Product details
Overview
The MAX4020ESD+ from Analog Devices is a quad, unity-gain-stable, rail-to-rail output operational amplifier optimized for high-speed video and communications signal conditioning. It delivers 150MHz -3dB bandwidth, 600V/μs slew rate, ±120mA output drive, and operates from a single 3.3V to 10V supply or dual ±1.65V to ±5V supplies. Its enable inputs (ENA–ENB–ENC–END) support independent shutdown per channel, reducing quiescent current to 400μA per amplifier and placing outputs in high-impedance state - ideal for video multiplexing in surveillance systems.
For engineers reviewing the MAX4020ESD+ datasheet, MAX4020ESD+ pinout, MAX4020ESD+ application, or MAX4020ESD+ equivalent, key selection criteria include its 14-pin SO package, quad-channel disable capability, 150MHz bandwidth at AVCL = 1, differential gain/phase error of 0.02%/0.02°, and compatibility with 50Ω/75Ω video line driving architectures.
Technical Context
The MAX4020ESD+ employs voltage-feedback architecture enhanced with current-feedback techniques to achieve wide bandwidth and fast transient response while maintaining stability at unity gain. 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–END), allowing selective channel activation. When disabled, output impedance exceeds 28kΩ with only 2pF capacitance, minimizing crosstalk and loading in multiplexed video routing applications - confirmed by AC electrical characterization at f = 10MHz and RL = 50Ω.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 150MHz at AVCL = 1, VOUT = 20mVP-P - ensures full NTSC/PAL video bandwidth without attenuation |
| Slew Rate | 600V/μs - supports clean 2V step transitions in under 45ns, critical for HD video pulse fidelity |
| Output Drive | ±120mA into 20Ω load - drives 50Ω/75Ω transmission lines directly without external buffers |
| Differential Gain/Phase | 0.02% / 0.02° at NTSC, RL = 150Ω - preserves color fidelity in broadcast-quality video systems |
| Supply Range | Single 3.3V to 10V or dual ±1.65V to ±5V - enables flexible integration in low-voltage embedded and industrial video hardware |
| Quiescent Current (enabled) | 5.5mA per amplifier - balances speed and power efficiency in multi-channel designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4018ESD+ | Triple-channel version in same 14-pin SO package; identical AC specs but lacks fourth amplifier and END pin | Not suitable for 4-input video mux; requires redesign if fourth channel is essential | Select MAX4018ESD+ only when exactly three channels are needed and board space must be conserved |
| THS4631D | Single-channel, 350MHz bandwidth, no enable function; higher supply current (11.5mA) | Requires four separate ICs and external logic for channel enable - increases BOM count and layout complexity | Choose THS4631D only when >200MHz bandwidth is mandatory and per-channel shutdown is unnecessary |
Compared with MAX4018ESD+, MAX4020ESD+ adds a fourth amplifier and dedicated END pin for complete quad-channel control; compared with THS4631D, it integrates four channels with enable logic in one 14-pin SO package, reducing PCB area by ~65% and eliminating inter-device timing skew.

FAQ
What is the operating temperature range for the MAX4020ESD+?
The MAX4020ESD+ is rated for operation from -40°C to +85°C ambient temperature. This industrial-grade range is validated per Analog Devices' absolute maximum ratings and DC/AC electrical specifications, ensuring reliable performance in surveillance enclosures, portable test equipment, and factory-floor video interfaces where thermal margins are constrained.
Does the MAX4020ESD+ support single-supply operation?
Yes, the MAX4020ESD+ supports true single-supply operation from 3.3V to 10V. Its input common-mode range extends 200mV below VEE (ground), and outputs swing to within 60mV of both rails - enabling ground-referenced inputs and full-rail output utilization in 3.3V or 5V systems without level-shifting circuitry.
What is the purpose of the EN pins on the MAX4020ESD+?
The EN pins (ENA, ENB, ENC, END) provide independent digital control over each of the four amplifiers. When pulled low, they reduce quiescent current per channel to 400μA and place the corresponding output in a high-impedance state (28–35kΩ, <2pF). This enables dynamic power management and analog multiplexing without external switches or relays.
Can the MAX4020ESD+ drive 75Ω video loads directly?
Yes, the MAX4020ESD+ can drive 75Ω video loads directly. Its ±120mA output current capability and 6Ω typical open-loop output impedance allow stable operation into 75Ω with minimal gain error or distortion - verified in typical operating circuits using RTIN/RTO networks for 75Ω termination and confirmed by harmonic distortion measurements at 5MHz with RL = 75Ω.
How does the MAX4020ESD+ compare to the MAX4012 in terms of bandwidth?
The MAX4020ESD+ has a 150MHz -3dB bandwidth (AVCL = 1), while the MAX4012 achieves 200MHz. This difference arises from internal compensation trade-offs: the MAX4020ESD+ prioritizes quad-channel integration and enable functionality in a 14-pin SO package, whereas the MAX4012 is a single-channel device optimized purely for maximum speed in SOT23-5 or SO-8 form factors.
