AD9260ASRL

Analog To Digital Converters (ADC) Overview

The AD9260ASRL is a monolithic 16-bit oversampling analog-to-digital converter manufactured by Analog Devices Inc. It utilizes a proprietary multistage sigma-delta and pipeline architecture to achieve high dynamic range with selectable decimation factors of 1×, 2×, 4×, or 8×. The device operates on a single +5 V analog supply and a +3 V to +5 V digital supply, consuming power ranging from 150 mW to 585 mW depending on the clock rate. It features an internal programmable reference, differential analog inputs with a nominal full-scale range of 4 V, and parallel CMOS data outputs in a 44-lead MQFP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a three-stage half-band FIR filter providing up to 85 dB stop-band attenuation and minimal pass-band ripple for high-fidelity signal processing.
• Offers flexible power scaling capabilities, allowing operation at reduced power levels when lower clock frequencies are utilized.
• Supports simplified system design through single-supply operation for both analog and digital logic sections.

Analog To Digital Converters (ADC) Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'ASRL' against official manufacturer documentation to confirm temperature grade and packaging configuration. Ensure compatibility with existing board layouts regarding the 44-lead MQFP footprint and thermal requirements. Confirm that the selected decimation mode aligns with the target output data rate specifications.

Analog To Digital Converters (ADC) Selection Notes

Select the appropriate decimation factor based on the required output word rate versus the maximum 20 MHz clock input frequency. Evaluate power consumption constraints to determine if reduced clock rates are viable for achieving lower dissipation. Verify that the differential input voltage range matches the source signal characteristics centered around the common-mode level.
