MAX4228ESD

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4228ESD is a single-channel, current-feedback amplifier from the MAX4223–MAX4228 family, optimized for closed-loop gains of +2 (6dB) or higher. It features a -3dB bandwidth of 600MHz and a gain-bandwidth product of 1.2GHz. The device operates on dual supplies ranging from ±2.85V to ±5.5V with a typical quiescent supply current of 6.0mA per amplifier. It includes a shutdown feature that reduces power consumption to 350µA and places outputs in a high-impedance state. Available in an 8-pin SO package, it supports an operating temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'ESD' against official Analog Devices documentation to confirm package type and temperature range. Ensure compatibility with the required closed-loop gain configuration (+2 or greater) as this variant is compensated for gains of +2 (6dB) or more. Confirm pinout alignment with the 8-pin SO package specification before integration into the design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the MAX4228ESD when a closed-loop gain of +2 (6dB) or higher is required, as it offers superior AC performance compared to unity-gain optimized variants at these settings. Consider the shutdown feature if power management or multiplexing capabilities are necessary. Evaluate the 8-pin SO package constraints against board space requirements and thermal dissipation needs for the target application environment.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the MAX4223–MAX4228 series of ultra-high-speed, low-power current-feedback amplifiers. The series combines high-speed performance with low distortion and excellent video specifications. While some models in the family are optimized for unity gain, the MAX4228 specifically targets applications requiring gains of +2 or more, providing a balanced solution for professional video and data communications systems.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include the MAX4227ESA, which shares identical electrical characteristics and compensation for gains of +2 or greater. Both devices offer the same 600MHz bandwidth and shutdown functionality. Verify package compatibility between the SO-8 and any alternative packages before substitution.
