AD9648TCPZ125EPRL7

Analog To Digital Converters (ADC) Overview

The AD9648TCPZ125EPRL7 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Analog Devices Inc. It operates at sampling rates up to 125 MSPS with a single 1.8 V analog supply and supports 1.8 V CMOS or LVDS digital outputs. The device features a differential analog input with a 650 MHz bandwidth and an on-chip voltage reference. Key performance metrics include a signal-to-noise ratio of 74.5 dBFS at 70 MHz and a spurious-free dynamic range of 91 dBc at 70 MHz. Power consumption is 106 mW per channel at maximum speed. It utilizes a multistage differential pipeline architecture with output error correction logic.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the component matches the Enhanced Product (EP) designation to ensure compliance with the specified military temperature range and AQEC standards. Confirm the package type corresponds to the 64-lead LFCSP variant. Check qualification data availability if required for specific aerospace or defense procurement protocols.

Analog To Digital Converters (ADC) Selection Notes

Select this model when system requirements demand operation in extreme temperatures between −55°C and +125°C. Ensure the design accommodates the 64-lead LFCSP footprint. Verify compatibility with 1.8 V CMOS or LVDS logic families for the digital interface. Consider the pin-compatible migration path to other ADI ADCs if future resolution changes are anticipated.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9648-EP family, which is the enhanced product version of the standard AD9648. It shares the same functional specifications but is distinguished by its extended temperature rating and controlled manufacturing baseline. It is designed for high-reliability environments where standard commercial grade components are insufficient.

Analog To Digital Converters (ADC) Replacement Considerations
