MAX7449EUD

Overview

The MAX7449EUD is a high-speed, low-power, single-supply operational amplifier manufactured by Analog Devices Inc. (Maxim Integrated). It features a wide bandwidth and fast slew rate suitable for demanding signal processing applications. The device operates on a single supply voltage ranging from 2.7V to 12V. It is housed in an 8-MSOP package with exposed pad. Key electrical characteristics include a gain-bandwidth product of 35MHz and a slew rate of 20V/µs. The input common-mode voltage range extends to the negative rail, while the output swings within 50mV of the rails. Quiescent current per channel is typically 6mA.

Feature Summary

• Single-supply operation capability
• Rail-to-rail input and output performance
• High slew rate for fast transient response

Applications

• Video buffering and driving
• Portable instrumentation
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'EUD' against the manufacturer's official datasheet to confirm the package type and temperature grade. Ensure compatibility with existing PCB footprints for the 8-MSOP configuration. Check for RoHS compliance status as indicated in the latest component documentation before finalizing procurement.

Selection Notes

Select this component when a single-supply op-amp with rail-to-rail I/O is required in a compact surface-mount package. Consider the 35MHz bandwidth and 20V/µs slew rate for video or high-speed data applications. Compare power consumption requirements against other members of the MAX49x family if lower quiescent current is needed.

Part Context

The MAX7449 belongs to the MAX49x series of high-speed, low-power operational amplifiers. This family is designed for applications requiring good AC performance with minimal power dissipation. The EUD variant specifically denotes the MSOP package option within this product line.

Replacement Considerations

Direct pin-compatible replacements within the same family may include other variants of the MAX49x series. Verify electrical specifications such as bandwidth and slew rate match the original design requirements before substituting.
