ISLA118P50IRZ

Analog To Digital Converters (ADC) Overview

The ISLA118P50IRZ is an 8-bit, 500MSPS analog-to-digital converter manufactured by Renesas Electronics Corporation. It utilizes two time-interleaved 250MSPS unit ADCs to achieve a total sample rate of 500MSPS. The device features a 1.15GHz analog input bandwidth and operates with internal reference voltage. Power supply requirements are 1.7V to 1.9V for both analog and digital sections. It supports differential inputs and offers selectable LVDS or CMOS output formats. The component is housed in a 72-contact QFN package (10x10mm) with an exposed paddle and functions within an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Intersil Interleave Engine (I2E) performs automatic fine correction of offset, gain, and sample time skew mismatches between unit ADCs without external algorithms.
• Serial Peripheral Interface (SPI) port allows extensive configurability of the ADC and control of interleave correction circuitry.
• Supports programmable gain, offset, and skew control along with over-range indicator and clock phase selection.
• Includes nap and sleep modes for power management and provides selectable data formats including Two's Complement, Gray Code, or Binary.

Analog To Digital Converters (ADC) Applications

• High-speed signal acquisition systems requiring low jitter performance
• Test and measurement equipment utilizing high sample rates
• Wireless infrastructure base stations

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix IRZ against the manufacturer's current datasheet to confirm RoHS3 compliance and lead-free status. Confirm the package type remains 72-QFN (10x10) as listed in official documentation. Check for any Product Change Notifications (PCN) regarding label updates or assembly site transfers that may affect part identification or sourcing logistics.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution at 500MSPS is required with integrated interleaving calibration. Ensure the design accommodates the 1.7V to 1.9V dual power supply requirement. Verify that the system can support the SPI configuration interface and the selected digital output format, either LVDS or CMOS, based on downstream logic compatibility.

Analog To Digital Converters (ADC) Part Context

The ISLA118P50 is part of the ISLA118 family of high-speed ADCs. It serves as an upgrade to the KAD551XP-50 product family, maintaining pin similarity while offering improved performance through FemtoCharge technology. It shares the 72-QFN footprint with other variants in the series, such as the 10-bit and 12-bit versions, facilitating potential portfolio scalability.

Analog To Digital Converters (ADC) Replacement Considerations

The manufacturer lists ISLA118P50 as NRND (No Recommended Replacements Available). No direct alternative product is currently available from Renesas for new designs. Existing designs must continue using this part number or evaluate non-pin-compatible alternatives if redesign is feasible.
