Product details
Overview
MAX4222EEE from Maxim Integrated is a quad-channel, precision, closed-loop, gain-of-+2 (or -1) rail-to-rail output buffer IC optimized for high-speed video and RF signal routing. It delivers 230MHz -3dB bandwidth, 600V/µs slew rate, ±120mA output drive, and 0.03%/0.04° differential gain/phase error across all four channels. It operates from a single 3.15V to 11V supply and targets video multiplexing, CCD imaging, and ADC interface applications.
For engineers reviewing the MAX4222EEE datasheet, MAX4222EEE pinout, MAX4222EEE application, or MAX4222EEE equivalent, key selection criteria include guaranteed quad-channel matching, QSOP-16 package compatibility, rail-to-rail output swing under 150Ω load, low 5.5mA per-channel quiescent current, and absence of enable/disable functionality (unlike MAX4215/MAX4219).
Technical Context
The MAX4222EEE employs voltage-feedback architecture with internal 500Ω precision resistors to fix closed-loop gain at +2V/V (noninverting) or -1V/V (inverting), eliminating external gain-setting components. Its local feedback loop ensures low output impedance and demand-driven biasing for high-current drive without sacrificing power efficiency.
It features input common-mode range extending 100mV beyond VEE, rail-to-rail output swing into 2kΩ, and maintains 90MHz 0.1dB gain flatness - critical for NTSC/PAL video fidelity. Unlike MAX4215/MAX4219, it has no enable pin and is not shutdown-capable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 4 independent buffers - enables compact multi-channel video routing without inter-channel crosstalk degradation (typical -95dB at 10MHz) |
| -3dB Bandwidth | 230MHz - supports full HD baseband video and wideband RF signal conditioning up to ~115MHz fundamental |
| Slew Rate | 600V/µs - ensures faithful reproduction of fast video edges and transient-rich waveforms without distortion |
| Output Drive | ±120mA - drives 50Ω/75Ω coaxial lines directly or sustains 150Ω loads with >3.5Vp-p swing at 5V supply |
| Differential Error | 0.03% DG / 0.04° DP - meets broadcast-grade video spec (SMPTE RP-168) for minimal color fidelity loss |
| Supply Current | 5.5mA per channel - total 22mA quiescent draw enables low-power multi-buffer designs in portable instrumentation |
| Input Noise | 10nV/√Hz voltage noise - preserves SNR in high-gain analog front-ends such as CCD sensor interfaces |
Pinout & Package
MAX4222EEE is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.635mm pitch), optimized for high-density PCB layouts while maintaining thermal performance up to +85°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | OUTA / OUTD | Amplifier A/D outputs - rail-to-rail capable, each drives ±120mA into 50Ω/75Ω loads |
| 2, 15 | INC− / IND− | Inverting inputs for channels C/D - 500Ω internal termination sets fixed -1V/V gain when used |
| 3, 14 | INC+ / IND+ | Noninverting inputs for channels C/D - 500Ω internal termination sets +2V/V gain when IN− grounded |
| 4, 13 | VEE | Negative supply or ground reference - input common-mode extends 100mV below VEE for single-supply operation |
| 5, 12 | VCC | Positive supply - accepts 3.15V–11V single supply or ±1.575V–±5.5V dual supplies |
| 6, 11 | ENB / ENC | No connection - MAX4222 has no enable function; pins are NC and must be left floating or tied to VEE |
| 7, 10 | INA− / INB− | Inverting inputs for channels A/B - identical 500Ω internal resistor network as channels C/D |
| 8, 9 | INA+ / INB+ | Noninverting inputs for channels A/B - fully matched to other channels for gain consistency and crosstalk control |
Key Features
| Feature | Design Value |
|---|---|
| Fixed closed-loop gain | Internal 500Ω resistors set precise +2V/V (noninverting) or -1V/V (inverting) - eliminates gain drift and external component count |
| Rail-to-rail output | Swings within 60mV of VEE/VCC into 2kΩ - maximizes dynamic range in 3.3V/5V systems without level-shifting circuitry |
| Low distortion at 5MHz | -72dBc SFDR and -71dB THD - preserves signal integrity in high-fidelity video digitization and RF sampling paths |
| High channel matching | 0.1dB gain matching between channels - essential for synchronized multi-path video switching and beamforming |
| Robust input protection | Back-to-back Schottky diodes between IN+ and IN− - withstand ±5V differential overvoltage without latch-up |
Applications
| Video Multiplexing Applications | CCD Imaging 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 |
|---|---|---|---|
| MAX4219EEE | Triple-channel, includes EN pin for shutdown (400µA disabled current); same 230MHz BW and 0.03%/0.04° DG/DP | Requires enable logic and board space for three channels only; unsuitable where quad-channel density is mandatory | Select MAX4219EEE only if system requires selective channel shutdown and channel count can be reduced from four to three |
| MAX4217ESA | Dual-channel, SO-8 package; no enable; identical core specs but half the channel count and different footprint | Needs two ICs to match MAX4222EEE's quad functionality - increases BOM count, layout area, and inter-channel skew risk | Choose MAX4217ESA only for cost-sensitive dual-channel designs where QSOP-16 footprint is unavailable or undesirable |
Compared with MAX4219EEE and MAX4217ESA, MAX4222EEE uniquely delivers four matched, enable-free buffers in a single QSOP-16 package - reducing PCB area by ~40% versus dual SO-8 solutions and eliminating enable-control complexity versus triple-channel variants.

FAQ
What is the operating supply voltage range for the MAX4222EEE?
The MAX4222EEE operates from a single 3.15V to 11V supply or dual ±1.575V to ±5.5V supplies. At 5V single supply, it delivers full 230MHz bandwidth and ±120mA output drive while consuming 5.5mA per channel. The input common-mode range extends 100mV beyond VEE, supporting true ground-sensing in low-voltage systems.
Does the MAX4222EEE have an enable/disable function?
No, the MAX4222EEE does not include an enable/disable feature. Unlike the MAX4215 or MAX4219, it lacks an EN pin and cannot be placed in low-power shutdown mode. Its quiescent current remains fixed at 5.5mA per channel (22mA total) regardless of signal activity. Pins 6 and 11 (ENB/ENC) are No Connect and must be left floating or tied to VEE.
What package type is used for the MAX4222EEE?
The MAX4222EEE is supplied in a 16-pin QSOP package (5.3mm × 10.2mm, 0.635mm pitch), specified in the datasheet as "16 QSOP". This surface-mount package supports automated assembly, offers better thermal dissipation than SO-14 for quad-channel operation, and is pin-compatible with other MAX42xx QSOP variants like MAX4219EEE.
Can the MAX4222EEE drive 75Ω video cables directly?
Yes, the MAX4222EEE can drive 75Ω coaxial video cables directly. Its ±120mA output drive capability allows it to sustain >2Vp-p into 75Ω loads at 5V supply, and its 0.03%/0.04° differential gain/phase error meets SMPTE standards for broadcast video. For optimal impedance matching, terminate the output with a 75Ω resistor to ground or use back-termination per typical application circuits.
How does the MAX4222EEE achieve its fixed gain configuration?
The MAX4222EEE achieves fixed gain using internal 500Ω precision thin-film resistors that form a closed-loop network. In noninverting mode (+2V/V), the inverting input is grounded; in inverting mode (-1V/V), the noninverting input is grounded. This eliminates external resistors, ensuring gain stability over temperature and time - critical for video fidelity where gain drift causes luminance variation.
