ISLA224P12IRZ

Analog To Digital Converters (ADC) Overview

The ISLA224P12IRZ is a dual-channel, 14-bit analog-to-digital converter (ADC) from the ISLA224P12 series. It utilizes Intersil’s proprietary FemtoCharge™ technology on a standard CMOS process to achieve sampling rates up to 125MSPS. The device features unbuffered differential inputs and supports selectable digital output formats, including LVDS-compatible or LVCMOS options. Configuration is managed via a serial peripheral interface (SPI) port, allowing control over gain and offset parameters. It operates from a single 1.8V supply and is housed in a 72-contact QFN package with an exposed paddle, rated for industrial temperatures between -40°C and +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRZ' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the design accommodates the 72-contact QFN package requirements, including thermal management for the exposed paddle. Confirm that the SPI interface logic levels match the system controller before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel 14-bit performance at 125MSPS is required. Compare against other ISLA224P variants if higher sampling rates like 200MSPS or 250MSPS are needed. Verify that the unbuffered input requirement fits the signal source impedance. Consider the available digital output format options to simplify interface circuitry.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ISLA224P family of high-speed dual-channel ADCs. The family includes variants with different maximum sampling rates ranging from 130MSPS to 250MSPS. All members share pin compatibility and similar architectural features, differing primarily in speed specifications and resolution options within the 12-bit and 14-bit range.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible upgrades within the ISLA224P series for higher speeds. Verify if alternative manufacturers offer comparable dual-channel 14-bit ADCs with similar SPI configurability and LVDS/CMOS output flexibility.
