Product details
Overview
MAX4022ESD from Maxim Integrated is a quad-channel, precision, closed-loop +2-gain buffer with rail-to-rail output swing, 200MHz -3dB bandwidth, 600V/µs slew rate, and ±120mA output drive capability. It operates from single +3.15V to +11V or dual ±1.575V to ±5.5V supplies, features low differential gain/phase error (0.04%/0.02°), and targets high-fidelity video line driving and ADC interface applications.
For engineers reviewing the MAX4022ESD datasheet, MAX4022ESD pinout, MAX4022ESD application, or MAX4022ESD equivalent, this page delivers verified technical context, real-world design meaning for key specs, validated SO-14 pin mapping, application-specific implementation insights, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The MAX4022ESD implements voltage-feedback architecture enhanced with current-feedback techniques to achieve its 600V/µs slew rate and 200MHz small-signal bandwidth. Its internal 500Ω precision resistors fix closed-loop gain at +2V/V (noninverting) or -1V/V (inverting), eliminating external gain-setting components.
Local feedback around the output stage ensures low output impedance (<25mΩ DC) and demand-driven biasing for ±120mA drive into 20Ω loads while maintaining quiescent supply current at 5.5mA per amplifier. Input voltage range extends 100mV beyond VEE, supporting ground-sensing operation in single-supply systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 200MHz -3dB - supports full HD video signal integrity up to 1080p60 without attenuation. |
| Slew Rate | 600V/µs - enables clean 5MHz sine-wave reproduction with <0.04% differential gain error. |
| Output Drive | ±120mA - drives 50Ω coaxial cables directly or sustains 1.6Vpp swing into 50Ω at +5V supply. |
| Supply Current | 5.5mA per amplifier - enables four-channel buffering in portable instruments with <22mA total ICC. |
| Differential Error | 0.04% DG / 0.02° DP - meets NTSC/PAL broadcast-grade video fidelity requirements. |
| Noise Density | 10nV/√Hz voltage noise - preserves SNR in analog front-end signal chains before ADC sampling. |
| Input Range | VEE − 0.1V to VCC − 2.25V - allows input signals down to ground in single-supply +5V systems. |
Pinout & Package
MAX4022ESD is packaged in a 14-pin SO (Small Outline) surface-mount package with standard JEDEC MO-153 footprint and 1.27mm pitch. Pin 1 is marked by a beveled corner or dot; device orientation follows standard SO top-view convention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4019ESD | Quad-channel like MAX4022ESD but includes enable (EN_) pins per amplifier; shutdown current = 400µA per channel. | Required where dynamic power gating is needed (e.g., battery-powered portable scopes); MAX4022ESD has no enable function. | Select MAX4019ESD only if per-channel disable capability is mandatory; otherwise MAX4022ESD offers simpler control. |
| THS4631D | Single-channel, JFET-input op amp; 300MHz GBW, 400V/µs slew rate; no internal gain-setting resistors; requires external feedback network. | Used when variable gain or unity-gain stability is required; not drop-in compatible due to different topology and pinout. | Choose THS4631D for design flexibility in non-standard gain configurations; MAX4022ESD is optimized for fixed +2/−1 with minimal BOM. |
Compared with MAX4019ESD, MAX4022ESD trades enable functionality for lower system complexity and identical AC performance; versus THS4631D, it sacrifices gain programmability for guaranteed +2/−1 accuracy, reduced layout sensitivity, and true quad integration in one SO-14 package.

FAQ
What is the operating supply voltage range for MAX4022ESD?
The MAX4022ESD operates from a single supply of +3.15V to +11V or dual supplies of ±1.575V to ±5.5V. At +5V single supply, it delivers full rail-to-rail output swing into 150Ω loads and maintains 200MHz bandwidth. The input common-mode range extends 100mV below VEE, enabling ground-referenced inputs in portable instrumentation using MAX4022ESD.
Does MAX4022ESD have an enable/disable function like MAX4019?
No, MAX4022ESD does not include an enable pin. Unlike the MAX4019ESD-which provides per-amplifier EN_ inputs reducing supply current to 400µA in shutdown-the MAX4022ESD lacks enable logic entirely. Its quiescent current remains fixed at 5.5mA per amplifier under all operating conditions, making MAX4022ESD suitable for always-on video routing or continuous-sampling systems where power gating is unnecessary.
What is the maximum capacitive load MAX4022ESD can drive without instability?
The MAX4022ESD is stable driving up to 25pF of capacitive load with no external compensation. Beyond that, peaking and potential oscillation occur due to added phase lag. For loads >25pF (e.g., long PCB traces or unterminated cables), an isolation resistor (e.g., 27Ω for 68pF) must be placed in series with the output, as validated in Figure 9 of the MAX4022ESD datasheet. This preserves stability while maintaining usable bandwidth.
How does MAX4022ESD achieve 0.04% differential gain error?
MAX4022ESD achieves 0.04% differential gain error through precision-matched internal 500Ω feedback resistors, low-distortion output stage design, and optimized voltage-feedback architecture with current-feedback enhancements. This performance is measured under NTSC conditions (RL = 150Ω) and is guaranteed over −40°C to +85°C, making MAX4022ESD suitable for broadcast-quality video line drivers where color fidelity is critical.
Can MAX4022ESD be used in inverting configuration, and what input termination is required?
Yes, MAX4022ESD supports inverting configuration (gain = −1V/V) by using the inverting input as the signal path and grounding the noninverting input. Due to its 500Ω inverting input impedance, a 56Ω series terminator is required for 50Ω systems, and an 88Ω terminator for 75Ω video applications. This ensures proper impedance matching and minimizes reflections-critical for maintaining MAX4022ESD's specified differential phase accuracy.
