LTC2261IUJ-14#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2261IUJ-14#TRPBF is a 14-bit, 125Msps ultralow power analog-to-digital converter (ADC) from Analog Devices. It operates on a single 1.8V supply with typical power dissipation of 127mW at full speed. The device features an 800MHz full-power bandwidth sample-and-hold circuit and ultra-low jitter of 0.17psRMS. Key performance metrics include a signal-to-noise ratio (SNR) of 73.4dB and spurious-free dynamic range (SFDR) of 85dB at 70MHz input. It offers selectable input ranges from 1VP-P to 2VP-P and supports CMOS, DDR CMOS, or DDR LVDS digital outputs.

Analog To Digital Converters (ADC) Feature Summary

• 14-bit resolution with 125Msps sampling rate and 127mW power consumption
• Ultra-low jitter (0.17psRMS) enabling high-performance undersampling
• Selectable analog input ranges: 1VP-P to 2VP-P via SENSE pin
• Optional data output randomizer and clock duty cycle stabilizer

Analog To Digital Converters (ADC) Applications

• Cellular base stations
• Software defined radios
• Portable medical imaging
• Multi-channel data acquisition systems
• Nondestructive testing equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the 'I' grade designation corresponds to the –40°C to 85°C industrial temperature range. Ensure the specific revision matches the required datasheet version for timing characteristics.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 14-bit accuracy at 125Msps with minimal power budget. Consider the LTC2260-14 or LTC2259-14 if lower sampling rates (105Msps or 80Msps) allow for reduced power consumption. Verify that the chosen digital output interface (CMOS vs LVDS) aligns with downstream logic requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2261-14 family of ultralow power ADCs. It shares pin compatibility with 12-bit versions in the same series. The '#TRPBF' suffix specifically denotes the tape and reel packaging format with lead-free finish, distinct from the tube-packaged '#PBF' variant.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2260IUJ-14#TRPBF (105Msps), LTC2259IUJ-14#TRPBF (80Msps). These variants offer lower power consumption at reduced sampling speeds while maintaining pin compatibility.
