LTC2272IUJ#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2272IUJ#TRPBF is a 16-bit, 65Msps analog-to-digital converter (ADC) featuring a high-speed serial interface compliant with the JESD204 specification. It utilizes a pipeline architecture with an integrated sample-and-hold amplifier offering a 700MHz full-power bandwidth. The device operates on a single 3.3V supply and includes a programmable gain amplifier (PGA) front end to optimize input ranges of either 1.5VP-P or 2.25VP-P. Key performance metrics include a typical spurious-free dynamic range (SFDR) of 100dB and an ultra-low internal jitter of 80fs RMS. The component is housed in a 40-lead, 6mm × 6mm plastic QFN package.

Analog To Digital Converters (ADC) Feature Summary

• 16-bit resolution with a sampling rate of 65Msps
• High-speed serial output interface conforming to JESD204 standard
• Integrated PGA supporting 1.5VP-P or 2.25VP-P differential input ranges
• Ultra-low internal jitter of 80fs RMS for high-frequency undersampling

Analog To Digital Converters (ADC) Applications

• Telecommunications systems
• Cellular base stations
• Spectrum analysis equipment
• Imaging systems
• Automatic test equipment (ATE)

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix #TRPBF confirms lead-free finish and tape and reel packaging. Confirm the 'I' designation indicates an industrial temperature range of –40°C to 85°C. Ensure the specific lot matches the required RoHS compliance standards for the target assembly process.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2273 if a maximum sampling rate of 65Msps is sufficient for the application. Verify that the 16-bit resolution and 100dB SFDR meet the dynamic range requirements. Ensure the system design accommodates the 1100mW power dissipation at full speed and provides adequate thermal management for the QFN package.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC227x family of high-speed serial ADCs. It shares pin compatibility with the LTC2273 (80Msps) and LTC2274 (105Msps). The primary distinction lies in the maximum sample rate, which is limited to 65Msps for the LTC2272 variant compared to higher speeds in other family members.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2273IUJ#TRPBF is a pin-compatible alternative within the same family, offering an increased sampling rate of 80Msps while maintaining identical pinouts and functionality.
