Product details
Overview
The MAX4019ESD+ from Maxim Integrated is a precision, triple-channel, rail-to-rail output voltage buffer with closed-loop gain of +2 (or -1), designed for high-fidelity video and RF signal routing. It operates from +3.15V to +11V single supply (or ±1.575V to ±5.5V dual), delivers 200MHz -3dB bandwidth, 600V/µs slew rate, and features an enable pin for power management. It is used in video line drivers and ADC interface circuits where low distortion and wide bandwidth are critical.
For engineers reviewing the MAX4019ESD+ datasheet, MAX4019ESD+ pinout, MAX4019ESD+ application, or MAX4019ESD+ equivalent, key selection criteria include its 3-channel configuration, EN_ control logic, 14-pin SO package, rail-to-rail output swing (±120mA drive), and verified differential gain/phase error of 0.04%/0.02° in NTSC systems.
Technical Context
The MAX4019ESD+ implements voltage-feedback architecture enhanced with current-feedback techniques to achieve high slew rate and bandwidth while maintaining precision DC performance. Its internal 500Ω resistors fix closed-loop gain at +2V/V (noninverting) or -1V/V (inverting), eliminating external gain-setting components.
Each of its three independent amplifiers includes dedicated enable inputs (ENA, ENB, ENC), supports input voltage range extending 100mV beyond VEE, and delivers rail-to-rail output swing into 150Ω loads. The device uses local feedback around the output stage to maintain low output impedance (<25mΩ) and enable ±120mA drive capability without exceeding 5.5mA per amplifier quiescent current.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, precision buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4019EEE+ | Same electrical specs but in 16-pin QSOP package - larger footprint, higher parasitic capacitance, different pinout layout. | Preferred for space-constrained PCBs where SO lead pitch causes solder bridging; less suitable for automated optical inspection due to gull-wing leads. | Select MAX4019EEE+ only if board layout requires QSOP mechanical compatibility or existing QSOP footprint reuse. |
| THS3201D | Single-channel, 1.8GHz bandwidth, 4300V/µs slew rate, no enable pin, higher supply current (12.5mA), no internal gain resistors. | Better for ultra-wideband RF applications requiring >500MHz bandwidth; unsuitable for multi-channel video routing due to single-channel count and lack of EN_ control. | Choose THS3201D only when bandwidth >1GHz is mandatory and per-channel power gating is unnecessary. |
Compared with MAX4019ESD+, MAX4019EEE+ offers identical performance in a different package but requires PCB redesign, while THS3201D trades channel count and power control for raw speed - making MAX4019ESD+ optimal for cost-sensitive, multi-channel, power-aware video signal conditioning.

FAQ
What is the operating temperature range for the MAX4019ESD+?
The MAX4019ESD+ is specified for operation from -40°C to +85°C ambient temperature. This industrial temperature grade ensures reliable performance in portable instruments, video surveillance enclosures, and factory-floor embedded systems where thermal cycling occurs. All DC and AC specifications - including gain accuracy, bandwidth, and distortion - are guaranteed across this full range.
Does the MAX4019ESD+ require external resistors to set gain?
No, the MAX4019ESD+ does not require external resistors to set gain. It integrates precision 500Ω internal resistors per channel to deliver fixed closed-loop gains of +2V/V (noninverting) or -1V/V (inverting). This eliminates gain-setting component variation, board space, and calibration steps - a key advantage over general-purpose op-amps when implementing video line drivers or ADC buffers.
How does the enable function work on the MAX4019ESD+?
The MAX4019ESD+ has three independent enable inputs (ENA, ENB, ENC), one per amplifier. Driving any EN_x pin below VCC − 2.6V disables that channel, reducing its quiescent supply current to 400µA. The output enters high-impedance state with 1kΩ disabled output resistance. This allows selective power-down of unused channels in multi-buffer systems without affecting others - a feature absent in MAX4014/MAX4017 variants.
Can the MAX4019ESD+ drive 75Ω coaxial cable directly?
Yes, the MAX4019ESD+ can drive 75Ω coaxial cable directly when configured in noninverting gain-of-2 mode with proper termination. Its ±120mA output drive and rail-to-rail swing support 2Vp-p into 75Ω, and its 0.04%/0.02° differential gain/phase error meets NTSC broadcast requirements. For best results, terminate the far end of the cable and use a 49.9Ω series resistor at the output to match characteristic impedance and suppress reflections.
What is the maximum capacitive load the MAX4019ESD+ can drive stably?
The MAX4019ESD+ remains stable driving up to 25pF of capacitive load without external compensation. Beyond that, oscillation risk increases due to phase margin degradation. To drive larger loads (e.g., 68pF), a series isolation resistor (e.g., 27Ω) between the output and load restores stability - as validated in Maxim's Figure 9. This technique preserves bandwidth while preventing peaking and ringing in video signal paths.
