Product details
Overview
MAX4022EEE+ 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 targets precision video line driving and ADC interface applications.
For engineers reviewing the MAX4022EEE+ datasheet, MAX4022EEE+ pinout, MAX4022EEE+ application, or MAX4022EEE+ equivalent, key selection criteria include guaranteed 200MHz small-signal bandwidth at 150Ω load, rail-to-rail output swing down to 60mV from rails, input voltage range extending 100mV beyond VEE, low 10nV/√Hz input voltage noise, and compatibility with 16-pin QSOP layout for multi-channel signal routing systems.
Technical Context
The MAX4022EEE+ implements a voltage-feedback architecture enhanced with current-feedback techniques to achieve high slew rate and wide bandwidth while maintaining closed-loop stability. Its internal 500Ω precision resistors fix 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, all while limiting quiescent current to 5.5mA per amplifier. Input common-mode range extends to VEE − 0.1V, supporting ground-sensing operation in single-supply video systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4032DR | Single-channel, 290MHz bandwidth, ±15V supply capable, no rail-to-rail output (clips ~2V from rails) | Requires external gain resistors; better suited for ±12V industrial instrumentation than single-supply video | Select when dual-supply operation and higher voltage headroom outweigh quad integration and rail-to-rail needs |
| LMH6723MA/NOPB | Triple-channel, 320MHz bandwidth, 1.1mA lower quiescent current, but 0.12%/0.15° differential gain/phase error | Higher distortion limits use in broadcast video; preferred for high-fidelity audio or RF IF stages | Choose for cost-sensitive, lower-distortion-tolerance applications where 3-channel count matches system topology |
Compared with THS4032DR and LMH6723MA/NOPB, MAX4022EEE+ uniquely combines quad-channel integration, true rail-to-rail output swing, and broadcast-grade video fidelity (0.04%/0.02°) in a single 16-pin QSOP-enabling compact, low-power, multi-channel video signal conditioning without external gain components or level-shifting circuitry.

FAQ
What is the operating supply voltage range for MAX4022EEE+?
MAX4022EEE+ operates from a single +3.15V to +11V supply or dual ±1.575V to ±5.5V supplies. At +5V single supply, it delivers full 200MHz bandwidth and rail-to-rail output swing. The device is characterized across −40°C to +85°C and requires 0.1µF bypass capacitors on VCC and VEE pins for stable operation.
Does MAX4022EEE+ support inverting gain configuration?
Yes, MAX4022EEE+ supports both +2V/V noninverting and −1V/V inverting configurations using its internal 500Ω precision resistors. For inverting mode, tie the noninverting input to ground and apply the signal to the inverting input. Input termination (e.g., 56Ω for 50Ω systems) is required to maintain impedance matching and minimize reflections.
What is the maximum capacitive load MAX4022EEE+ can drive stably?
MAX4022EEE+ remains stable driving up to 25pF of capacitive load without external compensation. For loads exceeding 25pF-such as unterminated PCB traces or unshielded cables-an isolation resistor (e.g., 27Ω for 120pF) between the output and load restores phase margin and suppresses peaking, as verified in Figure 9 of the datasheet.
How does MAX4022EEE+ achieve rail-to-rail output swing?
MAX4022EEE+ uses complementary bipolar output transistors biased via local feedback to enable output voltage swing within 60mV of VCC and VEE into 2kΩ loads. This architecture maintains linearity across the full supply range and eliminates dead zones near the rails-critical for preserving black/white levels in video signals.
Is MAX4022EEE+ pin-compatible with other devices in the MAX40xx family?
No, MAX4022EEE+ is not pin-compatible with MAX4014, MAX4017, or MAX4019 due to differing channel counts and pin assignments. MAX4022EEE+ is a quad amplifier in 16-pin QSOP; MAX4017 is dual in 8-pin SO/µMAX; MAX4019 is triple with enable in 14-pin SO/16-pin QSOP; and MAX4014 is single in 5-pin SOT23. Board redesign is required for substitution.
