MAX2557AELM+

Video Amps And Modules Overview

The MAX2557AELM+ is a high-speed, low-power dual analog-to-digital converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It features fully differential wideband track-and-hold inputs optimized for intermediate frequency and baseband sampling applications. The device operates from a single 3.3V supply, consuming approximately 610mW to 637mW depending on clock mode. It delivers high dynamic performance with a typical signal-to-noise ratio of 72.5dB at 175MHz input frequency. The ADC accepts single-ended or differential inputs up to 400MHz and includes user-selectable clock modes and power-down functionality.

Video Amps And Modules Procurement Notes

Verify the specific suffix 'AELM+' against official datasheets to confirm package type and temperature grade. Confirm availability status as this component may be subject to limited supply or obsolescence notices. Ensure compatibility with required clock duty cycles and reference configurations before procurement.

Video Amps And Modules Selection Notes

Select this component for applications requiring high-speed conversion with low power consumption. Consider the 68-pin Thin QFN package for size constraints. Evaluate the need for differential versus single-ended clock inputs and verify that the 3.3V supply aligns with system power architecture. Check if the 12-bit compatible version is sufficient for lower resolution requirements.

Video Amps And Modules Part Context

This part belongs to the MAX12557 family of dual ADCs designed for high-performance RF and baseband processing. It shares architectural similarities with other Maxim Integrated high-speed converters but is distinct in its specific pinout and power characteristics. The device is engineered to replace older discrete solutions in communication receiver front-ends.

Video Amps And Modules Replacement Considerations

The MAX12527 is a documented 12-bit compatible version within the same family. Verify pin compatibility and performance trade-offs when considering substitutes. No other direct cross-references are confirmed in public documentation.
