Product details
Overview
MAX4218EEE from Maxim Integrated is a triple, unity-gain-stable, rail-to-rail output operational amplifier with enable/disable control, designed for high-speed video and instrumentation signal conditioning. It delivers 200MHz -3dB bandwidth, 600V/µs slew rate, and 400µA shutdown current while operating from 3.3V to 10V single supply - ideal for battery-powered video line drivers and ADC interface circuits.
For engineers reviewing the MAX4218EEE datasheet, MAX4218EEE pinout, MAX4218EEE application, or MAX4218EEE equivalent, key selection criteria include its triple-channel architecture with individual enable inputs (ENA/ENB/ENC), QSOP-16 package footprint, rail-to-rail output swing within 50mV of rails, low 10nV/√Hz input voltage noise, and verified performance in NTSC video routing systems requiring <0.02% differential gain error.
Technical Context
The MAX4218EEE employs voltage-feedback architecture enhanced with current-feedback techniques to achieve wide bandwidth and fast transient response. Its input stage supports common-mode voltages extending beyond VEE (to VEE − 0.2V) and up to VCC − 2.25V, enabling ground-sensing operation in single-supply systems.
Each of the three amplifiers features independent enable logic (active-high ENA/ENB/ENC), delivering high-output impedance (>20kΩ) and ultra-low quiescent current (400µA) when disabled. The device maintains stability in unity-gain configuration using an internal 24Ω feedback resistor and exhibits low distortion (−78dBc SFDR at 5MHz) suitable for precision analog signal paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4216ESA | Dual-channel version in SO-8; no enable pins; 200MHz bandwidth; 5.5mA active current | Lacks per-amplifier shutdown - unsuitable for dynamic channel gating in multiplexed systems | Select when board space is constrained and only two channels + no enable control are needed |
| THS3201CD | Single-channel, 1.8GHz bandwidth, 6000V/µs slew rate, no rail-to-rail output, no enable | Higher speed but incompatible supply range (±5V only); requires level-shifting for 3.3V systems | Select only for RF IF amplification above 500MHz where MAX4218EEE bandwidth is insufficient |
Compared with MAX4216ESA and THS3201CD, the MAX4218EEE uniquely combines triple-channel density, per-channel enable, rail-to-rail output, and 200MHz bandwidth in a single QSOP-16 package - making it optimal for compact, power-aware video signal routing where channel independence and low standby power are mandatory.

FAQ
What is the maximum operating supply voltage for MAX4218EEE?
The MAX4218EEE supports a total supply voltage (VCC to VEE) up to 12V DC, 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 in the datasheet for parameters including bandwidth, slew rate, and output swing.
Does MAX4218EEE support true rail-to-rail input common-mode range?
The MAX4218EEE input common-mode range extends from (VEE − 0.2V) to (VCC − 2.25V), enabling ground-sensing operation in single-supply configurations. It does not support full rail-to-rail input - the upper limit stops 2.25V below VCC. However, this range fully covers typical video and sensor signal levels referenced to ground or mid-supply.
How does the enable function behave on MAX4218EEE?
Each amplifier in the MAX4218EEE has its own active-high enable pin (ENA, ENB, ENC). When pulled low (≤VCC − 2.6V), the corresponding amplifier enters shutdown: supply current drops to 400µA and output impedance rises to 20–35kΩ. The output remains in high-impedance state with only 2pF capacitance - ideal for analog multiplexing without external switches.
Can MAX4218EEE drive 50Ω transmission lines directly?
Yes - the MAX4218EEE delivers ±100mA output current and maintains 200MHz bandwidth into 50Ω loads. For optimal 50Ω back-terminated driving, configure in unity-gain mode with the internal 24Ω feedback resistor (as specified in Figure 1a). Output swing remains >4.9VP-P on 5V supply, meeting standard video line driver requirements.
What is the thermal performance of MAX4218EEE in QSOP-16 package?
In the 16-pin QSOP package, MAX4218EEE has a thermal resistance θJA of 8.3°C/W. At maximum ambient temperature (+85°C) and full 5.5mA per amplifier (16.5mA total), power dissipation is ~82.5mW, resulting in junction temperature rise of ~0.69°C - well within safe operating limits. Derating begins above +70°C at 8.3mW/°C.
