Product details
Overview
MAX4350EXK from Maxim Integrated is a single, unity-gain-stable, rail-to-rail output voltage-feedback op amp optimized for high-speed video and instrumentation signal conditioning. It operates from dual ±5V supplies, delivers 210MHz -3dB bandwidth, 485V/µs slew rate, and achieves 0.02% differential gain / 0.08° differential phase error into 150Ω - making it ideal for NTSC video line driving and ADC interface circuits.
For engineers reviewing the MAX4350EXK datasheet, MAX4350EXK pinout, MAX4350EXK application, or MAX4350EXK equivalent, key selection criteria include its SC70-5 package footprint, rail-to-rail output swing within 125mV of rails, input common-mode range extending to VEE, low 6.9mA quiescent current per amplifier, and verified performance in 75Ω/150Ω video termination topologies.
Technical Context
The MAX4350EXK employs a hybrid voltage-feedback architecture with current-feedback techniques to achieve wide bandwidth and fast settling (16ns to 0.1%). Its input stage supports common-mode voltages from VEE to (VCC – 2.25V), and its output stage uses local feedback to maintain low open-loop output impedance (8Ω typical) across frequency.
Internally compensated for unity-gain stability, the device requires only a 24Ω series feedback resistor (RF) in unity-gain configuration to optimize AC response and suppress parasitic LC resonance. It is not designed for direct capacitive loads >10pF without isolation resistance, and exhibits stable operation only with proper high-frequency layout - including microstrip routing, 0.1µF supply bypassing, and avoidance of sockets or wire-wrap.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 210MHz at 100mVP-P - enables full HD video signal amplification without attenuation in baseband. |
| Slew Rate | 485V/µs - supports clean 2V step response with <16ns settling to 0.1%, critical for pulse fidelity in digital video interfaces. |
| Output Swing | Rails ±125mV into 2kΩ - delivers near-full dynamic range in ±5V systems, minimizing headroom loss in analog signal chains. |
| Differential Gain/Phase | 0.02%/0.08° @ NTSC, RL = 150Ω - meets broadcast-grade video specification for color fidelity in set-top boxes and surveillance systems. |
| Supply Current | 6.9mA per amplifier - enables integration into power-constrained portable or multi-channel video front-ends without thermal penalty. |
| Input Common-Mode Range | VEE to (VCC – 2.25V) - allows ground-sensing operation in single-supply-derived bias networks and DC-coupled sensor interfaces. |

Pinout & Package
The MAX4350EXK is housed in a 5-pin SC70 package (3.0mm × 1.75mm × 0.9mm body height), optimized for space-constrained video routing PCBs and portable imaging modules.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN– | Inverting input terminal; accepts differential or single-ended signals with common-mode range down to VEE. |
| 2 | IN+ | Noninverting input terminal; used for unity-gain buffer or noninverting gain configurations with RF/RG network. |
| 3 | OUT | Amplifier output; rail-to-rail capable, specified for ≤125mV saturation margin into 2kΩ load. |
| 4 | VEE | Negative supply pin; must be bypassed with 0.1µF capacitor to ground for high-frequency stability. |
| 5 | VCC | Positive supply pin; requires independent 0.1µF bypass to ground; supports ±4.5V to ±5.5V dual-supply operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Swings within 125mV of VCC and VEE into 2kΩ, preserving signal amplitude integrity in ±5V video driver stages. |

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 |
|---|---|---|---|
| THS3201DR | Higher 1.8GHz GBW but requires ±15V supplies; no rail-to-rail output; 12mA IQ. | Better for wideband RF IF amplification, unsuitable for ±5V video line driving due to output swing limitation. | Select when >500MHz small-signal bandwidth is required and supply headroom permits ±15V operation. |
| ADA4817-1ARMZ | 1GHz GBW, 250V/µs slew, rail-to-rail output, but 12.5mA IQ and SO-8 package; lower differential gain accuracy (0.05%). | Acceptable for general-purpose high-speed buffering where video color fidelity is secondary to bandwidth. | Prefer when board space allows SO-8 and system prioritizes raw speed over NTSC-specific distortion metrics. |
Compared with THS3201DR and ADA4817-1ARMZ, the MAX4350EXK uniquely balances 210MHz bandwidth, ±5V dual-supply compatibility, rail-to-rail output, and broadcast-grade video linearity in an ultra-compact SC70-5 package - making it the optimal choice for cost- and size-sensitive video signal chain designs.

FAQ
What supply voltages does the MAX4350EXK support?
The MAX4350EXK operates from dual ±4.5V to ±5.5V supplies, with typical use at ±5V. It is not rated for single-supply operation; VEE must be actively driven (e.g., –5V), not tied to ground. Operation outside this range risks parametric shift or damage, as absolute maximum ratings cap total supply voltage at +12V (VCC – VEE).
Does the MAX4350EXK require external compensation for unity-gain stability?
No - the MAX4350EXK is internally compensated for unity-gain stability. However, a 24Ω resistor (RF) must be placed in series with the feedback path to optimize AC performance and suppress peaking caused by parasitic capacitance. Omitting RF degrades gain flatness and may induce oscillation above 50MHz.
Can the MAX4350EXK drive 75Ω coaxial cable directly?
Yes - the MAX4350EXK is characterized for 75Ω source termination (RO = 75Ω, RTO = 75Ω, RF = 24Ω) in unity-gain line driver configurations. Its low 8Ω open-loop output impedance and 485V/µs slew rate ensure minimal rise-time degradation and reflection control when properly terminated at both ends.
What is the input common-mode voltage range of the MAX4350EXK?
The MAX4350EXK supports an input common-mode range from VEE to (VCC – 2.25V). At ±5V supplies, this spans –5V to +2.75V - enabling ground-referenced inputs and compatibility with DC-coupled video sources or sensor outputs without level-shifting circuitry.
Is the MAX4350EXK pin-compatible with other SC70-5 op amps?
No - the MAX4350EXK has a proprietary SC70-5 pinout (IN–, IN+, OUT, VEE, VCC) that differs from industry-standard SC70 op amps like the MAX4475 or OPA355. Direct replacement requires PCB layout revision; functional alternatives must be evaluated for both electrical behavior and physical pin mapping.
