Product details
Overview
MAX4436ESA 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 MAX4436ESA datasheet, MAX4436ESA pinout, MAX4436ESA application, or MAX4436ESA equivalent, this device is selected for precision high-frequency signal conditioning where low distortion, fast settling, and rail-to-rail output swing are critical - especially in data acquisition front-ends requiring >97dB SFDR at 1MHz.
Technical Context
The MAX4436ESA integrates two independent amplifiers in an 8-pin SO package, each internally compensated for unity-gain stability. Its voltage-feedback architecture enables predictable frequency response and phase margin control, supporting stable operation into capacitive loads up to 30pF when used with series isolation resistors.
It operates from a single +4.5V to +5.5V supply, features rail-swinging outputs (within 200mV of VCC and 70mV of VEE), and maintains ≥100dB open-loop gain across temperature. Input common-mode range extends from VEE to VCC − 1V, enabling direct interfacing with modern SAR and pipeline ADC reference voltages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal -3dB Bandwidth | 150MHz - supports full-power analog bandwidth for 100+ MSPS ADC sampling without gain roll-off. |
| 16-Bit Settling Time | 35ns (0.0015%) - ensures accurate sampling of fast transient signals before ADC aperture time closes. |
| Input Voltage Noise Density | 2.2nV/√Hz - preserves SNR in low-amplitude, wideband sensor or IF signal chains. |
| Spurious-Free Dynamic Range | −97dBc at 1MHz, 4VP-P - meets dynamic range requirements of 16-bit ADCs without harmonic contamination. |
| Output Drive Current | ±65mA - drives 500Ω loads directly and sustains fast slewing into typical ADC input capacitance. |
| Supply Current per Amplifier | 15–18mA - balances high-speed performance with power efficiency in dual-channel systems. |
| Open-Loop Gain | 100–115dB - provides sufficient loop gain for precise closed-loop gain accuracy and linearity. |
Pinout & Package
MAX4436ESA is housed in an 8-pin SO (Small Outline) package, RoHS-compliant, with standard JEDEC MS-012AC footprint. Pin 1 is marked by a beveled corner or dot; the package supports surface-mount reflow assembly and thermal dissipation up to 471mW at +70°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives external load or ADC input; capable of ±65mA sourcing/sinking. |
| 2 | INA− | Inverting input - forms feedback node in inverting configurations; matched to INA+ for CMRR optimization. |
| 3 | INA+ | Noninverting input - accepts differential or single-ended signal source; input bias current ≤22µA. |
| 4 | VEE | Ground reference - must connect to low-impedance system ground plane to maintain AC performance. |
| 5 | INB+ | Amplifier B noninverting input - electrically isolated from Amplifier A; supports dual-channel independent signal paths. |
| 6 | INB− | Amplifier B inverting input - shares same electrical characteristics as INA−; crosstalk ≤−80dB at 1MHz. |
| 7 | OUTB | Amplifier B output - identical drive capability and settling behavior as OUTA. |
| 8 | VCC | Positive supply - requires local 0.1µF ceramic + 10µF tantalum bypassing to suppress high-frequency supply noise. |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stability | Internally compensated for AVCL = +1V/V - eliminates need for external compensation in buffer or gain-of-one configurations. |
| 16-bit accurate settling | 35ns to 0.0015% error - enables use with 16-bit ADCs sampling at ≥20MSPS without post-processing correction. |
| Rail-swinging output | VOL ≤ 70mV above VEE, VOH ≥ VCC − 200mV - maximizes dynamic range when driving single-supply ADCs. |
| Low distortion at high frequency | −97dBc SFDR at 1MHz - preserves signal integrity in IF/RF receiver chains and precision instrumentation. |
| Dual independent amplifiers | No internal coupling - allows simultaneous processing of two channels with <−80dB crosstalk at 1MHz. |
Applications
| High-Speed ADC Preamplifier | IF/RF Signal Conditioning |

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 | Higher slew rate (4100V/µs) but lower open-loop gain (95dB), wider supply range (±5V to ±6V), no unity-gain compensation - requires external compensation for G=1. | Better suited for high-voltage, high-slew applications like pulse amplification; less optimal for precision ADC driving due to lower DC gain and higher distortion at 1MHz. | Select AD8000ARZ only when >1000V/µs slew is required and unity-gain stability is not mandatory. |
| LMH6629MA/NOPB | Lower noise (1.9nV/√Hz), higher bandwidth (1.5GHz), but higher quiescent current (22mA per amp), not unity-gain stable - requires minimum G=5. | Ideal for ultra-low-noise IF amplification above 100MHz; unsuitable for unity-gain ADC buffer roles without redesigning feedback network. | Choose LMH6629MA/NOPB for RF/IF stages demanding lowest noise floor above 50MHz, not for general-purpose ADC driver replacement. |
Compared with AD8000ARZ and LMH6629MA/NOPB, MAX4436ESA offers guaranteed unity-gain stability, lower power per channel (15mA), and tighter DC specifications (100dB min open-loop gain, 1mV max VOS), making it uniquely suitable for precision, single-supply, dual-channel ADC interface designs without layout or compensation changes.

FAQ
What is the maximum capacitive load the MAX4436ESA can drive without oscillation?
The MAX4436ESA can drive up to 30pF without sustained oscillations, as specified in the Absolute Maximum Ratings table. For loads exceeding 15pF, a series isolation resistor (RISO) of 5Ω–50Ω is recommended between the output and capacitive load to restore phase margin and suppress ringing - verified in Typical Operating Characteristics Figure 3 and toc19.
Does the MAX4436ESA support single-supply operation?
Yes, the MAX4436ESA is explicitly designed for single-supply operation from +4.5V to +5.5V (VEE = 0V). Its input common-mode range extends from VEE to VCC − 1V, and its output swings within 70mV of VEE and 200mV of VCC, enabling direct interfacing with single-supply ADCs and sensors without level-shifting circuitry.
What is the guaranteed 16-bit settling time for the MAX4436ESA?
The MAX4436ESA guarantees 35ns settling time to 0.0015% (16-bit accuracy) for a 1.5V to 3.5V step under standard conditions (VCC = +5V, RL = 500Ω, TA = +25°C), as documented in the AC Electrical Characteristics table. This value is production-tested and holds across the full −40°C to +85°C operating temperature range per design guarantee.
Is the MAX4436ESA pin-compatible with other devices in the MAX443x family?
No - the MAX4436ESA (dual, 8-pin SO) is not pin-compatible with the single-amplifier MAX4434ESA (also 8-pin SO), because pin functions differ: MAX4434ESA uses pins 1–5 identically to SOT23 mapping (OUT, VEE, IN+, IN−, VCC), while MAX4436ESA assigns pins 1/7 to OUTA/OUTB and pins 2/3/5/6 to dedicated inverting/noninverting inputs for each amplifier. Always verify pin configuration against the SO package diagram on page 10.
What is the input voltage noise density of the MAX4436ESA, and at what frequency is it measured?
The MAX4436ESA has a typical input voltage noise density of 2.2nV/√Hz, measured at 100kHz (per AC Electrical Characteristics table). This value remains stable from 1kHz to 10MHz, as confirmed in Figure toc25, making it suitable for wideband applications where integrated noise over 100kHz–10MHz dominates total noise contribution.
