Product details
Overview
The 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, and 2.2nV/√Hz input voltage noise density while operating on a single +5V supply with 15mA per amplifier quiescent current.
For engineers reviewing the MAX4436EUA datasheet, MAX4436EUA pinout, MAX4436EUA application, or MAX4436EUA equivalent, this page provides verified specifications, µMAX package layout guidance, ADC preamplifier design context, and validated alternative op amps for high-fidelity signal chain design.
Technical Context
The MAX4436EUA implements a voltage-feedback architecture with internal unity-gain compensation, enabling stable operation at closed-loop gains ≥ +1 V/V. Its 133V/µs slew rate and 28MHz large-signal -3dB bandwidth support fast transient response into capacitive ADC inputs.
It features matched dual amplifiers in an 8-pin µMAX package, with guaranteed input offset voltage matching of 0.25mV and crosstalk of -80dB at 1MHz - critical for differential or multi-channel precision acquisition systems requiring channel-to-channel consistency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 150MHz at AVCL = +1 - supports wideband signal conditioning up to Nyquist of >75MSPS ADCs. |
| 16-Bit Settling Time | 35ns (0.0015%) - ensures full accuracy before next ADC sample clock edge in high-speed data acquisition. |
| Input Voltage Noise | 2.2nV/√Hz - preserves SNR when driving 16-bit ADCs with ≥97dB SFDR at 1MHz. |
| Slew Rate | 133V/µs - enables clean 4VP-P output swing without distortion at high frequencies. |
| Output Drive | ±65mA - drives 500Ω loads directly and sustains performance with 30pF capacitive load. |
| Supply Current | 15mA per amplifier - balances speed and power efficiency for dual-channel portable or dense PCB designs. |
| Input Offset Matching | 0.25mV (max) between amplifiers - minimizes gain/phase mismatch in dual-path or instrumentation topologies. |
Pinout & Package
The MAX4436EUA is housed in an 8-pin µMAX® package (package code U8-1), measuring 3mm × 3mm × 0.8mm with exposed pad for thermal enhancement. This RoHS-compliant, lead(Pb)-free surface-mount package supports high-density layouts and efficient heat dissipation in compact signal-chain modules.
| 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 - used for feedback configuration; sensitive to stray capacitance; keep trace short and guarded. |
| 3 | INA+ | Noninverting input - reference point for single-ended or differential input; match DC impedance to INA−. |
| 4 | VEE | Ground reference - connect to low-impedance analog ground plane; tie exposed pad to same plane. |
| 5 | INB+ | Amplifier B noninverting input - independent channel input; avoid coupling paths to INA+ or OUTA. |
| 6 | INB− | Amplifier B inverting input - mirror of INA−; maintain symmetrical layout for matched performance. |
| 7 | OUTB | Amplifier B output - electrically isolated from OUTA; crosstalk ≤ −80dB at 1MHz enables dual-channel integrity. |
| 8 | VCC | +5V supply - bypass with 0.1µF ceramic + 10µF tantalum; place 0.1µF within 2mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stability | Internally compensated for AVCL ≥ +1 V/V - eliminates external compensation components in buffer/gain=1 configurations. |
| Dual-channel matching | 0.25mV max input offset voltage matching - reduces common-mode error in differential receiver or I/Q demodulator stages. |
| Capacitive load drive | Stable with up to 30pF load - accommodates ADC input capacitance and PCB trace capacitance without external isolation resistors. |
| High-output current | ±65mA sourcing/sinking - drives 500Ω loads directly and maintains linearity under heavy transient loading. |
| Low harmonic distortion | −97dBc SFDR at 1MHz, 4VP-P - preserves dynamic range for 16-bit conversion without post-processing correction. |
Applications
| High-Speed ADC Preamplifier | IF Amplifier |

| Low-Distortion Active Filter | Precision Instrumentation Front-End |
|
Use Scenario: Implementing 4th-order Butterworth or Chebyshev active filters in medical imaging or spectrum analyzers where THD must remain < −90dB. IC Role / Device Role / Timing Role: Dual-op-amp section for biquad topology - one amplifier as integrator, second as summer/inverter. Use Value: Achieves < −97dBc SFDR at 1MHz due to ultra-low 2.2nV/√Hz noise and 133V/µs slew rate, eliminating filter-induced distortion artifacts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-distortion op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8009ARZ | Single-channel, 1GHz GBW, 5,500V/µs slew rate, higher supply current (17mA), not unity-gain stable. | Better for >200MHz small-signal gain stages; unsuitable for unity-gain buffers without external compensation. | Select AD8009ARZ only when >500MHz bandwidth is required and closed-loop gain ≥ +5 can be maintained. |
| LMH6629MA/NOPB | Dual-channel, 720MHz GBW, 3,500V/µs slew rate, 2.9nV/√Hz noise, unity-gain stable, 18mA per amp. | Higher bandwidth and slew rate but 32% higher noise and power; less optimal for 16-bit ADC drive at 100MSPS. | Choose LMH6629MA/NOPB when >300MHz bandwidth is needed and SFDR > −95dBc at 1MHz is acceptable. |
Compared with AD8009ARZ and LMH6629MA/NOPB, the MAX4436EUA offers superior 16-bit settling (35ns), lower noise (2.2nV/√Hz), and tighter dual-channel matching - making it the preferred choice for space-constrained, dual-channel, high-resolution ADC interface designs operating at ≤100MSPS.

FAQ
What is the maximum capacitive load the MAX4436EUA can drive without instability?
The MAX4436EUA remains stable with up to 30pF capacitive load at the output, as confirmed in the Typical Operating Characteristics section of the datasheet. For loads exceeding 30pF, a series isolation resistor (e.g., 10–50Ω) is recommended to preserve phase margin. This capability allows direct connection to typical 14-/16-bit ADC input capacitances without external compensation networks.
Does the MAX4436EUA support single-supply operation, and what is its input voltage range?
Yes, the MAX4436EUA is specified for single-supply operation from +4.5V to +5.5V (VCC to GND). Its input common-mode voltage range extends from VEE (GND) to VCC − 1V, enabling rail-to-rail input operation near ground while maintaining CMRR > 75dB. This makes it ideal for interfacing with ground-referenced sensors or ADCs in +5V systems.
How does the MAX4436EUA's 16-bit settling time compare to similar dual op amps?
The MAX4436EUA achieves 35ns settling to 16-bit accuracy (0.0015%), which is 2.5× faster than standard high-speed dual op amps like the AD8610 (90ns) and matches the performance of premium-grade devices such as the THS4521 (36ns). This is enabled by its 133V/µs slew rate and optimized voltage-feedback architecture - critical for sampling rates above 20MSPS.
Is the MAX4436EUA pin-compatible with other devices in the MAX443x family?
The MAX4436EUA shares the same 8-pin µMAX pinout with the MAX4437EUA, differing only in internal compensation (unity-gain vs. gain ≥ +5). It is not pin-compatible with SO-package variants (e.g., MAX4436ESA) due to different pin assignments, nor with single-channel parts (MAX4434/MAX4435), which use 5-pin SOT23 or 8-pin SO footprints.
What is the thermal performance of the MAX4436EUA in the µMAX package?
In the 8-pin µMAX package, the MAX4436EUA has a thermal resistance θJA of 222°C/W (derating 4.5mW/°C above +70°C), with a maximum continuous power dissipation of 330mW at +70°C ambient. The exposed pad must be soldered to a solid copper ground plane to achieve optimal thermal performance and ensure junction temperature stays below +150°C under full load.
