Product details
Overview
MAX4202EUK+T from Maxim Integrated is a single-channel, ultra-high-speed open-loop buffer optimized for 75Ω coaxial cable driving applications. It delivers 780MHz -3dB bandwidth, 280MHz 0.1dB gain flatness, 4200V/μs slew rate, ±44mA output current, and integrated 75Ω back-termination resistor - enabling direct interface with video and IF signal distribution systems.
For engineers reviewing the MAX4202EUK+T datasheet, MAX4202EUK+T pinout, MAX4202EUK+T application, or MAX4202EUK+T equivalent, this page provides verified electrical parameters, SOT23-5 package layout guidance, real-world capacitive-load stability behavior, and validated alternatives for 75Ω transmission-line driver replacement.
Technical Context
The MAX4202EUK+T employs a proprietary open-loop architecture eliminating dominant-pole compensation, achieving near-constant 405ps group delay across its full bandwidth. Its internal 75Ω termination resistor forms a precise voltage divider with the 75Ω load, delivering predictable gain of 0.41–0.59 V/V while suppressing reflections on high-frequency analog video and IF lines.
Unlike closed-loop amplifiers, it avoids instability with capacitive loads due to absence of phase-shifted feedback; instead, performance degrades predictably via RC roll-off (RT = 75Ω + CL), with peaking mitigated by inherent output impedance characteristics and optional external isolation resistors.
Key Specifications

|---|---|
| -3dB Bandwidth | 780MHz - supports full NTSC/PAL video baseband and multi-carrier IF signals up to UHF without attenuation |
| 0.1dB Gain Flatness | 280MHz - ensures amplitude fidelity across wideband communication channels including WLAN and cable TV upstream bands |
| Slew Rate | 4200V/μs - enables clean 2VP-P pulse response with ≤12ns settling to 0.1%, critical for high-resolution ADC/DAC clock feedthrough suppression |
| Output Drive | ±44mA into 75Ω - sustains 2.0–2.3VP-P swing at full load, sufficient for broadcast-quality SD/HD video line driving |
| Voltage-Noise Density | 2.1nV/√Hz at 1MHz - preserves SNR in low-level IF amplification stages where noise floor directly impacts receiver sensitivity |
| Supply Current | 2.2mA per buffer - enables dual-rail ±5V operation with minimal thermal impact in dense RF front-end layouts |
| Operating Temp | -40°C to +85°C - qualified for industrial video infrastructure and outdoor wireless access point environments |
Pinout & Package
MAX4202EUK+T is housed in a 5-pin SOT23-5 package (package code U5-1), with exposed pad not internally connected. The compact 2.9mm × 1.6mm footprint supports high-density RF board layouts while maintaining thermal performance up to 70°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - N.C. | No Connection | Not internally bonded; must be left floating or grounded per PCB EMI control requirements |
| 2 - VEE | Negative Power Supply | Accepts -4V to -5.5V; requires local 0.1μF ceramic bypass to ground plane for high-frequency PSR stability |
| 3 - IN | Buffer Input | 500kΩ || 2pF input impedance; requires 75Ω source termination to prevent peaking above 100MHz |
| 4 - OUT | Buffer Output | 75Ω series termination integrated; delivers matched drive to 75Ω coax without external resistor |
| 5 - VCC | Positive Power Supply | Accepts +4V to +5.5V; shares same bypassing requirement as VEE for symmetrical rail rejection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 75Ω transmission-line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4202ESA+ | Same electrical specs, but in 8-pin SO package (S8-2); no integrated thermal pad; larger footprint (4.9mm × 6.0mm) | Better heat dissipation at sustained ±44mA loads; suited for through-hole prototyping or legacy SO-based designs | Select when board space permits larger package and thermal management prioritizes convection over conduction |
| THS3201DGN | Higher 1.8GHz bandwidth, but no integrated 75Ω termination; requires external 75Ω series resistor; 2.5mA supply current | Supports wider IF bands (e.g., 5G NR sub-6GHz), but adds layout complexity and parasitic inductance risk at >500MHz | Select when system bandwidth exceeds 780MHz and board-level termination control is acceptable |
Compared with MAX4202EUK+T, MAX4202ESA+ offers identical performance in a larger SO package ideal for thermal-heavy applications, while THS3201DGN trades integrated termination for higher bandwidth - requiring careful layout to match MAX4202EUK+T's 75Ω drive integrity above 200MHz.

FAQ
What is the exact function of the integrated 75Ω resistor in MAX4202EUK+T?
The integrated 75Ω resistor in MAX4202EUK+T is a series output termination placed between the internal amplifier core and the OUT pin. It forms a matched voltage divider with the 75Ω load, ensuring reflection-free signal transmission on coaxial cables. This eliminates the need for an external resistor, reduces parasitic inductance, and maintains return loss better than 20dB up to 500MHz - a key advantage confirmed in the MAX4202EUK+T datasheet Figure 5 and Typical Application Circuit.
Can MAX4202EUK+T drive capacitive loads without oscillation?
Yes, MAX4202EUK+T remains stable with capacitive loads up to at least 120pF without oscillation, as demonstrated in Figure 5 of the MAX4202EUK+T datasheet. Its open-loop architecture avoids phase-shifted feedback loops that cause instability in closed-loop amplifiers. However, bandwidth rolls off predictably (RC-limited by 75Ω + CL), and peaking may occur - which the integrated 75Ω termination helps dampen compared to non-terminated variants like MAX4200EUK+T.
What is the guaranteed gain accuracy of MAX4202EUK+T into a 75Ω load?
The MAX4202EUK+T guarantees a voltage gain of 0.41V/V (min) to 0.59V/V (max) into a 75Ω load, per the DC Electrical Characteristics table. This corresponds to a nominal -6dB attenuation due to the internal 75Ω series resistor forming a 2:1 voltage divider with the load. Gain flatness is maintained within ±0.1dB up to 280MHz, making MAX4202EUK+T suitable for amplitude-critical IF and video applications where passband ripple must be minimized.
Does MAX4202EUK+T require external compensation components?
No, MAX4202EUK+T does not require external compensation components. Its proprietary open-loop architecture omits dominant-pole compensation, enabling intrinsic stability across its full bandwidth. The device is characterized for stable operation with no external feedback network - unlike voltage-feedback op-amps. Layout best practices (e.g., short traces, local 0.1μF bypassing at VCC/VEE) are sufficient; no compensation capacitors or resistors are specified or needed for basic 75Ω driving applications.
How does MAX4202EUK+T compare to MAX4201EUK+T in terms of system-level performance?
MAX4202EUK+T and MAX4201EUK+T share identical bandwidth (780MHz), slew rate (4200V/μs), and noise (2.1nV/√Hz), but differ in termination: MAX4202EUK+T uses 75Ω for video/IF systems, while MAX4201EUK+T uses 50Ω for RF/data comms. Their gain into matched loads differs (0.41–0.59V/V vs. 0.42–0.58V/V), and output drive is ±44mA vs. ±52mA. Thus, MAX4202EUK+T is optimized for broadcast video standards, whereas MAX4201EUK+T targets 50Ω instrumentation and telecom interfaces.
