Product details
Overview
MAX4436EUA+ from Maxim Integrated is a dual, unity-gain-stable, voltage-feedback operational amplifier optimized for high-speed 14- and 16-bit ADC driving applications. It delivers 150MHz small-signal -3dB bandwidth, 35ns 16-bit (0.0015%) settling time, 2.2nV/√Hz input voltage noise density, and ±65mA output drive capability in an 8-pin µMAX package.
For engineers reviewing the MAX4436EUA+ datasheet, MAX4436EUA+ pinout, MAX4436EUA+ application, or MAX4436EUA+ equivalent, key selection criteria include unity-gain stability, low-noise preamplification for precision converters, capacitive-load driving capability up to 30pF, and dual-channel integration for compact signal-chain designs.
Technical Context
The MAX4436EUA+ employs a voltage-feedback architecture with internal unity-gain compensation, enabling stable operation at AVCL = +1 without external compensation. Its 133V/µs slew rate and 28MHz large-signal -3dB bandwidth support fast transient response into 500Ω loads while maintaining 97dB SFDR at 1MHz with 4VP-P output.
Designed for single-supply operation from +4.5V to +5.5V, it features rail-to-rail output swing (within 200mV of VCC and 70mV of VEE), 115dB open-loop gain, and 100dB CMRR over 0–100kHz - critical for rejecting supply and common-mode noise in mixed-signal data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 150MHz at AVCL = +1 - enables accurate amplification of signals up to Nyquist frequency of 75Msps ADCs. |
| 16-Bit Settling Time | 35ns (0.0015% error) - ensures full resolution capture for 14-/16-bit ADCs sampling ≥28Msps. |
| Voltage Noise Density | 2.2nV/√Hz - preserves SNR in low-amplitude sensor and IF preamplifier stages. |
| Output Drive Current | ±65mA - drives 500Ω loads directly and sustains performance with 30pF capacitive loads. |
| Open-Loop Gain | 115dB typical - supports high-precision closed-loop gain accuracy and linearity. |
| Supply Voltage Range | +4.5V to +5.5V - compatible with standard 5V digital logic and LDO-regulated analog rails. |
| Input Offset Voltage | 1mV max - minimizes DC error in precision instrumentation and active filter topologies. |
Pinout & Package
MAX4436EUA+ is housed in an 8-pin µMAX® package (package code U8-1), measuring 3mm × 3mm × 0.8mm with exposed pad for thermal enhancement. The µMAX is a surface-mount, lead(Pb)-free/RoHS-compliant package with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - connects directly to ADC input or filter network; requires local 1nF bypass to ground. |
| 2 | INA− | Inverting input of Amplifier A - high-impedance node; must be shielded from noise and matched with INA+ trace length. |
| 3 | INA+ | Noninverting input of Amplifier A - reference point for differential input configuration; balanced layout critical. |
| 4 | VEE | Ground reference - connects to low-impedance ground plane; shared return path for both amplifiers. |
| 5 | INB+ | Noninverting input of Amplifier B - independent channel input; decoupled from Amplifier A's signal paths. |
| 6 | INB− | Inverting input of Amplifier B - maintains channel isolation; crosstalk ≤ −80dB at 1MHz confirmed. |
| 7 | OUTB | Amplifier B output - electrically isolated from OUTA; supports dual-channel simultaneous sampling. |
| 8 | VCC | Positive supply - requires dedicated 0.1μF ceramic + 10μF tantalum bypassing; routed separately from digital VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stability | Internally compensated for AVCL = +1 - eliminates need for external compensation components in buffer or gain-of-one configurations. |
| 16-bit settling in 35ns | Guaranteed 0.0015% error window - meets timing budget for 14-/16-bit SAR and pipeline ADCs operating ≥28Msps. |
| Low 2.2nV/√Hz noise | Preserves >97dB SFDR at 1MHz - essential for maintaining dynamic range in RF/IF receiver front-ends. |
| Dual-channel isolation | −80dB crosstalk at 1MHz - enables independent signal conditioning for I/Q or multi-channel data acquisition without interference. |
| Capacitive load drive | Stable with up to 30pF load - accommodates ADC input capacitance and PCB trace capacitance without external isolation resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual, high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8000ARZ | Single-channel, 1.5GHz GBW, higher supply current (18mA), no unity-gain compensation - requires external compensation for AVCL = +1. | Best suited for high-gain (>+10) RF amplification; not drop-in for dual-channel ADC driver use. | Select when >1GHz bandwidth is required and dual-channel integration is unnecessary. |
| LMH6629MA/NOPB | Dual-channel, 720MHz GBW, 1.9nV/√Hz noise, but only specified for AVCL ≥ +5 - unstable at unity gain. | Requires minimum gain of +5; unsuitable for unity-gain buffer or gain-of-two configurations used in many ADC interfaces. | Choose for high-gain, low-noise IF amplification where gain ≥+5 is acceptable and layout allows compensation. |
Compared with AD8000ARZ and LMH6629MA/NOPB, the MAX4436EUA+ uniquely combines dual-channel integration, guaranteed unity-gain stability, and 35ns 16-bit settling - making it the only option among the three qualified for space-constrained, low-latency, single-supply ADC driver designs requiring no external compensation.

FAQ
What is the maximum capacitive load the MAX4436EUA+ can drive without oscillation?
The MAX4436EUA+ remains stable with up to 30pF capacitive load without external isolation resistors, as verified in the Typical Operating Characteristics section (Figure MAX4434-37 toc19). This specification covers combined PCB trace capacitance and ADC input capacitance, supporting direct connection to most 14-/16-bit converters without added components.
Does the MAX4436EUA+ support single-supply operation?
Yes, the MAX4436EUA+ is explicitly designed for single-supply operation from +4.5V to +5.5V, with input common-mode range extending from VEE to VCC − 1V and rail-to-rail output swing (within 200mV of VCC and 70mV of VEE). This enables direct interfacing with 5V logic and ADCs without level-shifting circuitry.
Is the MAX4436EUA+ pin-compatible with other devices in the MAX4434–MAX4437 family?
No - the MAX4436EUA+ uses an 8-pin µMAX package with dual-amplifier pinout (OUTA, INA−, INA+, VEE, INB+, INB−, OUTB, VCC), while the single-channel MAX4434/MAX4435 use 5-pin SOT23 or 8-pin SO packages with different pin assignments. Pin compatibility exists only within same-channel-count variants sharing the same package type.
What is the guaranteed 16-bit settling time for the MAX4436EUA+?
The MAX4436EUA+ guarantees 35ns settling time to 0.0015% (16-bit) accuracy for a 1.5V to 3.5V output step under standard conditions (VCC = +5V, RL = 500Ω, TA = +25°C), as specified in the AC Electrical Characteristics table. This value is production-tested and applies to both amplifier channels.
How does the MAX4436EUA+ achieve low distortion in ADC driver applications?
The MAX4436EUA+ achieves −97dB spurious-free dynamic range (SFDR) at 1MHz with 4VP-P output by combining ultra-low 2.2nV/√Hz input voltage noise, 133V/µs slew rate, and optimized voltage-feedback architecture. Its 115dB open-loop gain and 100dB CMRR suppress harmonic generation and common-mode interference critical for preserving ADC ENOB.
