Product details
Overview
MAX4414ESA+T from Maxim Integrated is a single-channel, unity-gain stable, rail-to-rail output operational amplifier optimized for low-power, high-speed video and portable signal conditioning. It delivers 400MHz -3dB bandwidth, 200V/µs slew rate, and consumes only 1.6mA supply current per amplifier while operating from +2.7V to +5.5V. Its input common-mode range extends 100mV below ground and within 1.5V of VCC, enabling wide dynamic range in single-supply video line driver applications.
For engineers reviewing the MAX4414ESA+T datasheet, MAX4414ESA+T pinout, MAX4414ESA+T application, or MAX4414ESA+T equivalent, this op amp is selected for precision video buffering, baseband signal amplification, and low-voltage ADC input conditioning where ultra-low distortion (–93dBc SFDR at 5MHz), differential gain error ≤0.03%, and rail-to-rail output swing are critical design requirements.
Technical Context
The MAX4414ESA+T employs a voltage-feedback architecture with internal unity-gain compensation, enabling stable operation at AV = +1V/V without external compensation. Its output stage uses demand-driven current biasing and internal feedback to maintain low open-loop output impedance (<0.5Ω at 1MHz) and minimize load-dependent gain variation.
It features ground-sensing inputs (common-mode range: VEE –0.1V to VCC –1.5V) and rail-to-rail outputs capable of swinging within 105mV of either supply rail under 1kΩ load. Stability with capacitive loads requires an isolation resistor (e.g., 22Ω) to suppress peaking and oscillation - not inherent unity-gain drive capability.

Pinout & Package
MAX4414ESA+T is housed in an 8-pin SO (Small Outline) package, RoHS-compliant and rated for –40°C to +85°C operation. The package provides standard SOIC footprint compatibility and thermal performance up to 471mW at +70°C ambient.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | N.C. | No internal connection; must be left unconnected or tied to ground per layout best practice. |
| 2 | IN– | Inverting input terminal; high-impedance node (16MΩ typical) sensitive to PCB parasitic capacitance. |
| 3 | IN+ | Noninverting input terminal; supports common-mode voltages down to VEE –0.1V for true ground sensing. |
| 4 | VEE | Negative supply pin; connected to ground in single-supply operation; must be bypassed with 0.1µF capacitor. |
| 5 | N.C. | No internal connection; electrically isolated - avoid routing signals or power near this pad. |
| 6 | OUT | Amplifier output; rail-to-rail capable; requires series isolation resistor (e.g., 22Ω) when driving >15pF capacitive loads. |
| 7 | N.C. | No internal connection; no electrical function - treat as floating or ground per EMI mitigation strategy. |
| 8 | VCC | Positive supply pin; operates from +2.7V to +5.5V; requires local 0.1µF ceramic bypass to VEE. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4415ESA+T | Compensated for minimum gain of +5V/V; 150MHz bandwidth, 470V/µs slew rate - higher slew but narrower bandwidth than MAX4414ESA+T. | Preferred for fixed-gain video gain blocks or IF amplifiers requiring >400V/µs transient response at moderate bandwidth. | Select MAX4415ESA+T when closed-loop gain ≥5V/V is fixed and faster edge rates outweigh bandwidth loss. |
| ADA4891-1ARJZ-R7 | Unity-gain stable; 225MHz bandwidth, 170V/µs slew rate; 3.2mA supply current; wider input common-mode range (to VEE –0.2V). | Better suited for industrial sensor interfaces requiring extended input range and higher ESD tolerance (±2kV HBM). | Choose ADA4891-1ARJZ-R7 for harsh-environment designs where robustness and rail-to-rail input exceed MAX4414ESA+T's capabilities. |
Compared with MAX4415ESA+T and ADA4891-1ARJZ-R7, the MAX4414ESA+T uniquely balances 400MHz bandwidth, 1.6mA supply current, and 0.03% differential gain error - making it the optimal choice for battery-constrained, broadcast-grade video line drivers where both speed and fidelity are non-negotiable.

FAQ
What is the maximum capacitive load the MAX4414ESA+T can drive without oscillation?
The MAX4414ESA+T is specified to drive up to 120pF without sustained oscillations when properly bypassed and laid out. However, for reliable stability with reactive loads (e.g., coaxial cables or ADC inputs), Maxim recommends using a 22Ω isolation resistor in series with the output. This configuration suppresses peaking and ensures monotonic step response even with >150pF effective load capacitance - a requirement confirmed in the MAX4414ESA+T Typical Operating Characteristics (Figure MAX4414 toc05).
Does the MAX4414ESA+T support true rail-to-rail input operation?
No, the MAX4414ESA+T does not feature rail-to-rail input. Its input common-mode voltage range is specified from VEE –0.1V to VCC –1.5V - meaning it senses down to 100mV below ground but cannot accept signals within 1.5V of the positive rail. This ground-sensing capability enables single-supply interfacing with grounded sensors, but high-side signal monitoring requires external level shifting. This limitation is explicitly defined in the DC Electrical Characteristics table on page 2 of the MAX4414ESA+T datasheet.
Can the MAX4414ESA+T be used in a gain-of-ten configuration?
No - the MAX4414ESA+T is unity-gain stable and internally compensated for AV ≥ +1V/V only. Attempting to use it in a gain-of-ten configuration will result in instability, overshoot, and potential oscillation due to insufficient phase margin. For gain-of-ten applications, the pin-compatible MAX4415ESA+T (compensated for AV ≥ +5V/V) or MAX4417ESA+T should be selected instead, as confirmed in the Selector Guide table on page 1 of the MAX4414–MAX4419 datasheet.
What is the power-up settling behavior of the MAX4414ESA+T?
The MAX4414ESA+T achieves 1% output settling in 1.2µs after power supply ramp-up (VCC from 0V to +5V), as measured under standard test conditions (Figure MAX4414 toc41). This fast power-up time supports duty-cycled operation in portable instruments and enables synchronized wake-up with ADC or FPGA logic. The parameter is guaranteed over temperature and supply voltage (–40°C to +85°C, +2.7V to +5.5V) and is independent of output loading for resistive loads ≤10kΩ.
How does the MAX4414ESA+T perform in video applications compared to legacy op amps like the LMH6629?
The MAX4414ESA+T delivers significantly lower differential gain/phase error (0.03%/0.15° vs. LMH6629's 0.05%/0.3°) and lower supply current (1.6mA vs. 12.5mA) while maintaining competitive bandwidth (400MHz vs. 650MHz). Its –93dBc SFDR at 5MHz exceeds the LMH6629's –85dBc, making it superior for battery-powered NTSC/PAL video line drivers where power efficiency and color fidelity are prioritized over absolute bandwidth ceiling.
