ISLA212P20IRZ

Analog To Digital Converters (ADC) Overview

The ISLA212P20IRZ is a high-speed, single-channel analog-to-digital converter (ADC) manufactured by Renesas Electronics. It features a pipeline architecture with a resolution of 12 bits and a maximum sampling rate of 200 MSPS. The device operates on a single 1.8 V supply for both analog and digital domains, consuming approximately 468 mW of power. It accepts differential analog inputs and provides LVDS-compatible parallel digital outputs. Key performance metrics include a signal-to-noise ratio (SNR) of 70.5 dB, a differential nonlinearity (DNL) of 0.9 LSB, and an integral nonlinearity (INL) of 1.8 LSB. The component is housed in a QFN-7 package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• High-speed 200 MSPS sampling capability with 12-bit resolution for precise data acquisition.
• Single 1.8 V power supply design simplifies system power management.
• Internal voltage reference eliminates the need for external precision references.
• LVDS output interface ensures low-power, high-speed digital data transmission.

Analog To Digital Converters (ADC) Applications

• Wireless infrastructure base stations
• Test and measurement equipment
• Medical imaging systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRZ' to confirm the RoHS-compliant, lead-free tray packaging variant. Confirm the 200 MSPS speed grade against the required system timing specifications. Ensure the QFN-7 package footprint matches the PCB layout constraints. Validate that the 1.8 V supply rails are stable within the specified tolerance for optimal SNR performance.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-linearity ADC is required at 200 MSPS. Compare against the ISLA212P25IRZ if a higher 250 MSPS sampling rate is necessary. Consider the internal reference feature if board space for external references is limited. Ensure the host processor supports the parallel LVDS interface timing requirements for reliable data capture.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ISLA212P25 family of high-performance ADCs. The family shares identical architectural features, including the 12-bit pipeline structure and 1.8 V operation. The primary distinction between variants in this series is the maximum sampling rate, with the P20 variant offering 200 MSPS compared to the 250 MSPS of the P25 variant.

Analog To Digital Converters (ADC) Replacement Considerations

The ISLA212P25IRZ is a functional pin-compatible alternative with a higher sampling rate of 250 MSPS. Verify that the system timing margins can accommodate the increased speed if used as a drop-in replacement.
