Product details
Overview
MAX4219EEE from Maxim Integrated is a triple-channel, high-speed, closed-loop rail-to-rail buffer IC with enable functionality, configured for fixed gains of +2V/V (noninverting) or −1V/V (inverting). It delivers 230MHz −3dB bandwidth, 600V/µs slew rate, ±120mA output drive, and operates from a single 3.15V–11V supply. It is used in video routing and switching systems requiring precise gain stability and low distortion.
For engineers reviewing the MAX4219EEE datasheet, MAX4219EEE pinout, MAX4219EEE application, or MAX4219EEE equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options - all grounded in the official MAX4219 datasheet (Rev 1, 8/01) and Maxim's product documentation.
Technical Context
The MAX4219EEE integrates three independent voltage-feedback buffers using internal 500Ω precision resistors to fix closed-loop gain at +2V/V or −1V/V without external components. Its current-feedback architecture enables high slew rate and wide bandwidth while maintaining rail-to-rail output swing and input common-mode range extending 100mV beyond VEE.
Each channel features an independent enable input (ENA/ENB/ENC), reducing quiescent current to 400µA per buffer when disabled. The device exhibits low differential gain/phase error (0.03%/0.04°), −72dBc SFDR at 5MHz, and 10nV/√Hz input voltage noise - characteristics critical for NTSC video signal integrity and high-fidelity analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 230MHz −3dB (small-signal); ensures full NTSC/PAL video bandwidth preservation without attenuation |
| Slew Rate | 600V/µs; supports fast transient response for composite video sync pulses and digital video edges |
| Output Drive | ±120mA; drives 50Ω/75Ω coaxial cables directly or sustains 150Ω loads at full rail-to-rail swing |
| Supply Current | 5.5mA per buffer (active), 400µA per buffer (disabled); enables dynamic power gating in multi-channel systems |
| Differential Error | 0.03% gain error / 0.04° phase error (NTSC, RL = 150Ω); preserves color fidelity in broadcast-grade video paths |
| Input Noise | 10nV/√Hz voltage noise, 1.3pA/√Hz current noise; minimizes SNR degradation in low-level analog signal chains |
| Enable Logic | EN_ pin thresholds: VIH ≥1.6V, VIL ≤0.075V (relative to VEE); compatible with 3.3V/5V logic control without level shifters |
Pinout & Package
MAX4219EEE is housed in a 16-pin QSOP package (5.03mm × 4.78mm, 0.65mm pitch), optimized for space-constrained video interface PCBs. Pin functions are electrically isolated per channel and support independent enable control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | INA−, INA+, INB−, INB+ | Noninverting/inverting inputs for Channels A and B; 500Ω internal feedback resistors set fixed gain |
| 5, 6, 7, 8 | INC−, INC+, OUTA, OUTB | Inverting/noninverting inputs and outputs for Channel C and A/B outputs; rail-to-rail swing to VCC/VEE |
| 9, 10, 11 | OUTC, ENA, ENB | Channel C output and per-channel enable inputs; active-low logic disables buffer and reduces ICC to 400µA |
| 12, 13, 14, 15 | ENC, VEE, VCC, N.C. | Channel C enable, negative/positive supplies, and no-connect pin; VEE serves as ground in single-supply operation |
| 16 | N.C. | No internal connection; must be left floating or tied to ground per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Fixed Closed-Loop Gain | +2V/V or −1V/V via internal 500Ω resistors - eliminates external resistor matching errors and board area |
| Rail-to-Rail Output Swing | Drives 2kΩ load within 60mV of rails; maintains >3.8Vp-p swing into 150Ω for full NTSC luminance/chrominance headroom |
| Low Distortion Performance | −72dBc SFDR and −71dB THD at 5MHz - meets broadcast video linearity requirements without post-compensation |
| Independent Channel Enable | Three separate EN_ inputs allow selective shutdown of unused channels, cutting system-level quiescent power by >85% |
| Input Common-Mode Range | Extends to VEE −100mV - enables ground-referenced input signals in single-supply 3.3V/5V systems without level shifting |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, gain-of-2 buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4215ESA | Single-channel, 8-pin SO package; identical electrical specs but no multi-channel integration | Requires three separate ICs and PCB area for same functionality as MAX4219EEE | Select when board space allows discrete channel implementation or when only one buffer is needed per design |
| THS3201DGN | Single-channel, 8-pin MSOP; 440MHz bandwidth, 3000V/µs slew rate, but no internal gain-setting resistors or enable feature | Requires external 500Ω resistors for gain-of-2; lacks shutdown mode and has higher 12.5mA ICC | Select when ultra-wide bandwidth (>400MHz) is mandatory and external gain configuration is acceptable |
Compared with MAX4215ESA, MAX4219EEE saves >60% board area and simplifies BOM by integrating three matched buffers; compared with THS3201DGN, it trades raw speed for integrated gain, lower power, and enable control - making it optimal for space- and power-sensitive video routing.

FAQ
What is the operating supply voltage range for MAX4219EEE?
The MAX4219EEE operates from a single 3.15V to 11V supply or dual ±1.575V to ±5.5V supplies. At VCC = 5V and VEE = 0V, it delivers full 230MHz bandwidth and rail-to-rail output swing. The input common-mode range extends from VEE −100mV to VCC −2.25V, supporting ground-referenced inputs in 3.3V/5V systems. This flexibility makes MAX4219EEE suitable for both portable and mains-powered video equipment.
Does MAX4219EEE support inverting and noninverting configurations?
Yes, MAX4219EEE supports both configurations using its internal 500Ω resistors. For noninverting gain of +2V/V, tie the inverting input (e.g., INA−) to ground and apply signal to the noninverting input (INA+). For inverting gain of −1V/V, ground INA+ and apply signal to INA−. The MAX4219EEE datasheet confirms these configurations are factory-trimmed and do not require external resistors - ensuring consistent gain accuracy across temperature and unit-to-unit.
What is the shutdown current of MAX4219EEE and how is it controlled?
When the enable pin (e.g., ENA) is pulled to VEE, MAX4219EEE reduces its quiescent supply current to 400µA per enabled buffer. Each of the three channels has an independent enable input (ENA, ENB, ENC), allowing selective shutdown. The logic threshold is VIL ≤0.075V above VEE, making it compatible with standard 0V/3.3V or 0V/5V control signals. This feature is verified in the AC Electrical Characteristics table of the MAX4219EEE datasheet under ISD parameter.
Can MAX4219EEE drive 75Ω video loads directly?
Yes, MAX4219EEE can drive 75Ω loads directly with minimal signal degradation. Tested at NTSC conditions (RL = 150Ω), it achieves 0.03% differential gain error and 0.04° phase error - well within broadcast specifications. When driving 75Ω, output swing remains >2.0Vp-p at 5MHz, and harmonic distortion stays below −70dBc. Layout best practices (e.g., microstrip routing, proper termination) are required to preserve this performance, as confirmed in the Applications Information section of the MAX4219EEE datasheet.
What package type is used for MAX4219EEE and what are its key mechanical dimensions?
MAX4219EEE uses a 16-pin QSOP package (5.03mm × 4.78mm body, 0.65mm lead pitch), per Maxim's package drawing QSOP.EPS. It has 16 gull-wing leads, 1.0mm maximum height, and is RoHS-compliant. The package supports reflow soldering per JEDEC J-STD-020 and is rated for −40°C to +85°C operation. Pin 16 is a no-connect; pins 12–15 serve as ENC, VEE, VCC, and N.C. - all defined in the Pin Configurations section of the MAX4219EEE datasheet.
