Product details
Overview
The MAX4012ESA+ from Analog Devices is a single, unity-gain-stable, rail-to-rail output operational amplifier optimized for high-speed video and communications signal conditioning. It delivers 200MHz -3dB bandwidth, 600V/μs slew rate, and ±120mA output drive while consuming only 5.5mA quiescent current from a 3.3V–10V single supply - enabling use in battery-powered instrumentation and 5V video line drivers.
For engineers reviewing the MAX4012ESA+ datasheet, MAX4012ESA+ pinout, MAX4012ESA+ application, or MAX4012ESA+ equivalent, key selection criteria include its rail-to-rail output swing (within 60mV of rails), input common-mode range extending beyond ground, low 0.02% differential gain error, and SO-8 package compatibility with space-constrained analog front-ends.
Technical Context
The MAX4012ESA+ employs voltage-feedback architecture enhanced with current-feedback techniques to achieve wide bandwidth and fast settling (45ns to 0.1%). Its input stage supports common-mode voltages down to VEE − 0.2V and up to VCC − 2.25V, making it suitable for ground-sensing single-supply systems.
It features internal unity-gain compensation and requires only a 24Ω feedback resistor in unity-gain configuration to optimize AC response. Output stage local feedback ensures low open-loop output impedance (~8Ω) and demand-driven biasing for robust ±120mA drive into 20Ω loads without exceeding 7mA total supply current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 200MHz - enables full HD video signal amplification without attenuation at baseband |
| Slew Rate | 600V/μs - supports clean 2V step transitions in under 4ns, critical for fast pulse fidelity |
| Supply Current | 5.5mA typical - allows integration into low-power portable instruments without thermal derating |
| Output Drive | ±120mA - drives 50Ω video lines or 75Ω coaxial cables directly without external buffers |
| Input CM Range | VEE − 0.2V to VCC − 2.25V - accommodates ground-referenced inputs in 3.3V/5V systems |
| Output Swing | VCC − 0.06V / VEE + 0.06V (RL = 2kΩ) - maximizes dynamic range in single-supply ADC interface applications |
| Differential Gain/Phase | 0.02% / 0.02° - meets broadcast-grade NTSC/PAL video linearity requirements |
Pinout & Package
The MAX4012ESA+ is housed in an 8-pin SO (Small Outline) package, RoHS-compliant and rated for operation from −40°C to +85°C.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | N.C. | No internal connection; may be left floating or tied to ground for mechanical stability |
| 2 | IN− | Inverting input terminal; accepts differential or single-ended signals with rail-to-rail common-mode range |
| 3 | IN+ | Noninverting input terminal; supports input voltages below ground in single-supply configurations |
| 4 | VEE | Negative power supply or ground reference; defines lower rail for input/output swing |
| 5 | OUT | Amplifier output; delivers rail-to-rail voltage swing and ±120mA current into reactive or resistive loads |
| 6 | N.C. | No internal connection; no electrical function; PCB layout may treat as thermal pad or ground tie |
| 7 | VCC | Positive power supply; operates from 3.3V to 10V single supply or ±1.65V to ±5V dual supplies |
| 8 | N.C. | No internal connection; electrically isolated; recommended to connect to ground for EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 60mV of VCC and VEE under 2kΩ load - preserves >97% of available voltage headroom |
| Ground-sensing input | Common-mode range extends 200mV below VEE - enables direct interfacing to 0V-referenced sensors or DACs |
| Low distortion at 5MHz | −75dB THD and −78dBc SFDR - maintains signal integrity in high-frequency video and RF IF stages |
| Unity-gain stable | Internally compensated with 24Ω feedback resistor requirement - eliminates external compensation components |

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 |
|---|---|---|---|
| MAX4012EUK+ | Same core amplifier specs, but in 5-pin SOT23 package - smaller footprint, higher thermal resistance (7.1mW/°C derating) | Better suited for ultra-compact PCBs where board area is constrained more than thermal budget | Select MAX4012EUK+ when minimizing footprint is critical and power dissipation remains ≤571mW at +70°C ambient |
| AD8057ARZ | 225MHz bandwidth, 1100V/μs slew rate, but higher 8.5mA quiescent current and no guaranteed rail-to-rail output swing | Preferred in high-fidelity oscilloscope front-ends where speed outweighs power efficiency | Choose AD8057ARZ when >200MHz bandwidth and faster settling are required, and 3.3V rail-to-rail output is not mandatory |
Compared with MAX4012EUK+, the MAX4012ESA+ offers superior thermal management in SO-8 format; compared with AD8057ARZ, it trades marginal speed for significantly lower supply current and guaranteed rail-to-rail output compliance in 3.3V–5V systems.

FAQ
What is the maximum supply voltage for the MAX4012ESA+?
The MAX4012ESA+ supports a supply voltage range of 3.15V to 11.0V between VCC and VEE. In single-supply operation, this corresponds to 3.3V to 10V referenced to ground. Absolute maximum ratings specify 12V, but sustained operation above 11V risks reliability degradation per Analog Devices' specifications.
Does the MAX4012ESA+ have a shutdown or enable pin?
No, the MAX4012ESA+ does not include an enable (EN_) pin. That feature is exclusive to the MAX4018 and MAX4020 variants. The MAX4012ESA+ operates continuously when powered; power-down must be implemented externally via supply switching or series FET control.
Can the MAX4012ESA+ drive a 50Ω load effectively?
Yes, the MAX4012ESA+ delivers ±120mA output current and is explicitly characterized driving 50Ω loads. Its 600V/μs slew rate and 200MHz bandwidth ensure minimal distortion and fast settling when configured as a unity-gain line driver with proper 24Ω feedback and termination.
What is the input offset voltage specification for the MAX4012ESA+?
The MAX4012ESA+ has a typical input offset voltage of 4mV, with a maximum of 20mV over temperature (−40°C to +85°C). This value is guaranteed by design and tested per Analog Devices' DC Electrical Characteristics table, ensuring predictable DC accuracy in precision gain stages.
Is the MAX4012ESA+ pin-compatible with other op amps in the same package?
No, the MAX4012ESA+ uses a nonstandard SO-8 pinout: pins 1, 6, and 8 are N.C., with IN−, IN+, VEE, OUT, and VCC occupying pins 2, 3, 4, 5, and 7 respectively. It is not pin-compatible with generic SO-8 op amps like the LM358 or AD8057, which follow industry-standard pin assignments.
