MAX4202ESA+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4202ESA+ is a single-channel, ultra-high-speed open-loop buffer manufactured by Analog Devices Inc./Maxim Integrated. It features integrated 75Ω back-termination resistors designed for driving 75Ω transmission lines. The device operates from ±4V to ±5.5V supplies with a quiescent current of 2.2mA per buffer. Key electrical parameters include a 780MHz -3dB bandwidth, 280MHz 0.1dB gain flatness, and a 4200V/μs slew rate. It provides ±90mA output drive capability and exhibits low noise characteristics with 2.1nV/√Hz voltage-noise density and 0.8pA/√Hz current-noise density.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package configuration against the datasheet selector guide, as the MAX4202 series is available in both SOIC and SOT23 packages. Confirm that the ordering suffix corresponds to the desired packaging format. Ensure compatibility with dual supply voltages ranging from ±4V to ±5.5V during system design validation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the MAX4202ESA+ when driving 75Ω coaxial cables or transmission lines due to its internal 75Ω termination. Choose this model over the MAX4200 or MAX4201 if impedance matching for 75Ω systems is required. Consider the dual-supply operation requirements and verify that the high slew rate meets the signal integrity needs of the target application.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX4202ESA+ belongs to the MAX4200–MAX4205 family of ultra-high-speed, low-noise, low-power open-loop buffers. This family includes single and dual channel variants with varying internal termination options. The MAX4202 specifically addresses applications requiring 75Ω output termination, distinguishing it from the un-terminated MAX4200 and the 50Ω terminated MAX4201.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include the MAX4205, which offers identical functionality but in a dual-channel configuration.
