Product details
Overview
MAX4014EUK from Maxim Integrated is a precision, single-channel, closed-loop +2V/V (or –1V/V) rail-to-rail output buffer IC optimized for video and high-speed analog signal routing. It delivers 200MHz –3dB bandwidth, 600V/µs slew rate, ±120mA output drive, and operates from +3.15V to +11V single supply. It is used in portable video line drivers and ADC interface circuits where low power, wide bandwidth, and rail-to-rail swing are critical.
For engineers reviewing the MAX4014EUK datasheet, MAX4014EUK pinout, MAX4014EUK application, or MAX4014EUK equivalent, this page provides verified technical context, real-world design meaning of key specs, validated SOT23-5 pin mapping, application-specific use-value analysis, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The MAX4014EUK employs voltage-feedback architecture enhanced with current-feedback techniques to achieve high-speed performance while maintaining precision DC characteristics. Its internal 500Ω precision resistors fix closed-loop gain at +2V/V (noninverting) or –1V/V (inverting), eliminating external resistor matching requirements and reducing layout sensitivity.
It features rail-to-rail output swing (within 60mV of rails into 2kΩ), input range extending 100mV beyond VEE, and low noise (10nV/√Hz, 1.3pA/√Hz). The device draws only 5.5mA quiescent current and achieves 0.04% differential gain / 0.02° differential phase error - critical for NTSC/PAL video fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 200MHz –3dB small-signal bandwidth enables full HD video signal amplification without attenuation. |
| Slew Rate | 600V/µs supports fast transient response for composite video sync pulses and digital waveform edges. |
| Output Drive | ±120mA output current drives 50Ω/75Ω coaxial cables directly without external buffers. |
| Supply Range | +3.15V to +11V single supply simplifies power design in battery-powered or mixed-voltage systems. |
| Differential Error | 0.04% gain / 0.02° phase error preserves color fidelity in broadcast-quality video line driving. |
| Input Noise | 10nV/√Hz voltage noise and 1.3pA/√Hz current noise minimize SNR degradation in sensitive analog front-ends. |
| Quiescent Current | 5.5mA per amplifier allows integration into space- and power-constrained portable instrumentation. |
Pinout & Package
The MAX4014EUK is housed in a 5-pin SOT23-5 package (JEDEC MO-178AA), with exposed pad not electrically connected. Pin 1 is marked by a dot or beveled edge; top-marking "ABZQ" confirms authenticity.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VEE) | Negative supply / ground reference | Reference node for single-supply operation; input range extends 100mV below this pin. |
| 2 (IN–) | Inverting input terminal | Used for –1V/V gain configuration; presents 500Ω impedance requiring proper termination in 50Ω/75Ω systems. |
| 3 (IN+) | Noninverting input terminal | Primary signal input for +2V/V configuration; high-impedance node (3MΩ) minimizes loading on source. |
| 4 (OUT) | Amplifier output | Rail-to-rail capable output; drives 50Ω loads to ≥1.6Vpp under +5V supply with <0.1dB flatness to 30MHz. |
| 5 (VCC) | Positive supply | Accepts +3.15V to +11V; requires local 0.1µF ceramic bypass capacitor for stability at high frequencies. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed +2/–1 closed-loop gain | Eliminates external resistor selection errors and board space; ensures consistent gain across temperature and unit variance. |
| Rail-to-rail output swing | Delivers full dynamic range into ADCs or downstream stages without level-shifting circuitry. |
| Low differential gain/phase error | Enables direct replacement of legacy video op-amps in NTSC/PAL systems without recalibration. |
| High output current drive | Drives 50Ω/75Ω transmission lines directly, removing need for discrete emitter-follower or transformer coupling. |
| Single-supply operation down to +3.15V | Supports Li-ion (3.3V) and dual-cell alkaline (3V) portable designs without charge-pump or LDO overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMH6702MF/NOPB | Wider supply range (±5V to ±6V), higher quiescent current (12.5mA), no internal gain-setting resistors. | Requires external feedback network; better suited for variable-gain or high-voltage (>11V) systems. | Select when adjustable gain or dual-supply operation above ±5.5V is required; not drop-in for fixed +2V/V SOT23 layouts. |
| ADA4817-1AKSZ-R7 | Lower input bias current (1pA vs. 5.4µA), higher GBW (1GHz), but narrower supply range (+3V to +10V) and no rail-to-rail output. | Superior for ultra-low-input-bias applications like photodiode transimpedance; unsuitable for rail-to-rail output swing needs. | Choose for precision sensor interfaces demanding femtoampere-level bias; avoid where output must swing within 60mV of rails. |
Compared with LMH6702MF/NOPB and ADA4817-1AKSZ-R7, the MAX4014EUK uniquely combines factory-trimmed +2V/V gain, rail-to-rail output, 5.5mA quiescent current, and SOT23-5 footprint - making it optimal for cost-sensitive, space-constrained video and instrumentation designs where gain accuracy and power efficiency are prioritized over programmability or ultra-low bias.

FAQ
What is the operating temperature range for the MAX4014EUK?
The MAX4014EUK is specified for operation from –40°C to +85°C. All electrical characteristics over this full range are guaranteed by design, and the device undergoes 100% production testing at +25°C per the manufacturer's datasheet Note 1. This makes the MAX4014EUK suitable for industrial and automotive cabin environments where thermal cycling is expected.
Does the MAX4014EUK have an enable/disable function?
No, the MAX4014EUK does not include an enable pin. Only the MAX4019 variant in the same family features an EN_ input that reduces supply current to 400µA in shutdown mode. The MAX4014EUK remains fully enabled whenever powered; its 5.5mA quiescent current is fixed and cannot be reduced via external control.
Can the MAX4014EUK drive a 50Ω load effectively?
Yes, the MAX4014EUK can drive a 50Ω load effectively: it delivers ±120mA output current and maintains rail-to-rail swing (e.g., ≥1.6Vpp into 50Ω with +5V supply). Its 25Ω typical output impedance and 200MHz bandwidth ensure minimal signal degradation in video and RF cable-driving applications when properly terminated.
What is the input voltage range of the MAX4014EUK?
The MAX4014EUK input voltage range is from (VEE – 0.1V) to (VCC – 2.25V). In single-supply operation with VEE = 0V and VCC = +5V, this translates to –0.1V to +2.75V. The input extends 100mV beyond the negative rail, enabling true ground-sensing capability - critical for DC-coupled video and sensor interfaces.
Is the MAX4014EUK pin-compatible with other devices in the MAX4014/MAX4017/MAX4019/MAX4022 family?
No, the MAX4014EUK is not pin-compatible with other members of the family. It uses a 5-pin SOT23-5 package (pins: VEE, IN–, IN+, OUT, VCC), whereas MAX4017 uses 8-pin SO/µMAX, MAX4019 uses 14-pin SO or 16-pin QSOP, and MAX4022 uses 14-pin SO or 16-pin QSOP. Each variant has distinct pin counts, functions, and layouts.
