ISLA224P13IRZ

Analog To Digital Converters (ADC) Overview

The ISLA224P13IRZ is a dual-channel, 14-bit analog-to-digital converter (ADC) from the ISLA224P family. It utilizes Intersil’s proprietary FemtoCharge technology on a standard CMOS process to support sampling rates up to 250MSPS. The device features unbuffered differential inputs and operates from a single 1.8V supply. Digital outputs are selectable in DDR LVDS-compatible or LVCMOS formats. Configuration is managed via a serial peripheral interface (SPI) port for gain and offset control. It is housed in a 72-contact QFN package with an exposed paddle and functions within the industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRZ' against the manufacturer's official datasheet to confirm RoHS compliance status and lead-free packaging specifications. Ensure the ordering quantity aligns with the manufacturer's factory pack requirements, as indicated by the 'Tray' packaging designation. Confirm that the 24-week production cycle meets project timelines before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel, 14-bit ADC with sampling rates up to 250MSPS is required. It is suitable for designs needing flexible digital output options between LVDS and CMOS. Verify that the system can accommodate the 72-contact QFN package and that the 1.8V supply voltage matches the design constraints. Ensure the application benefits from the SPI-based configuration capabilities for precise gain and offset adjustments.

Analog To Digital Converters (ADC) Part Context

The ISLA224P13IRZ belongs to the ISLA224P family of dual-channel A/D converters. This portfolio includes pin-compatible variants with resolutions of 12-bit and 14-bit and maximum sample rates ranging from 130MSPS to 250MSPS. The family shares common architectural features, including FemtoCharge technology and SPI configurability, allowing for scalable design implementations across different speed and resolution requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the official datasheet for pin-compatible alternatives within the ISLA224P family, such as the ISLA224P12 or ISLA224P20, which offer different maximum sample rates. Verify that any substitute part maintains the same 72-contact QFN package and 1.8V supply requirements to ensure mechanical and electrical compatibility without redesigning the PCB layout.
