Product details
Overview
The MAX4012EUK from Maxim Integrated is a single, unity-gain-stable, rail-to-rail output operational amplifier optimized for high-speed video and instrumentation applications. It delivers 200MHz -3dB bandwidth, 600V/µs slew rate, and 5.5mA quiescent supply current while operating from a 3.3V to 10V single supply. Its input common-mode range extends beyond the negative rail (ground), and output swings within 60mV of both rails with a 2kΩ load - enabling full dynamic range in low-voltage, single-supply systems such as video line drivers and ADC interfaces.
For engineers reviewing the MAX4012EUK datasheet, MAX4012EUK pinout, MAX4012EUK application, or MAX4012EUK equivalent, key selection criteria include its SOT23-5 package footprint, rail-to-rail output drive capability (±120mA), low differential gain/phase error (0.02%/0.02°), and verified performance in NTSC video routing, battery-powered test equipment, and high-fidelity analog front-ends where signal integrity at >100MHz is critical.
Technical Context
The MAX4012EUK employs a voltage-feedback architecture enhanced with current-feedback techniques to achieve wide bandwidth and fast transient response without sacrificing stability. Its internal compensation ensures unity-gain stability, and it uses local feedback around the output stage to maintain low open-loop output impedance (<6Ω) and enable ±120mA output drive while limiting total supply current to ≤7mA.
The input stage supports common-mode voltages from (VEE − 0.2V) to (VCC − 2.25V), making it ground-sensing in single-supply operation. The output stage achieves rail-to-rail swing with <60mV headroom to each rail under 2kΩ load, and exhibits low harmonic distortion (−78dBc SFDR at 5MHz) and exceptional gain flatness (±0.1dB to 30MHz), confirming suitability for precision video and RF signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 200MHz - enables baseband video (NTSC/PAL) and broadband analog signal amplification up to 100MHz fundamental content. |
| Slew Rate | 600V/µs - supports clean 2V-step transitions in <45ns, critical for fast-settling video line drivers and pulse amplifiers. |
| Supply Current | 5.5mA typical - allows integration into power-constrained portable instruments and multi-channel video systems without thermal penalty. |
| Input Common-Mode Range | Extends 200mV below VEE - permits direct coupling of ground-referenced AC signals in single-supply configurations without level-shifting. |
| Output Swing | Within 60mV of VEE and VCC with 2kΩ load - maximizes usable signal swing (e.g., 4.9VP-P on 5V supply), improving SNR in ADC interface stages. |
| Differential Gain/Phase | 0.02%/0.02° - meets broadcast video fidelity requirements (SMPTE/ITU-R BT.601), ensuring minimal color distortion in surveillance and set-top box outputs. |
| Small-Signal Distortion | −78dBc SFDR at 5MHz - preserves signal purity in high-resolution data acquisition and communications receiver IF stages. |
Pinout & Package
The MAX4012EUK is housed in a 5-pin SOT23-5 package (JEDEC MO-178AA), measuring 2.9mm × 1.6mm × 1.1mm, with gull-wing leads and 0.95mm pitch. This ultra-compact outline supports high-density PCB layouts in space-limited video modules and portable instrumentation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VEE | Negative supply or ground reference; supports single-supply operation with input common-mode down to VEE − 0.2V. |
| 2 | IN− | Inverting input terminal; used with IN+ to configure standard op-amp topologies (inverting/noninverting amplifiers, filters). |
| 3 | IN+ | Noninverting input terminal; accepts DC-coupled or AC-coupled signals across full common-mode range. |
| 4 | N.C. | No internal connection; must be left floating or tied to ground per layout best practices to minimize parasitic coupling. |
| 5 | VCC | Positive supply rail (3.3V–10V); requires local 0.1µF ceramic bypass capacitor placed adjacent to pin for stable high-frequency operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers 4.9VP-P swing on 5V supply with <60mV headroom to each rail - maximizes dynamic range in single-supply data converters and video DAC buffers. |
| Unity-gain stable design | Internally compensated for stable operation at AV = 1 without external compensation - simplifies design of video line drivers and unity-gain followers. |
| Low differential gain/phase error | 0.02%/0.02° at NTSC frequencies - eliminates visible color smearing and hue shifts in broadcast-quality video routing and switching systems. |
| High output drive capability | ±120mA sourcing/sinking - directly drives 50Ω or 75Ω coaxial cables, back-terminated transmission lines, and multiple parallel loads without external buffers. |
| Ground-sensing input stage | Accepts inputs down to VEE − 0.2V - enables direct interfacing with ground-referenced sensors, ADC outputs, and legacy analog circuitry in 3.3V/5V systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4200EUK-T | Same SOT23-5 package; 220MHz bandwidth, 800V/µs slew rate, but higher 7.5mA supply current and no guaranteed 0.02% differential gain spec. | Better speed for RF IF stages; less validated for broadcast video due to missing differential gain/phase characterization. | Select when >200MHz small-signal bandwidth is required and video fidelity specs are secondary to raw speed. |
| LMH6629MA/NOPB | SO-8 package; 1.5GHz bandwidth, 1100V/µs slew rate, 12mA supply current; rail-to-rail input only (not output); higher cost and larger footprint. | Targeted at RF/IF and high-end test equipment; unsuitable for space-constrained video line drivers due to SO-8 size and non-rail-to-rail output. | Select for GHz-range signal chains where output swing headroom is less critical than bandwidth and noise floor. |
Compared with MAX4200EUK-T and LMH6629MA/NOPB, the MAX4012EUK offers the optimal balance of video-grade linearity (0.02%/0.02°), compact SOT23-5 packaging, and 5.5mA power efficiency - making it the preferred choice for cost-sensitive, space-constrained, broadcast-compliant video routing and portable instrumentation.

FAQ
What is the maximum operating supply voltage for the MAX4012EUK?
The MAX4012EUK supports a supply voltage range of 3.3V to 10V for single-supply operation, or ±1.65V to ±5V for dual-supply use. Absolute maximum rating is 12V between VCC and VEE. Exceeding this risks permanent damage. Operation at 10V is fully characterized and supported across the −40°C to +85°C temperature range, with no derating required.
Does the MAX4012EUK have an enable/disable function?
No, the MAX4012EUK does not include an enable/disable feature. That functionality is exclusive to the MAX4018 and MAX4020 variants in the same family. The MAX4012EUK is a permanently active single op amp with no EN pin; its quiescent current remains fixed at 5.5mA (typical) under all operating conditions.
Can the MAX4012EUK drive a 50Ω load directly?
Yes, the MAX4012EUK can drive a 50Ω load directly with full rail-to-rail output swing and minimal distortion. Its ±120mA output current capability and low 6Ω closed-loop output impedance (at 10MHz) ensure stable 2VP-P signal delivery into 50Ω, as validated in the typical operating circuit using RF = 24Ω and RO = RTO = 50Ω.
What is the input offset voltage specification for the MAX4012EUK?
The MAX4012EUK has a guaranteed maximum input offset voltage of 4mV over the full −40°C to +85°C temperature range, with a typical value of 2mV at +25°C. Its input offset voltage temperature coefficient is 8µV/°C, ensuring predictable drift behavior in thermally varying environments such as portable test gear and outdoor surveillance enclosures.
Is the MAX4012EUK unity-gain stable?
Yes, the MAX4012EUK is internally compensated for unity-gain stability. It requires no external compensation components when configured as a unity-gain follower or inverting amplifier. The datasheet specifies stable operation with RF = 24Ω in unity-gain configuration, and small-signal gain flatness remains within ±0.1dB up to 30MHz under those conditions.
