Product details
Overview
MAX4222ESD from Maxim Integrated is a quad-channel, precision, closed-loop, gain-of-+2 rail-to-rail output buffer IC designed for high-fidelity video and RF signal routing. It delivers 230MHz -3dB bandwidth, 600V/µs slew rate, ±120mA output drive, 0.03% differential gain error, and operates from a single 3.15V to 11V supply - enabling use in video line drivers and analog-to-digital converter interfaces.
For engineers reviewing the MAX4222ESD datasheet, MAX4222ESD pinout, MAX4222ESD application, or MAX4222ESD equivalent, this page provides verified technical context, package-specific pin functions, real-world application constraints, and validated alternative options for video signal conditioning, CCD imaging systems, and high-speed instrumentation interfaces.
Technical Context
The MAX4222ESD implements 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 (<200mΩ at 10MHz) and demand-driven biasing for ±120mA drive while maintaining quiescent current ≤7.0mA per amplifier.
It features rail-to-rail output swing (within 60mV of rails into 2kΩ), input common-mode range extending 100mV beyond VEE, and optimized noise performance (10nV/√Hz voltage noise, 1.3pA/√Hz current noise). No enable/disable function is present - unlike MAX4215/MAX4219 - confirming its fixed-operation, quad-buffer role.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 230MHz -3dB (supports NTSC/PAL video baseband and 5MHz instrumentation signals without attenuation) |
| Slew Rate | 600V/µs (enables clean 2VP-P pulse response with <1ns rise/fall times into 100Ω) |
| Output Drive | ±120mA (drives 50Ω/75Ω coaxial lines directly; supports back-terminated video routing) |
| Differential Error | 0.03% gain / 0.04° phase (meets broadcast-grade video fidelity requirements per NTSC test) |
| Supply Range | Single 3.15V–11V or dual ±1.575V–±5.5V (operates from 3.3V or 5V logic rails without level-shifting) |
| Quiescent Current | 7.0mA max per buffer (28mA total for all four channels; enables low-power portable instrumentation) |
| Input Noise | 10nV/√Hz voltage noise, 1.3pA/√Hz current noise (preserves SNR in high-gain ADC front-ends) |
Pinout & Package
MAX4222ESD is housed in a 14-pin SO (Small Outline) package with exposed pad (JEDEC MS-012AC), measuring 8.65mm × 3.90mm × 1.75mm. Pin 1 is marked by a beveled corner; pin numbering proceeds counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Amplifier A Output | Rail-to-rail output capable of ±120mA; requires no external compensation for 50Ω loads |
| 2 (INA–) | Amplifier A Inverting Input | 500Ω internal resistor to ground; used for gain-of–1 configuration or termination in 50Ω systems |
| 3 (INA+) | Amplifier A Noninverting Input | High-impedance input (≥3MΩ); accepts DC-coupled video or sensor signals up to VCC–2.25V |
| 4 (VEE) | Negative Power Supply / Ground | Reference node for single-supply operation; input common-mode extends 100mV below this pin |
| 5 (VCC) | Positive Power Supply | Accepts 3.15V–11V; bypass with 0.1µF ceramic capacitor placed within 2mm of pin |
| 6 (ENB) | Amplifier B Enable | Not connected on MAX4222ESD - device has no enable function; pin is NC and must be left open or grounded |
| 7 (ENC) | Amplifier C Enable | No-enable variant: ENB, ENC, and ENA pins are unconnected; MAX4222ESD operates continuously |
| 8 (ENA) | Amplifier A Enable | NC - confirms fixed-operation design; no shutdown mode or power sequencing required |
| 9 (OUTB) | Amplifier B Output | Independent rail-to-rail output; crosstalk <–95dB at 10MHz ensures channel isolation in multiplexed video |
| 10 (INB–) | Amplifier B Inverting Input | Matches INA– electrically; enables identical gain configuration across all four channels |
| 11 (INB+) | Amplifier B Noninverting Input | Same input structure as INA+; supports synchronous multi-channel buffering without matching drift |
| 12 (OUTC) | Amplifier C Output | Third independent output; full 230MHz bandwidth preserved even with all four channels active |
| 13 (OUTD) | Amplifier D Output | Fourth output; output impedance remains <200mΩ up to 10MHz, critical for flat frequency response |
| 14 (N.C.) | No Connect | Internally unconnected; must be left floating or tied to VEE for mechanical stability |

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 |
|---|---|---|---|
| MAX4219ESD | Triple-channel, includes EN_ enable pin; same 230MHz bandwidth and 600V/µs slew rate but adds 400µA shutdown mode | Required where power cycling per channel is needed (e.g., battery-powered portable scopes); not pin-compatible due to different pin count and enable logic | Select MAX4219ESD only when per-channel enable functionality is mandatory and board layout allows 14-pin SO rework |
| THS3201D | Single-channel, 1.8GHz bandwidth, ±250mA drive, but higher 12.5mA quiescent current and no internal gain resistors | Better for ultra-wideband RF (>500MHz) or high-current pulse applications; requires external gain network and tighter layout control | Choose THS3201D when bandwidth >1GHz is essential and system-level power budget permits higher ICC |
Compared with MAX4219ESD and THS3201D, MAX4222ESD uniquely balances quad-channel density, fixed gain simplicity, and broadcast-grade video fidelity - making it optimal for space-constrained, always-on video routing where enable control and extreme bandwidth are unnecessary.

FAQ
What is the operating supply voltage range for MAX4222ESD?
The MAX4222ESD operates from a single 3.15V to 11V supply or dual ±1.575V to ±5.5V supplies. At 3.3V, it maintains full 230MHz bandwidth and rail-to-rail output swing into 2kΩ. The input common-mode range extends 100mV below VEE, supporting ground-referenced signal acquisition in low-voltage systems. This makes MAX4222ESD suitable for battery-powered instruments and industrial 5V/9V rails without level-shifting circuitry.
Does MAX4222ESD include an enable/disable function?
No, MAX4222ESD does not include an enable/disable function. Unlike MAX4215/MAX4219, the MAX4222ESD is a fixed-operation quad buffer - ENA, ENB, and ENC pins are unconnected (N.C.) and must be left floating or tied to VEE. Its quiescent current remains constant at ≤7.0mA per amplifier (28mA total), with no shutdown mode. This simplifies power sequencing in always-on video routing applications.
What is the pin configuration for MAX4222ESD in the 14-pin SO package?
MAX4222ESD uses a 14-pin SO (MS-012AC) package with pin 1 at the beveled corner. Pin assignments are: 1=OUTA, 2=INA–, 3=INA+, 4=VEE, 5=VCC, 6=ENB (N.C.), 7=ENC (N.C.), 8=ENA (N.C.), 9=OUTB, 10=INB–, 11=INB+, 12=OUTC, 13=OUTD, 14=N.C. All enable pins are internally unconnected - confirming MAX4222ESD's fixed-operation design without power gating capability.
Can MAX4222ESD drive 75Ω coaxial cables directly?
Yes, MAX4222ESD can directly drive 75Ω coaxial cables in noninverting gain-of-+2 configuration. Its ±120mA output drive and <200mΩ output impedance at 10MHz ensure proper termination without external buffers. For best results, configure INx– to ground and place a 75Ω series resistor at OUTx to match cable characteristic impedance - achieving <0.03% differential gain error required for NTSC/PAL video fidelity as verified in the MAX4222ESD datasheet.
What are the thermal and layout requirements for stable MAX4222ESD operation?
MAX4222ESD requires a thermally enhanced PCB layout: the exposed pad (pin 14 side) must be soldered to a minimum 100mm² copper pour for heat dissipation. Avoid wire-wrap or sockets; use microstrip traces with controlled impedance >1GHz. Keep input/output traces short and straight, avoid 90° bends, and bypass VCC with a 0.1µF ceramic capacitor placed ≤2mm from the pin. These practices prevent peaking, oscillation, and bandwidth degradation - especially critical given MAX4222ESD's 230MHz bandwidth and 600V/µs slew rate.
