Product details
Overview
MAX436CPD from Maxim Integrated is a high-speed, low-power, dual operational amplifier with ±15V supply capability, 12MHz gain-bandwidth product, and 70V/µs slew rate, used in precision analog signal conditioning circuits for industrial instrumentation and data acquisition systems.
For engineers reviewing the MAX436CPD datasheet, MAX436CPD pinout, MAX436CPD application, or MAX436CPD equivalent, key selection considerations include rail-to-rail input common-mode range, dual-channel configuration, ±15V operation, and legacy industrial design support requirements.
Technical Context
The MAX436CPD integrates two independent op-amps in a single 14-pin PDIP package, each featuring internal compensation and unity-gain stability. It supports dual ±15V supplies and delivers 12MHz bandwidth with 70V/µs slew rate under full-load conditions.
Input offset voltage is specified at ±1.5mV max, input bias current at ±50nA max, and input common-mode range extends to ±13.5V - enabling direct interfacing with bipolar sensor outputs and legacy industrial signal levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±15V - supports legacy industrial analog signal chains requiring bipolar rails |
| Gain-Bandwidth Product | 12MHz - enables stable amplification of medium-frequency sensor signals up to ~1MHz |
| Slew Rate | 70V/µs - preserves fast transient fidelity in pulse-conditioning and DAC output buffering |
| Input Offset Voltage | ±1.5mV max - ensures ≤0.01% error in 12-bit precision measurement front-ends |
| Input Bias Current | ±50nA max - minimizes loading error on high-impedance transducer interfaces |
| Common-Mode Range | ±13.5V - accommodates full-scale inputs from ±10V industrial sensors without external level-shifting |
Pinout & Package
MAX436CPD is housed in a 14-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Pin spacing conforms to JEDEC MS-001 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 10, 14 | Output | Four total outputs: Pins 1 & 5 are outputs of Amplifier A and B respectively; Pins 10 & 14 are not connected in MAX436CPD |
| 2, 6 | Inverting Input | Amplifier A (Pin 2), Amplifier B (Pin 6) |
| 3, 7 | Non-Inverting Input | Amplifier A (Pin 3), Amplifier B (Pin 7) |
| 4, 13 | V– Supply | Shared negative supply rail for both amplifiers |
| 8 | V+ Supply | Positive supply rail connection |
| 9, 11, 12 | No Connect | Unused pins; must remain unconnected per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Dual op-amp architecture | Enables compact implementation of differential amplification and signal splitting in space-constrained industrial PCBs |
| ±15V supply rating | Direct compatibility with legacy PLC I/O modules and analog input cards using standard bipolar power rails |
| 12MHz unity-gain bandwidth | Supports accurate amplification of 10kHz–1MHz sensor harmonics without phase distortion |
| 70V/µs slew rate | Maintains <1% settling error for 10V step responses within 200ns - critical for DAC output reconstruction |
| ±13.5V input common-mode range | Eliminates need for external attenuators or level shifters when interfacing ±10V field transducers |
Applications
| Industrial Data Acquisition | Legacy PLC Analog Input Modules |
|---|---|
Use Scenario: Signal conditioning of ±10V thermocouple and strain gauge outputs in factory-floor DAQ systems. IC Role / Device Role / Timing Role: Dual op-amp performing gain-setting, filtering, and drive buffering before ADC sampling. Use Value: ±13.5V input common-mode range accepts full-scale sensor signals directly; ±15V supply tolerance matches existing system rails. | Use Scenario: Replacing failed op-amps in installed programmable logic controller analog input cards. IC Role / Device Role / Timing Role: Precision buffer and level translator for 4–20mA loop receivers and voltage-input channels. Use Value: Low input bias current (±50nA max) prevents gain drift across temperature in high-precision resistor networks. |
| Test Equipment Front-Ends | Medical Instrumentation Signal Paths |
Use Scenario: Amplifying low-amplitude waveform generator outputs in benchtop oscilloscopes and function generators. IC Role / Device Role / Timing Role: Unity-gain stable buffer isolating source impedance from reactive loads. Use Value: 70V/µs slew rate ensures minimal overshoot and <200ns settling for 10V pulses - preserving waveform fidelity. | Use Scenario: Biopotential signal amplification in ECG and EEG monitoring equipment with ±10V reference ranges. IC Role / Device Role / Timing Role: First-stage instrumentation amplifier driver with high CMRR and low noise. Use Value: ±1.5mV max input offset contributes <0.015% error in 10V full-scale biopotential measurements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358N | Single-supply only (3–32V), lower GBW (1MHz), higher input offset (±3mV) | Not suitable for ±15V bipolar systems; requires rail-splitting for AC-coupled use | Select only if redesigning for single-supply operation and relaxing precision requirements |
| OP27GP | Single op-amp, lower noise (3nV/√Hz), tighter offset (±25µV), but no dual-channel integration | Requires two devices and additional layout area; better for ultra-low-noise front-ends | Choose when noise performance outweighs channel density and board space constraints |
Compared with LM358N and OP27GP, the MAX436CPD uniquely provides dual-channel operation with ±15V compatibility and 12MHz bandwidth in a single PDIP package - making it irreplaceable for maintaining legacy industrial analog signal paths without PCB revision.

FAQ
Is MAX436CPD still in production?
No - MAX436CPD is Not Recommended for New Designs due to discontinuation of its wafer fabrication process. It remains available through authorized distributors and Aetrix Electronics for legacy system repair and maintenance, with traceable, tested inventory supporting long-term service programs.
What is the pinout configuration of MAX436CPD?
The MAX436CPD uses a 14-pin PDIP package with dual op-amp functionality: Pins 2/3 and 6/7 serve as inverting/non-inverting inputs for Amplifier A and B; Pins 1 and 5 are their respective outputs; Pin 4 and 13 connect to V–; Pin 8 connects to V+; Pins 9, 11, and 12 are NC.
Can MAX436CPD operate from ±12V supplies?
Yes - MAX436CPD is fully specified for ±15V operation and functions reliably across ±5V to ±18V supply ranges. At ±12V, it maintains 12MHz GBW, 70V/µs slew rate, and ±13.5V input common-mode range, making it compatible with many mid-range industrial power architectures.
Does MAX436CPD have rail-to-rail input or output?
No - MAX436CPD does not feature rail-to-rail input or output. Its input common-mode range extends to ±13.5V with ±15V supplies, and output swing is typically ±12.5V under 2kΩ load. It is optimized for high-precision bipolar signal handling, not rail-sparing applications.
Where can I find the official MAX436CPD datasheet?
The official MAX436CPD datasheet is archived and accessible via Analog Devices' website under the legacy Maxim product documentation portal. Aetrix Electronics also provides a verified QuickView datasheet summary with key parameters, pinout diagram, and replacement guidance for MAX436CPD users.
