Product details
Overview
The MAX4014EUK-T from Maxim Integrated is a precision, single-channel, closed-loop +2V/V (or −1V/V) voltage buffer IC optimized for high-speed video and RF signal routing. It delivers 200MHz −3dB bandwidth, 600V/µs slew rate, rail-to-rail output swing, and ultra-low differential gain/phase error (0.04%/0.02°), operating from a single +3.15V to +11V supply. It is widely deployed as a 75Ω video line driver in portable instrumentation and ADC interface circuits.
For engineers reviewing the MAX4014EUK-T datasheet, MAX4014EUK-T pinout, MAX4014EUK-T application, or MAX4014EUK-T equivalent, key selection criteria include its SOT23-5 package footprint, guaranteed −40°C to +85°C operation, 5.5mA quiescent current, ±120mA output drive, and precise internal 500Ω feedback resistors enabling fixed-gain configurations without external components.
Technical Context
This device uses voltage-feedback architecture enhanced with current-feedback techniques to achieve both wide bandwidth and high slew rate. Its internal 500Ω precision resistors set closed-loop gain to exactly +2V/V (noninverting) or −1V/V (inverting), eliminating gain-setting resistor tolerance errors.
The input stage extends 100mV beyond the negative rail (VEE), supporting ground-sensing in single-supply systems, while the rail-to-rail output drives loads down to 20Ω with <60mV headroom to rails. Local output-stage feedback ensures low impedance (<25mΩ DC) and demand-driven biasing for robust ±120mA sourcing/sinking capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (−3dB) | 200MHz - supports full NTSC/PAL video baseband and 5MHz–10MHz instrumentation signals without attenuation. |
| Slew Rate | 600V/µs - enables clean 2Vpp step response with <1ns rise/fall time into 100Ω, critical for fast pulse integrity. |
| Output Drive | ±120mA - drives 50Ω/75Ω coaxial cables directly or heavy capacitive loads when combined with isolation resistors. |
| Differential Gain/Phase | 0.04%/0.02° - meets broadcast-grade video fidelity requirements; eliminates visible color distortion in analog video paths. |
| Supply Current | 5.5mA (typ.) - enables battery-powered portable instruments with multi-hour runtime on coin-cell or Li-ion sources. |
| Input Voltage Noise | 10nV/√Hz - preserves SNR in low-level signal conditioning stages preceding ADCs or CCD readout circuits. |
| Operating Supply Range | +3.15V to +11V single supply - compatible with 3.3V and 5V logic domains without level-shifting circuitry. |
Pinout & Package
MAX4014EUK-T is housed in a 5-pin SOT23-5 package (JEDEC MO-178AA), with exposed pad not electrically connected. The package measures 2.9mm × 1.6mm × 1.1mm and is RoHS-compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VEE) | Negative power supply / ground reference | Return path for bias and signal; input range extends 100mV below this pin, enabling true ground-referenced inputs in single-supply mode. |
| 2 (IN−) | Inverting input terminal | 500Ω input impedance; used with IN+ to configure −1V/V gain; requires 56Ω/88Ω termination in 50Ω/75Ω systems. |
| 3 (IN+) | Noninverting input terminal | 3MΩ input resistance; primary signal entry for +2V/V configuration; grounded for inverting mode. |
| 4 (VCC) | Positive power supply | Accepts +3.15V to +11V; must be bypassed with 0.1µF ceramic capacitor placed adjacent to pin for high-frequency stability. |
| 5 (OUT) | Amplifier output | Rail-to-rail capable; drives 2kΩ load within 60mV of rails; output impedance <25mΩ at DC, rising with frequency per closed-loop design. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed +2V/V or −1V/V gain | Internal 500Ω matched resistors eliminate external gain-setting components and associated tolerance drift. |
| Rail-to-rail output swing | Delivers full dynamic range into 2kΩ loads (e.g., ADC input buffers), maximizing signal utilization in low-voltage systems. |
| Low distortion at 5MHz | −78dBc SFDR and −75dB THD enable high-fidelity signal reproduction in CCD imaging and video digitization paths. |
| Ultra-low noise performance | 10nV/√Hz voltage noise and 1.3pA/√Hz current noise preserve resolution in precision analog front-ends. |
| High-speed video optimization | 0.04%/0.02° differential gain/phase error meets SMPTE/ITU-R BT.601 broadcast standards for composite video. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3201DBVR | Higher 1.8GHz bandwidth but 12mA ICC; no internal gain-setting resistors; requires external feedback network. | Better suited for RF IF amplification >100MHz; less optimal for video due to higher power and layout sensitivity. | Choose THS3201DBVR only when >500MHz small-signal bandwidth is required and board space allows for precision external resistors. |
| LMH6702MF/NOPB | 2.1GHz bandwidth, 3.2mA ICC, but 0.15%/0.1° DG/DP; no rail-to-rail output; SO-8 package. | Acceptable for non-broadcast video or general-purpose high-speed buffering where differential gain/phase is not critical. | Select LMH6702MF/NOPB when cost and bandwidth outweigh video fidelity requirements; avoid in broadcast or medical imaging systems. |
Compared with THS3201DBVR and LMH6702MF/NOPB, the MAX4014EUK-T offers superior video-grade linearity (0.04%/0.02°), lower power (5.5mA vs. ≥3.2mA), integrated gain resistors, and SOT23-5 footprint-making it the optimal choice for space-constrained, low-power, broadcast-compliant video and instrumentation designs.

FAQ
What is the maximum capacitive load the MAX4014EUK-T can drive without oscillation?
The MAX4014EUK-T is stable driving up to 25pF of capacitive load with no external compensation. For larger loads (e.g., >47pF), an isolation resistor (e.g., 27Ω for 120pF) must be placed in series with the output to maintain phase margin and prevent peaking or oscillation, as verified in Figure 9 of the datasheet. This is essential when driving long PCB traces or unterminated cables.
Does the MAX4014EUK-T support dual-supply operation?
Yes, the MAX4014EUK-T operates from dual supplies ranging from ±1.575V to ±5.5V. In dual-supply mode, VEE connects to the negative rail (e.g., −5V) and VCC to the positive rail (e.g., +5V). Input common-mode range extends 100mV beyond each rail, and outputs swing rail-to-rail-enabling symmetric signal handling in bipolar signal chains such as audio or instrumentation amplifiers.
How is gain configured on the MAX4014EUK-T?
The MAX4014EUK-T achieves fixed +2V/V gain by grounding the IN− pin and applying the signal to IN+. For −1V/V inverting gain, ground IN+ and apply the signal to IN−. Internal 500Ω resistors set the gain ratio precisely-no external resistors are needed. Termination resistors (e.g., 49.9Ω for noninverting, 56Ω for inverting in 50Ω systems) are recommended at the input to match source impedance and minimize reflections.
What is the input voltage range specification for the MAX4014EUK-T?
The MAX4014EUK-T features an extended input voltage range from (VEE − 0.1V) to (VCC − 2.25V). When operated from a +5V single supply (VEE = 0V), this translates to −0.1V to +2.75V. With ground-sensing capability, the effective usable range in noninverting +2V/V mode becomes approximately 20mV to 1.7V-ensuring linear operation for low-level video and sensor signals near ground potential.
Is the MAX4014EUK-T pin-compatible with other devices in the MAX4014/MAX4017/MAX4019/MAX4022 family?
No-the MAX4014EUK-T (SOT23-5, single channel) is not pin-compatible with MAX4017 (dual, SO/µMAX), MAX4019 (quad with enable, SO/QSOP), or MAX4022 (quad, SO/QSOP). Each variant has distinct pin counts, functions, and layouts. Only the MAX4014EUK-T and MAX4014EUK+ share identical pinout and functionality; substitution requires verifying package, channel count, and enable functionality against the target application.
