Product details
Overview
The MAX4220ESD from Maxim Integrated is a quad, rail-to-rail output, voltage-feedback operational amplifier with enable control, designed for high-speed video and RF signal conditioning in single-supply systems. It delivers 200MHz -3dB bandwidth, 600V/µs slew rate, and 0.02%/0.02° differential gain/phase error, operating from 3.3V to 10V supply. Its 14-pin SO package supports video line driving, ADC interface, and multiplexed analog routing applications.
For engineers reviewing the MAX4220ESD datasheet, MAX4220ESD pinout, MAX4220ESD application, or MAX4220ESD equivalent, this page provides verified electrical specifications, disable-state output impedance (35kΩ), AC performance data (SFDR = –78dBc at 5MHz), thermal stability across –40°C to +85°C, and validated alternative options for video amplifier replacement scenarios.
Technical Context
The MAX4220ESD employs current-feedback techniques within a voltage-feedback architecture to achieve unity-gain stability with 600V/µs slew rate and 200MHz small-signal bandwidth. Its input stage accepts common-mode voltages down to VEE – 0.2V and up to VCC – 2.25V, enabling ground-sensing operation in single-supply configurations.
All four amplifiers feature independent enable inputs (ENA, ENB, ENC, END), each reducing quiescent current to 400µA and placing the corresponding output into high-impedance state (ROUT(OFF) = 20–35kΩ). The device maintains low distortion (–75dB THD, –78dBc SFDR) and 50MHz 0.1dB gain flatness under AVCL = 1, supporting NTSC-compliant video signal integrity.

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 |
|---|---|---|---|
| MAX4218ESD | Same quad architecture, 14-pin SO package, but lacks individual enable inputs (shared EN pin only) | Not suitable for per-channel power gating; requires global enable/disable sequencing | Select MAX4220ESD when independent amplifier control is required for dynamic power management |
| THS4271DR | Single-channel, 1.3GHz bandwidth, no enable function; higher supply current (11.5mA) | Requires four separate ICs for quad functionality; no integrated disable mode for multiplexing | Choose THS4271DR only for ultra-wideband (>500MHz) single-channel needs where MAX4220ESD's 200MHz is insufficient |
Compared with MAX4218ESD and THS4271DR, the MAX4220ESD uniquely combines quad-channel integration, per-amplifier enable control, 200MHz bandwidth, and <2pF disabled output capacitance-making it optimal for space-constrained, low-power video routing and instrumentation systems requiring selective channel activation.

FAQ
What is the maximum operating supply voltage for the MAX4220ESD?
The MAX4220ESD supports an absolute maximum supply voltage of 12V (VCC to VEE), with recommended operating range from 3.15V to 11.0V. At 5V supply, it delivers full 200MHz bandwidth and 600V/µs slew rate while maintaining rail-to-rail output swing within 50mV of both rails. Exceeding 11.0V risks parametric degradation or reliability impact.
Does the MAX4220ESD support true single-supply operation with input signals extending below ground?
Yes, the MAX4220ESD supports true single-supply operation with input common-mode voltage extending to VEE – 0.2V. When VEE = 0V (ground), the input accepts signals down to –200mV, enabling DC-coupled interfacing with sensors or transducers that swing slightly negative. This ground-sensing capability eliminates the need for level-shifting circuitry in many instrumentation designs.
How does the enable function affect output behavior in the MAX4220ESD?
When any enable input (e.g., ENA) is driven low ( Yes, the MAX4220ESD can directly drive 75Ω video loads in unity-gain configuration using the recommended 24Ω series feedback resistor (RF) per channel. Its ±100mA output drive, 200MHz bandwidth, and 0.02%/0.02° differential gain/phase error meet SMPTE 259M and ITU-R BT.601 requirements for baseband SD/HD video distribution without additional buffering or termination circuitry. The MAX4220ESD maintains stable quiescent current (5.5–7.0mA enabled) and input bias current (<20µA) across –40°C to +85°C, as verified in Figures 31–35 of the datasheet. Its small-signal bandwidth remains ≥180MHz and THD stays ≤–75dB at +85°C, confirming robust performance in industrial and automotive cabin environments without derating.Can the MAX4220ESD drive 75Ω video loads directly without external components?
What is the thermal performance of the MAX4220ESD over its full operating temperature range?
