MAX4226EUB+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4226EUB+ is a single-channel, ultra-high-speed current-feedback amplifier from the Analog Devices/MAXIM MAX4223–MAX4228 family. It operates on dual supplies ranging from ±2.85V to ±5.5V with a typical quiescent supply current of 6.0mA per amplifier. Optimized for closed-loop gains of +1 (0dB) or more, it provides a -3dB bandwidth of 1GHz and a slew rate of 1100V/µs. The device features a low-power shutdown mode that reduces supply current to 350µA and places outputs in a high-impedance state. It is housed in a 10-pin µMAX package and supports an operating temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix matches the required package type, as the MAX4226 series includes various pin configurations such as SOT23, SO, and µMAX. Confirm that the selected variant includes the shutdown feature, which is not present in all members of the MAX422x family. Ensure compatibility with dual power supply requirements and check for any specific thermal derating needs associated with the chosen package style during procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the MAX4226EUB+ when designing circuits requiring a 1GHz bandwidth at a closed-loop gain of +1 or higher. This component is suitable for applications demanding low distortion and fast settling times. Consider the shutdown functionality if power management or multiplexing capabilities are required. Verify that the system can accommodate dual polarity power supplies within the specified voltage range for optimal performance.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX4226EUB+ belongs to the MAX4223–MAX4228 series of current-feedback amplifiers designed for professional video and data communications. These devices combine high speed with low power consumption. Unlike voltage-feedback amplifiers, these use a current-mode topology allowing for consistent bandwidth regardless of gain settings above the minimum threshold. The EUB+ designation indicates a specific surface-mount package configuration within this high-performance analog signal processing family.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct replacements within the same family include the MAX4223, MAX4225, and MAX4228, provided they share the identical package footprint and pinout. Note that the MAX4223/MAX4224/MAX4228 also feature shutdown modes, whereas the MAX4225 does not. Ensure that any substitute maintains the 1GHz bandwidth specification required for the application.
