Product details
Overview
MAX4214EUK-T from Maxim Integrated is a precision, single-channel, closed-loop +2V/V or −1V/V rail-to-rail output buffer IC optimized for high-speed video and instrumentation signal conditioning. It delivers 230MHz −3dB bandwidth, 600V/µs slew rate, ±120mA output drive, and operates from a single 3.15V–11V supply. Its 5-pin SOT23 package enables compact placement in battery-powered video line drivers and ADC interface circuits.
For engineers reviewing the MAX4214EUK-T datasheet, MAX4214EUK-T pinout, MAX4214EUK-T application, or MAX4214EUK-T equivalent, key selection criteria include guaranteed rail-to-rail output swing under 150Ω load, differential gain/phase error of 0.03%/0.04° (NTSC), low 10nV/√Hz input voltage noise, and absence of enable/disable functionality-distinguishing it from MAX4215/MAX4219 variants.
Technical Context
The MAX4214EUK-T employs voltage-feedback architecture with internal 500Ω precision resistors to fix closed-loop gain at +2V/V (noninverting) or −1V/V (inverting), eliminating external gain-setting components. Its input common-mode range extends 100mV beyond VEE, supporting ground-sensing operation in single-supply systems.
Local feedback around the output stage ensures low output impedance (<200mΩ at 10MHz) and demand-driven biasing for high-current drive while maintaining quiescent current at only 5.5mA. No enable pin is present-unlike MAX4215/MAX4219-making it a dedicated always-on buffer for timing-critical signal paths.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4215ESA | Includes EN pin for shutdown (400µA ISD); same SOT23-5 not offered-available only in 8-pin SO/µMAX | Required where power cycling or standby mode is needed; incompatible pinout and package | Select MAX4215ESA only if enable functionality and SO/µMAX layout compatibility are mandatory |
| THS3201DGN | Higher 1.8GHz bandwidth but no internal gain resistors; requires external feedback network; 12V max supply | Better for RF (>100MHz) or wideband IF applications; lacks video-optimized differential error specs | Choose THS3201DGN when bandwidth >1GHz is critical and board area allows external resistors |
Compared with MAX4214EUK-T, MAX4215ESA adds disable control at the cost of larger packaging and different pinout, while THS3201DGN trades integrated gain accuracy and video linearity for raw speed and flexibility-making MAX4214EUK-T optimal for space-constrained, video-grade, always-on buffer roles.

FAQ
What is the operating supply voltage range for the MAX4214EUK-T?
The MAX4214EUK-T operates from a single 3.15V to 11V supply or dual ±1.575V to ±5.5V supplies. In single-supply mode, VEE is typically connected to ground, and VCC accepts 3.3V or 5V rails. The device maintains full AC performance across this range, with quiescent current increasing only modestly-from ~5.3mA at 3.3V to ~5.7mA at 5V-as confirmed in the "Power-Supply Current vs. Power-Supply Voltage" plot (MAX4214 toc28). This makes MAX4214EUK-T suitable for both modern low-voltage and legacy higher-voltage systems.
Does the MAX4214EUK-T have an enable/disable pin?
No, the MAX4214EUK-T does not include an enable/disable pin. Unlike the MAX4215/MAX4219 variants, which feature an EN_ input that reduces supply current to 400µA in shutdown mode, the MAX4214EUK-T is a fixed-function, always-active buffer. Its pinout (SOT23-5) contains only VEE, IN−, IN+, VCC, and OUT-no dedicated control terminal. This simplifies layout and eliminates enable timing concerns, making MAX4214EUK-T ideal for applications requiring deterministic, uninterrupted signal path behavior.
What gain configurations does the MAX4214EUK-T support?
The MAX4214EUK-T supports two closed-loop gain configurations using its internal 500Ω precision resistors: +2V/V in noninverting mode (IN− grounded, signal applied to IN+) and −1V/V in inverting mode (IN+ grounded, signal applied to IN−). The datasheet confirms these gains are factory-trimmed and require no external components. For 50Ω or 75Ω video applications, proper termination-e.g., 56Ω for 50Ω systems-is required at the inverting input in −1V/V mode to maintain impedance matching and minimize reflections, ensuring MAX4214EUK-T delivers specified differential gain/phase performance.
Can the MAX4214EUK-T drive 75Ω video loads reliably?
Yes, the MAX4214EUK-T is explicitly characterized for 75Ω video loads: typical differential gain/phase error (0.03%/0.04°) is measured at NTSC with RL = 150Ω, and large-signal pulse response plots (MAX4214 toc20, toc23) confirm stable 2VP-P output into 100Ω. Its ±120mA output drive capability exceeds the 66.7mA peak required for 2VP-P into 75Ω, and output swing remains >3.6VP-P into 150Ω at 5V supply per Figure MAX4214 toc18. Thus, MAX4214EUK-T reliably drives 75Ω coaxial lines in video routing and switching systems without external gain stages.
What is the input voltage noise density of the MAX4214EUK-T?
The MAX4214EUK-T has an input voltage noise density of 10nV/√Hz (typical, f = 1kHz), as specified in the AC Electrical Characteristics table and verified in the "Voltage-Noise Density vs. Frequency" plot (MAX4214 toc10). This low noise-combined with 1.3pA/√Hz input current noise-makes MAX4214EUK-T especially suitable for high-gain, wideband front-ends such as CCD imaging preamplifiers and precision instrumentation amplifiers where signal integrity at µV levels is critical. Noise performance remains flat from 100Hz to 10MHz, supporting broadband applications without added filtering.
