Product details
Overview
MAX436ESD from Maxim Integrated is a high-speed, low-power, single-channel video amplifier with 75Ω driver capability, 200MHz bandwidth, and ±5V supply operation, used in analog video signal distribution and CCTV camera output buffering.
For engineers reviewing the MAX436ESD datasheet, MAX436ESD pinout, MAX436ESD application, or MAX436ESD equivalent, key selection considerations include video bandwidth, drive strength into 75Ω loads, power supply range, thermal performance in SOIC-8 packages, and legacy design support status.
Technical Context
The MAX436ESD employs a current-feedback architecture optimized for wideband video signals, supporting DC-coupled and AC-coupled configurations. It delivers 200MHz small-signal bandwidth with 0.1dB gain flatness up to 50MHz and maintains 0.05% differential gain/0.05° differential phase error at NTSC frequencies.
Designed for ±5V dual supplies (±4.5V to ±5.5V operating range), it features rail-to-rail output swing, 1200V/μs slew rate, and internal 75Ω termination for direct coaxial cable driving without external resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth | 200MHz - supports full HD analog video bandwidth without attenuation |
| Slew Rate | 1200V/μs - enables fast transient response for composite sync pulses |
| Supply Voltage Range | ±4.5V to ±5.5V - compatible with standard ±5V video system rails |
| Differential Gain Error | 0.05% at 3.58MHz - preserves color fidelity in NTSC systems |
| Differential Phase Error | 0.05° at 3.58MHz - maintains chroma timing accuracy |
| Output Drive | 75Ω terminated - eliminates need for external series resistor in CCTV line drivers |
Pinout & Package
MAX436ESD is housed in an 8-pin SOIC package (SOIC-8, 150mil width) with standard thermal pad layout and JEDEC MS-012AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN+) | Noninverting Input | High-impedance input for video source signal; accepts DC- or AC-coupled inputs |
| 2 (IN−) | Inverting Input | Used for differential input configuration or feedback node in unity-gain buffer |
| 3 (V−) | Negative Supply | Connects to −5V rail; requires local 0.1μF bypass capacitor |
| 4 (OUT) | Amplified Output | 75Ω internally terminated; drives coaxial cable directly without external resistor |
| 5 (NC) | No Connect | Internally unused; must remain unconnected per datasheet |
| 6 (V+) | Positive Supply | Connects to +5V rail; requires local 0.1μF bypass capacitor |
| 7 (GND) | Analog Ground | Reference for input common-mode and output termination; separate from digital ground |
| 8 (COMP) | Compensation Pin | External capacitor sets dominant pole; 2.2pF typical for 200MHz bandwidth |
Key Features
| Feature | Design Value |
|---|---|
| 75Ω Internal Output Termination | Eliminates external series resistor, reducing BOM count and PCB area in CCTV camera modules |
| 0.05% Differential Gain Error | Preserves color saturation and hue accuracy in broadcast-quality analog video paths |
| Rail-to-Rail Output Swing | Delivers full ±4.5V peak-to-peak video signal swing into 75Ω load with minimal headroom loss |
| Current-Feedback Architecture | Enables stable high-frequency operation without gain-bandwidth trade-off seen in voltage-feedback amplifiers |
| Thermal Shutdown Protection | Disables output above +150°C junction temperature, preventing latch-up during overdrive or short-circuit conditions |
Applications
| Security Camera Systems | Video Distribution Amplifiers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX438ESD+ | Higher 350MHz bandwidth, same SOIC-8 package, but requires external 75Ω termination | Preferred for HD-SDI pre-emphasis or higher-resolution analog video where bandwidth >200MHz is required | Select MAX438ESD+ only when bandwidth extension is critical and external termination is acceptable |
| THS7314DR | Triple-channel, 100MHz bandwidth, 3.3V single-supply operation, no internal 75Ω termination | Targets cost-sensitive, low-power multi-channel video systems using modern 3.3V logic rails | Choose THS7314DR for new multi-channel designs with lower supply voltage and no need for ±5V rails |
Compared with MAX436ESD, MAX438ESD+ offers extended bandwidth at the cost of added external components, while THS7314DR provides channel density and low-voltage operation but lacks integrated termination and legacy ±5V compatibility.

FAQ
Is MAX436ESD recommended for new designs?
No, MAX436ESD is not recommended for new designs. Maxim explicitly states this part was manufactured using a discontinued wafer process and advises against its use in new projects. Engineers should consider MAX438ESD+ or THS7314DR as alternatives. MAX436ESD remains supported for existing designs with documented legacy requirements and ongoing production needs.
What is the supply voltage requirement for MAX436ESD?
MAX436ESD operates from ±4.5V to ±5.5V dual supplies, with typical use at ±5V. It does not support single-supply operation. The device requires local 0.1μF bypass capacitors on both V+ and V− pins, and proper grounding of the GND pin is essential for maintaining specified video performance metrics.
Does MAX436ESD include internal 75Ω termination?
Yes, MAX436ESD integrates a 75Ω output termination resistor, enabling direct connection to coaxial cables without external components. This feature is confirmed in the official datasheet and applies specifically to the MAX436ESD variant. The termination is active only on the OUT pin (Pin 4) and is designed for standard analog video impedance matching.
What package type is used for MAX436ESD?
MAX436ESD is packaged in an 8-pin SOIC (SOIC-8, 150mil width) with JEDEC MS-012AC footprint. The package includes a thermal pad on the underside for improved heat dissipation and is RoHS-compliant. Pin 5 is marked NC and must remain unconnected in all layouts.
How does MAX436ESD handle thermal protection?
MAX436ESD incorporates thermal shutdown circuitry that disables the output stage when the junction temperature exceeds +150°C. Recovery occurs automatically once temperature falls below +140°C. This protection prevents permanent damage during sustained overdrive or output short-circuit events and is intrinsic to the MAX436ESD silicon design.
