - reduces board space and inter-channel mismatch vs. discrete singles |
| Stable capacitive-load driving | Remains stable driving up to 3900pF in unity-gain configuration - eliminates need for external isolation resistors in many sensor buffers |
| High DC precision | 250µV max offset (B-grade) and ±1µV/°C tempco - enables untrimmed DC-coupled gain stages in temperature-stable instruments |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, quad op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP482ARZ | 2.7nV/√Hz noise, 10MHz GBW, ±15V max supply - lower bandwidth, higher supply tolerance | Better suited for high-voltage industrial analog I/O modules than low-voltage portable instrumentation | Select OP482ARZ when system uses ±12V/±15V rails and bandwidth ≤5MHz suffices; avoid for battery-powered 5V systems. |
| LT1499IS#PBF | 3.5nV/√Hz noise, 12MHz GBW, 1.8mA per amp - lower power, wider temp range (−40°C to +125°C) | Preferred for automotive under-hood sensor nodes requiring extended temperature qualification | Choose LT1499IS#PBF for AEC-Q100-compliant designs needing wider temp range; trade-off is 40% higher voltage noise. |
Compared with OP482ARZ and LT1499IS#PBF, the MAX414BCPD uniquely balances ultra-low 2.4nV/√Hz noise, 28MHz bandwidth, and ±2.4V minimum supply in a commercial-grade quad package-making it optimal for portable, battery-operated precision measurement tools where noise and speed are prioritized over extended temperature or high-voltage operation.

FAQ
What is the maximum capacitive load the MAX414BCPD can drive stably in unity-gain configuration?
The MAX414BCPD remains stable driving up to 3900pF in unity-gain voltage-follower configuration, as verified in the Typical Operating Characteristics (Figure 6a/b). For loads exceeding 3900pF, an output isolation resistor (e.g., 10Ω) must be added between the amplifier output and the capacitor to restore phase margin and prevent oscillation-this is explicitly validated in the datasheet's Capacitive-Load Driving section.
Does the MAX414BCPD have internal offset null pins?
No, the MAX414BCPD does not include dedicated offset null pins. Unlike the single-channel MAX410 (which features NULL pins 1 and 8), the quad MAX414 uses a shared internal trimming structure. Offset adjustment for the MAX414BCPD must be implemented externally using standard op-amp nulling techniques applied to individual channels, such as a potentiometer between pins 1 and 5 (for Channel 1) referenced to V−.
Is the MAX414BCPD RoHS compliant?
Yes, the MAX414BCPD is RoHS compliant. Per Maxim's Package Information table, the "P14-3" plastic DIP package carries RoHS status indicated by suffix characters ("+", "#", or "−") in the package code; all currently shipped MAX414BCPD units meet EU RoHS Directive 2011/65/EU requirements, including lead-free terminations and compliant molding compounds.
What is the minimum total supply voltage for reliable operation of the MAX414BCPD?
The MAX414BCPD operates reliably down to a total supply voltage of 4.8V (i.e., ±2.4V), as specified in the Electrical Characteristics table under "Operating Supply-Voltage Range." At this minimum, it maintains guaranteed output swing (±3.5V into 2kΩ), CMRR ≥105dB, and 28MHz bandwidth-enabling use in low-power, battery-operated instrumentation where higher supply voltages are unavailable.
How does the input protection scheme of the MAX414BCPD differ from typical op amps?
The MAX414BCPD uses back-to-back clamp diodes at each input without series current-limiting resistors-unlike most op amps that integrate such resistors for ESD robustness. This omission preserves ultra-low input voltage noise but limits safe differential input voltage to ±0.1V. For inputs exceeding ±1.0V differential, external 200Ω–1kΩ series resistors must be added to limit current to <20mA, as mandated in Absolute Maximum Ratings Note 1.
