Product details
Overview
MAX4212EUK from Maxim Integrated is a single, unity-gain-stable, rail-to-rail output operational amplifier in a 5-pin SOT23 package, delivering 300MHz -3dB bandwidth, 600V/µs slew rate, and 10nV/√Hz input voltage noise. It operates from a single 3.3V–10V supply or dual ±1.65V–±5V supplies and is optimized for video line driving, ADC interface, and battery-powered instrumentation.
For engineers reviewing the MAX4212EUK datasheet, MAX4212EUK pinout, MAX4212EUK application, or MAX4212EUK equivalent, key selection criteria include its rail-to-rail output swing (within 50mV of rails), low 5.5mA quiescent current, high-output drive (±100mA), differential gain/phase accuracy (0.02%/0.02°), and compatibility with 50Ω video routing systems.
Technical Context
The MAX4212EUK employs a voltage-feedback architecture enhanced with current-feedback techniques to achieve high-speed performance while maintaining unity-gain stability. 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 systems.
It features internally compensated unity-gain configuration requiring only a 24Ω feedback resistor (RF) for optimal AC response. The device lacks an enable/disable function-unlike the MAX4213/MAX4218-so it operates continuously without shutdown control or high-impedance output state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 300MHz - enables full NTSC/PAL video bandwidth and high-fidelity signal amplification up to 100MHz fundamental frequencies. |
| Slew Rate | 600V/µs - supports fast transient response for 2VP-P signals at 5MHz without distortion. |
| Input Voltage Noise | 10nV/√Hz - preserves SNR in low-level analog front-ends such as CCD imaging and precision ADC drivers. |
| Output Drive | ±100mA - drives 50Ω transmission lines directly or sustains 150Ω loads with minimal droop in video routing applications. |
| Supply Range | 3.3V to 10V single supply - compatible with Li-ion battery systems (3.3V–4.2V), 5V logic rails, and industrial 9V supplies. |
| Output Swing | Within 50mV of each rail (RL = 10kΩ) - maximizes dynamic range in 5V systems (4.9VPP output for 2.95VPP input). |
| Differential Gain/Phase | 0.02% / 0.02° - meets broadcast-grade video fidelity requirements for NTSC and PAL composite video. |
Pinout & Package
MAX4212EUK is housed in a 5-pin SOT23-5 package (JEDEC MO-178AA), measuring 2.9mm × 1.6mm × 1.1mm, with gull-wing leads and RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Amplifier output | Delivers rail-to-rail voltage swing; requires no external pull-up/down; connects directly to 50Ω load or coaxial cable. |
| 2 - IN− | Inverting input | High-impedance node (70kΩ typical); used for feedback in inverting configurations or gain-setting networks. |
| 3 - IN+ | Noninverting input | Supports common-mode input down to VEE − 0.2V; enables ground-referenced sensor interfaces in single-supply systems. |
| 4 - VEE | Negative supply / ground | Reference for single-supply operation (0V); must be bypassed with 0.1µF capacitor near pin for stability. |
| 5 - VCC | Positive supply | Accepts 3.3V–10V; requires local 0.1µF ceramic decoupling to suppress high-frequency supply noise. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 50mV of VCC and VEE under 10kΩ load - preserves >98% of available voltage headroom in 5V systems. |
| Unity-gain stable | Internally compensated for AVCL = +1; requires only 24Ω series feedback resistor - eliminates external compensation components. |
| Low input noise | 10nV/√Hz voltage noise + 1.3pA/√Hz current noise - maintains signal integrity in high-gain, wideband stages before ADCs or RF mixers. |
| High output drive | ±100mA short-circuit current - drives back-terminated 50Ω video lines without external buffers or level-shifting circuitry. |
| Ground-sensing input | Common-mode range extends to VEE − 0.2V - allows direct connection of 0V-referenced sensors (e.g., thermocouples, photodiodes) in single-supply designs. |
Applications
| Video Line Driver | Analog-to-Digital Converter Interface |

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 |
|---|---|---|---|
| LMH6629MA/NOPB | Higher 1.5GHz GBW but higher 12.5mA supply current; no rail-to-rail output (clips ~1.2V from rails); 8-pin SOIC only. | Not suitable for rail-to-rail output swing or low-power battery operation; better for DC-coupled IF amplification where headroom is less critical. | Select when ultra-wide bandwidth (>1GHz) outweighs power and output swing constraints. |
| ADA4817-1ARMZ | 1GHz GBW, 1.1nV/√Hz noise, but requires dual supply or negative rail; 6-pin SOT23 package; no internal unity-gain compensation. | Requires external compensation and negative supply generation - increases BOM count and layout complexity vs. MAX4212EUK's single-supply simplicity. | Choose for ultra-low-noise, high-precision applications where dual supply is available and external compensation is acceptable. |
Compared with LMH6629MA/NOPB and ADA4817-1ARMZ, the MAX4212EUK uniquely combines rail-to-rail output, unity-gain stability, 5.5mA quiescent current, and SOT23-5 packaging - making it the only option among the three that delivers broadcast-grade video fidelity in space-constrained, single-supply portable instruments.

FAQ
What is the maximum operating supply voltage for the MAX4212EUK?
The MAX4212EUK supports a maximum supply voltage of 12V across VCC to VEE, with absolute maximum ratings specifying 12V differential. Its recommended operating range is 3.3V to 10V for single-supply use, and ±1.65V to ±5V for dual-supply configurations. Operation beyond 10V single supply or ±5V dual supply risks exceeding thermal limits and degrading long-term reliability, even if within absolute max ratings.
Does the MAX4212EUK have an enable/disable pin?
No, the MAX4212EUK does not include an enable/disable function. Unlike the MAX4213 or MAX4218 variants, it lacks an EN pin and operates continuously whenever powered. Its quiescent supply current remains fixed at 5.5mA (typical) with no shutdown mode or high-impedance output state. This simplifies design for always-on applications but precludes power-gating strategies.
What is the typical output voltage swing of the MAX4212EUK with a 5V supply?
With a 5V single supply (VCC = 5V, VEE = 0V), the MAX4212EUK delivers a typical output voltage swing of 4.9VPP into a 10kΩ load - meaning it swings from within 50mV of VEE (0.05V) to within 50mV of VCC (4.95V). This rail-to-rail capability maximizes dynamic range and is confirmed in the datasheet's "Output Voltage Swing" table under RL = 10kΩ conditions.
Can the MAX4212EUK drive a 50Ω load directly?
Yes, the MAX4212EUK can drive a 50Ω load directly, delivering ±100mA output current. In unity-gain configuration with a 24Ω feedback resistor (as specified in the datasheet), it maintains stability and achieves <0.02% differential gain error into 50Ω. However, output swing reduces to ~3.8VPP under 50Ω load due to I×R drop - verified in the "Output Voltage Swing" table for RL = 50Ω.
What is the input common-mode voltage range of the MAX4212EUK?
The MAX4212EUK supports an input common-mode voltage range from (VEE − 0.2V) to (VCC − 2.25V). With a 5V single supply (VEE = 0V), this translates to −0.2V to +2.75V - enabling true ground-sensing operation and compatibility with 0V-referenced sensors. This range is explicitly guaranteed in the "DC Electrical Characteristics" table under the VCM parameter.
