ISLA224S20IR1Z

Analog To Digital Converters (ADC) Overview

The ISLA224S20IR1Z is a dual-channel, 14-bit analog-to-digital converter (ADC) from the ISLA224S series. It features a pipeline architecture with differential inputs and supports sampling rates up to 200 MSPS. The device utilizes JESD204B compliant high-speed serial output interfaces, offering configurable data lanes. Key electrical specifications include a signal-to-noise ratio of 73.8 dB, integral nonlinearity of +/- 2 LSB, and differential nonlinearity ranging from -0.5 to 1 LSB. It operates on a single 1.8 V supply, dissipates 972 mW, and functions within an industrial temperature range of -40°C to +85°C. The component is housed in a 48-lead QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify export compliance documentation requirements prior to ordering, as this product may require additional files for shipment from the United States. Confirm RoHS status details through official manufacturer channels. Ensure the specific IR1Z suffix matches the required packaging and tape-and-reel specifications for automated assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization and JESD204B compatibility are required alongside 14-bit resolution at 200 MSPS. Compare against the ISLA224P series if parallel or LVDS outputs are preferred over serial links. Verify that the 1.8 V single-supply operation aligns with system power constraints and that the QFN-48 package fits the PCB layout limitations.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ISLA224S family of low-power, high-performance ADCs designed using FemtoCharge technology. It shares the same analog core as the ISLA224P series but differentiates itself through a highly configurable JESD204B transmitter. The series offers pin-compatible options across varying sample rates, providing flexibility for design upgrades while maintaining consistent form factors.

Analog To Digital Converters (ADC) Replacement Considerations

The related model ISLA224S20 is listed as No Recommended Replacements Available (NRND). Designers should verify if the IR1Z suffix implies specific packaging differences compared to standard tray versions. No direct cross-manufacturer substitutes are documented in the provided sources.
