Product details
Overview
The MAX4218EEE+ from Maxim Integrated is a triple, unity-gain-stable, rail-to-rail output operational amplifier with individual enable inputs per channel, designed for high-speed video and instrumentation signal conditioning. It delivers 200MHz -3dB bandwidth, 600V/µs slew rate, and 0.02%/0.02° differential gain/phase error while operating from a single 3.3V–10V supply or dual ±1.65V–±5V supplies. Its 400µA shutdown current and high-impedance disabled outputs make it suitable for multiplexed analog routing in CCD imaging systems.
For engineers reviewing the MAX4218EEE+ datasheet, MAX4218EEE+ pinout, MAX4218EEE+ application, or MAX4218EEE+ equivalent, key selection criteria include its triple-channel architecture with independent ENA/ENB/ENC control, QSOP-16 package footprint, 200MHz small-signal bandwidth (distinct from MAX4212/MAX4213's 300MHz), rail-to-rail output swing within 50mV of rails, and verified performance in NTSC video line driving at 150Ω load.
Technical Context
The MAX4218EEE+ employs voltage-feedback architecture enhanced with current-feedback techniques to achieve high slew rate and wide bandwidth while maintaining unity-gain stability. Its input stage supports common-mode voltages extending 200mV below VEE and up to 2.25V below VCC, enabling ground-sensing operation in single-supply configurations.
Each amplifier features an independent enable input (ENA, ENB, ENC) that reduces quiescent current to 400µA and raises output impedance to 35kΩ in the disabled state. The device uses local feedback around the output stage to sustain ±100mA drive capability while limiting total supply current to 5.5mA per amplifier under active conditions.

Pinout & Package
The MAX4218EEE+ is housed in a 16-pin QSOP package (3.9mm × 4.9mm, 0.635mm pitch), optimized for high-density PCB layouts while maintaining thermal and electrical performance.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | ENA | Enable input for Amplifier A - logic-high enables operation; logic-low disables amplifier and places output in high-Z state |
| 2 | INB+ | Noninverting input of Amplifier B - accepts differential or single-ended signals with extended common-mode range |
| 3 | INB− | Inverting input of Amplifier B - used with INB+ for differential gain configuration or as standalone inverting input |
| 4 | VEE | Negative power supply or ground - reference for all three amplifiers; supports single-supply operation when tied to GND |
| 5 | VCC | Positive power supply - supplies bias and output drive for all channels; bypassing with 0.1µF capacitor required |
| 6 | ENB | Enable input for Amplifier B - independently controls power state of second amplifier |
| 7 | ENC | Enable input for Amplifier C - allows selective activation of third channel for dynamic power management |
| 8 | OUTA | Output of Amplifier A - rail-to-rail capable, ±100mA drive, high-impedance when ENA = low |
| 9 | INA− | Inverting input of Amplifier A - forms feedback node in inverting configurations; matched to INA+ for precision gain setting |
| 10 | INA+ | Noninverting input of Amplifier A - supports DC-coupled inputs down to VEE − 0.2V |
| 11 | OUTB | Output of Amplifier B - electrically isolated from OUTA/OUTC during disable; 2pF disabled capacitance minimizes crosstalk |
| 12 | INC+ | Noninverting input of Amplifier C - shares same input structure and noise performance as other channels |
| 13 | INC− | Inverting input of Amplifier C - supports unity-gain or gain-of-two configurations with internal compensation |
| 14 | OUTC | Output of Amplifier C - maintains 0.1dB gain flatness up to 50MHz for composite video applications |
| 15 | IND− | No connection - not internally bonded; must be left open or grounded per layout best practices |
| 16 | IND+ | No connection - unused pin in MAX4218; no internal connection; tie to ground if needed for mechanical stability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4216ESA+ | Dual-channel version in SO-8; no individual enable per channel - shared enable only | Lacks per-amplifier shutdown; unsuitable for asymmetric power management in multi-path systems | Select when only two channels are needed and global enable suffices; lower pin count saves board space |
| THS3201CDGNR | Single-channel, 1.8GHz bandwidth, no rail-to-rail output; requires ±5V supply minimum | Higher bandwidth but incompatible with 3.3V-only systems and lacks output swing near rails | Choose for ultra-wideband RF applications where speed outweighs voltage compliance and channel count |
Compared with MAX4216ESA+, the MAX4218EEE+ offers triple-channel density and per-amplifier enable control essential for adaptive power routing; versus THS3201CDGNR, it trades raw bandwidth for rail-to-rail operation, lower supply voltage support, and integrated enable functionality - making it superior for battery-powered video and instrumentation interfaces.

FAQ
What is the maximum operating supply voltage for the MAX4218EEE+?
The MAX4218EEE+ supports a maximum supply voltage of 12V across VCC to VEE, with recommended operation from 3.3V to 10V single supply or ±1.65V to ±5V dual supplies. Absolute maximum rating is 12V; exceeding this risks permanent damage. Operation at 10V is fully characterized and validated in the datasheet for all AC and DC parameters including bandwidth and distortion.
Does the MAX4218EEE+ support true rail-to-rail input operation?
The MAX4218EEE+ does not support rail-to-rail input - its input common-mode range extends from (VEE − 0.2V) to (VCC − 2.25V). This "ground-sensing" input allows operation with inputs at or slightly below ground in single-supply systems, but does not accept signals at the positive rail. The output, however, is rail-to-rail, swinging within 50mV of both VCC and VEE.
How does the enable function affect output impedance in the MAX4218EEE+?
When any enable input (ENA, ENB, or ENC) is driven low, the corresponding amplifier's output transitions to a high-impedance state with typical resistance of 35kΩ and capacitance of only 2pF. This behavior is explicitly characterized in the datasheet and enables clean analog multiplexing without loading adjacent channels - a key advantage over op amps with undefined or resistive-disabled outputs.
Can the MAX4218EEE+ drive a 50Ω coaxial cable directly?
Yes, the MAX4218EEE+ can drive a 50Ω coaxial cable directly when properly terminated: use a series 24Ω resistor (RF) in the feedback path for unity-gain configuration, and terminate the far end with 50Ω to ground. This matches characteristic impedance, prevents reflections, and maintains 200MHz bandwidth and <0.02° phase error - as verified in the Typical Operating Characteristics section of the datasheet.
What is the small-signal -3dB bandwidth of the MAX4218EEE+ and how does it differ from the MAX4212/MAX4213?
The MAX4218EEE+ has a small-signal -3dB bandwidth of 200MHz, confirmed in the AC Electrical Characteristics table and Small-Signal Gain vs. Frequency plots. This is distinct from the 300MHz bandwidth of the MAX4212/MAX4213 - a family-level differentiation based on channel count and internal compensation. The MAX4218EEE+'s 200MHz rating applies across all three channels under identical test conditions (AVCL = +1, VOUT = 20mVP-P).
