ISLA112P50IRZ

Analog To Digital Converters (ADC) Overview

The ISLA112P50IRZ is a high-performance, low-power 12-bit analog-to-digital converter (ADC) operating at a sampling rate of 500MSPS. It utilizes Intersil's proprietary FemtoCharge technology on a standard CMOS process and features two time-interleaved 250MSPS unit ADCs managed by the Interleave Engine for automatic correction of offset, gain, and skew mismatches. The device offers a 1.15GHz analog input bandwidth and supports digital output data in selectable LVDS or CMOS formats. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 72-lead QFN package with an exposed paddle.

Analog To Digital Converters (ADC) Feature Summary

• Proprietary FemtoCharge technology enables high-speed conversion on standard CMOS processes.
• Automatic fine interleave correction calibration optimizes performance without external algorithms.
• Extensive configurability via serial peripheral interface (SPI) port for dynamic parameter control.
• Supports multiple chip time alignment through synchronous clock divider reset.

Analog To Digital Converters (ADC) Applications

• High-speed signal acquisition systems requiring precise timing alignment
• Test and measurement equipment utilizing programmable test patterns
• Digital communication infrastructure supporting DDR LVDS-compatible outputs

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRZ' against the manufacturer datasheet to confirm RoHS compliance and lead-free status. Confirm the package type matches the 72-lead QFN specification. Ensure the operating voltage requirements align with system power rails before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution at 500MSPS is required with minimal jitter. Consider the available SPI configurability for gain, offset, and skew control. Evaluate the need for LVDS versus CMOS outputs based on downstream logic compatibility and noise immunity requirements.

Analog To Digital Converters (ADC) Part Context

The ISLA112P50 serves as an upgrade to the KAD551XP-50 product family, offering pin compatibility while enhancing performance. It belongs to a portfolio of pin-compatible 8, 10, and 12-bit A/D converters, allowing for design flexibility across different resolution requirements within the same form factor.

Analog To Digital Converters (ADC) Replacement Considerations

The manufacturer lists the ISLA112P50 as No Recommended Replacements Available (NRND). Designers should verify if alternative pin-compatible models from the same series meet current project needs, as no direct substitute is officially recommended for new designs.
