Analog Devices Inc./Maxim Integrated MAX4220EEE

Overview

MAX4220EEE from Maxim Integrated is a quad, unity-gain-stable, rail-to-rail output operational amplifier optimized for high-speed video and RF signal processing. It delivers 200MHz -3dB bandwidth, 600V/µs slew rate, 0.02% differential gain / 0.02° differential phase error, and operates from a single 3.3V–10V supply. It is used in video routing and switching systems requiring low-distortion, wide-bandwidth amplification with enable control.

For engineers reviewing the MAX4220EEE datasheet, MAX4220EEE pinout, MAX4220EEE application, or MAX4220EEE equivalent, key selection criteria include its quad-channel architecture with individual enable inputs (ENA/ENB/ENC/END), QSOP-16 package footprint, 200MHz small-signal bandwidth, rail-to-rail output swing within 50mV of rails, and 400µA shutdown current per amplifier-critical for multiplexed video signal paths and low-power instrumentation.

Technical Context

The MAX4220EEE employs voltage-feedback architecture enhanced with current-feedback techniques to achieve high slew rate and 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 systems.

Each of the four amplifiers features independent enable logic (active-high ENx pins) that reduces quiescent current to 400µA and raises output impedance to 35kΩ in disabled state. The device uses internal compensation and requires no external components for stable unity-gain operation when configured with a 24Ω feedback resistor.

Key Specifications

Pinout & Package

FAQ

What is the small-signal bandwidth of the MAX4220EEE and how is it verified?

The MAX4220EEE has a guaranteed 200MHz -3dB small-signal bandwidth under standard test conditions (VCC = 5V, RL = 100Ω, AVCL = +1, TA = +25°C). This value is measured and specified in the AC Electrical Characteristics table of the official Maxim datasheet (Rev 3, 10/03), confirmed across temperature and supply voltage ranges. It applies to all four amplifiers in the MAX4220EEE device.

Does the MAX4220EEE support single-supply operation and what is its input common-mode range?

Yes, the MAX4220EEE operates from a single 3.3V to 10V supply. Its input common-mode voltage range extends from (VEE − 0.2V) to (VCC − 2.25V), enabling true ground-sensing capability in single-supply configurations. For example, with VEE = 0V and VCC = 5V, inputs can range from −0.2V to +2.75V-critical for interfacing with grounded sensors or DAC outputs without level shifting.

How does the enable function work on the MAX4220EEE and what is its effect on output impedance?

The MAX4220EEE features four independent active-high enable inputs (ENA, ENB, ENC, END). When an ENx pin is driven low (≤ VCC − 2.6V), the corresponding amplifier enters shutdown mode, reducing quiescent current to 400µA and raising output impedance to 20–35kΩ. This high-Z state, combined with only 2pF disabled output capacitance, makes the MAX4220EEE ideal for analog video multiplexing without loading adjacent channels.

What is the differential gain and phase performance of the MAX4220EEE and why does it matter for video applications?

The MAX4220EEE delivers 0.02% differential gain error and 0.02° differential phase error under NTSC conditions (RL = 150Ω). These values ensure minimal color saturation and hue shift during analog video signal amplification-meeting broadcast-quality standards for RGB, YUV, and composite video distribution. This performance is measured and guaranteed in the datasheet's AC Electrical Characteristics table.

Can the MAX4220EEE drive 50Ω transmission lines directly, and what is its output current capability?

Yes, the MAX4220EEE can drive 50Ω loads directly. Each amplifier provides ±100mA continuous output current and maintains rail-to-rail swing within 50mV of VEE/VCC into 10kΩ. When driving 50Ω, it sustains full 2Vpp output at 5MHz with –75dB THD and –78dBc SFDR-verified in the Typical Operating Characteristics section (Figures 10–12) and AC specs table of the MAX4220EEE datasheet.
