Product details
Overview
The MAX4022ESD+ from Maxim Integrated is a quad, high-speed, single-supply, closed-loop +2V/V buffer with rail-to-rail output swing, 200MHz -3dB bandwidth, 600V/µs slew rate, and ±120mA output drive capability. It operates from +3.15V to +11V (or ±1.575V to ±5.5V), features low differential gain/phase error (0.04%/0.02°), and is used in video line drivers, ADC interfaces, and CCD imaging systems.
For engineers reviewing the MAX4022ESD+ datasheet, MAX4022ESD+ pinout, MAX4022ESD+ application, or MAX4022ESD+ equivalent, key selection criteria include its quad-channel configuration, 14-pin SO package, rail-to-rail output swing under 150Ω load, 5.5mA quiescent current per amplifier, and verified performance in NTSC video signal conditioning with <0.04% differential gain error.
Technical Context
The MAX4022ESD+ implements voltage-feedback architecture enhanced with current-feedback techniques to achieve high slew rate and wide bandwidth while maintaining precision closed-loop gain of +2V/V (noninverting) or -1V/V (inverting) via internal 500Ω resistors. Its input stage extends 100mV beyond VEE, enabling ground-sensing operation in single-supply systems.
Local feedback around the output stage ensures low output impedance (<25mΩ DC) and demand-driven biasing for ±120mA drive into 20Ω loads, while total supply current remains ≤8.0mA per channel. It exhibits 10nV/√Hz input voltage noise and 1.3pA/√Hz input current noise, supporting high-fidelity analog signal paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad high-speed buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4019ESD+ | Includes enable (EN_) pin per channel; shutdown current = 400µA; same 14-pin SO package | Required for power-gated video subsystems needing dynamic channel disable | Select MAX4019ESD+ only if per-channel enable functionality is mandatory; MAX4022ESD+ offers lower cost and identical AC performance without enable logic |
| THS4032D | TI part: dual-channel, 260MHz BW, 350V/µs slew, no internal gain-setting resistors, requires external feedback network | Used where programmable gain or different closed-loop configurations (e.g., unity gain) are needed | Choose THS4032D when flexible gain configuration outweighs board space and component count advantages of MAX4022ESD+'s integrated +2V/V design |
Compared with MAX4019ESD+, the MAX4022ESD+ eliminates enable circuitry to reduce cost and complexity while retaining identical bandwidth, slew rate, and video fidelity - making it optimal for always-on video signal paths. Versus THS4032D, MAX4022ESD+ saves two external resistors per channel and guarantees gain accuracy without trimming.

FAQ
What is the maximum capacitive load the MAX4022ESD+ can drive without oscillation?
The MAX4022ESD+ is designed to drive up to 25pF of load capacitance without oscillation while maintaining stability. For larger capacitive loads (e.g., >25pF PCB traces or unterminated cables), an isolation resistor (e.g., 27Ω for 68pF) must be placed in series with the output, as documented in Figure 7 and Figure 9 of the MAX4022ESD+ datasheet. This prevents peaking and ensures phase margin remains sufficient for reliable operation.
Does the MAX4022ESD+ support dual-supply operation?
Yes, the MAX4022ESD+ supports dual-supply operation from ±1.575V to ±5.5V. In this configuration, VCC connects to the positive rail and VEE to the negative rail. The input voltage range extends 100mV beyond each rail, and outputs swing rail-to-rail - enabling symmetric signal handling in precision instrumentation and audio applications where bipolar supplies are required.
What is the typical differential gain and phase error of the MAX4022ESD+ in NTSC video applications?
The MAX4022ESD+ achieves a typical differential gain error of 0.04% and differential phase error of 0.02° under NTSC conditions (RL = 150Ω), as specified in the AC Electrical Characteristics table. These values are measured at f = 5MHz with 2Vp-p output and meet broadcast-grade video fidelity standards for professional routing, switching, and distribution equipment.
Can the MAX4022ESD+ be configured for inverting gain?
Yes, the MAX4022ESD+ supports inverting gain of −1V/V by using the inverting input (e.g., INA−) as the signal input and grounding the noninverting input (e.g., INA+). Internal 500Ω resistors set the gain precisely. For 50Ω systems, terminate the inverting input with a 56Ω resistor; for 75Ω systems, use 88Ω - ensuring proper impedance matching and minimizing reflections.
What is the quiescent supply current per amplifier in the MAX4022ESD+?
The MAX4022ESD+ draws 5.5mA of quiescent supply current per amplifier under typical operating conditions (VCC = +5V, VEE = 0V, TA = +25°C), with a maximum of 8.0mA across temperature. This enables low-power operation in battery-powered instruments and portable video equipment, with total quad-channel consumption remaining under 22mA at room temperature.
