Product details
Overview
The MAX4019EEE+ from Maxim Integrated is a precision, triple-channel, closed-loop +2V/V (or –1V/V) buffer IC with rail-to-rail output swing, 200MHz –3dB bandwidth, 600V/µs slew rate, and integrated enable control. It operates from single +3.15V to +11V or dual ±1.575V to ±5.5V supplies, delivers ±120mA output current, and achieves 0.04% differential gain / 0.02° differential phase error - making it suitable for high-fidelity video line driving, ADC interface buffering, and CCD imaging signal conditioning.
For engineers reviewing the MAX4019EEE+ datasheet, MAX4019EEE+ pinout, MAX4019EEE+ application, or MAX4019EEE+ equivalent, key selection considerations include its 3-channel architecture with individual enable inputs, QSOP-16 package footprint, shutdown current of 400µA per channel, low 10nV/√Hz input voltage noise, and verified performance in NTSC video systems with 150Ω load termination.
Technical Context
The MAX4019EEE+ implements voltage-feedback topology enhanced with current-feedback techniques to achieve wide bandwidth and fast transient response. Its internal 500Ω precision resistors fix closed-loop gains at +2V/V (noninverting) or –1V/V (inverting), eliminating external gain-setting components.
Each of its three independent amplifiers features rail-to-rail output swing, input voltage range extending 100mV beyond VEE, and dedicated EN_ pins enabling per-channel power gating. The device maintains <0.1dB gain flatness up to 30MHz and delivers –78dBc SFDR at 5MHz under 2Vp-p output conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed video buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4017ESA+ | Dual-channel, no enable pins; 8-pin SO package; identical AC specs but lacks per-channel shutdown | Not suitable for power-gated multi-path systems; requires external logic for channel disable | Select when only two channels are needed and system-level power control suffices |
| THS3201DGN | Single-channel, 1.8GHz bandwidth, higher 12mA supply current, no internal gain resistors, SO-8 package | Requires external feedback network; better for ultra-wideband RF, less optimized for video DC-coupled gain | Select when >500MHz bandwidth is mandatory and board space allows discrete gain setting |
Compared with MAX4017ESA+, the MAX4019EEE+ adds third channel and per-amplifier enable-critical for scalable video routing. Versus THS3201DGN, it trades raw bandwidth for integrated gain, lower power, and video-optimized distortion specs-making it more suitable for cost-sensitive, multi-channel video infrastructure.

FAQ
What is the operating supply voltage range for the MAX4019EEE+?
The MAX4019EEE+ operates from a single +3.15V to +11V supply or dual ±1.575V to ±5.5V supplies. Its input voltage range extends from (VEE – 100mV) to (VCC – 2.25V), and outputs swing rail-to-rail into ≥2kΩ loads. This flexibility allows direct integration into both battery-powered portable instruments and fixed-line video infrastructure using standard 3.3V, 5V, or ±5V rails.
How does the enable feature work on the MAX4019EEE+?
The MAX4019EEE+ has three independent enable inputs (ENA, ENB, ENC), one per amplifier. When an EN_ pin is pulled low (≤ VEE + 0.5V), the corresponding amplifier enters shutdown mode, reducing its quiescent supply current to ≤400µA. Logic-high thresholds are VCC – 1.5V (VIH) and VCC – 2.6V (VIL). This per-channel control enables dynamic power management in multi-path video routing systems without disrupting other active channels.
Can the MAX4019EEE+ drive 75Ω video cables directly?
Yes - the MAX4019EEE+ delivers ±120mA output current and is characterized for 75Ω loads in NTSC applications. With proper 75Ω back-termination, it achieves 0.04% differential gain and 0.02° differential phase error. For optimal performance, use a 88Ω series resistor at the input when configured for inverting gain, and match output termination to cable impedance. The device's 200MHz bandwidth and 600V/µs slew rate ensure minimal group delay and edge degradation.
What is the typical input noise performance of the MAX4019EEE+?
The MAX4019EEE+ exhibits 10nV/√Hz input voltage noise density and 1.3pA/√Hz input current noise density at 1kHz. These values remain stable across frequency and temperature, supporting high-resolution signal chains in CCD imaging and precision instrumentation. The low noise floor contributes directly to its –78dBc spurious-free dynamic range at 5MHz, making it suitable for applications where SNR preservation is critical.
Is the MAX4019EEE+ pin-compatible with other devices in the MAX4014/MAX4017/MAX4019/MAX4022 family?
No - the MAX4019EEE+ uses a 16-pin QSOP package with unique pinout optimized for three independent amplifiers plus three enable inputs. It is not pin-compatible with the 5-pin SOT23 MAX4014, 8-pin SO/µMAX MAX4017, or 14-pin SO MAX4022. While functional behavior (gain, bandwidth, noise) is closely aligned across the family, mechanical and electrical pin mapping differs significantly due to channel count and enable architecture differences.
