LTC2260IUJ-14#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2260IUJ-14#TRPBF is a 14-bit, 105Msps ultralow power analog-to-digital converter (ADC) in a 40-lead QFN package. It operates on a single 1.8V supply with typical power dissipation of 106mW. Key performance metrics include 73.4dB SNR and 85dB SFDR at 70MHz input. The device features an internal reference, selectable input ranges from 1VP-P to 2VP-P, and supports full-rate CMOS, DDR CMOS, or DDR LVDS digital outputs. It includes optional data output randomization and clock duty cycle stabilization.

Analog To Digital Converters (ADC) Feature Summary

• High dynamic range: 73.4dB SNR, 85dB SFDR
• Flexible digital interfaces: CMOS, DDR CMOS, or LVDS

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the 'I' grade specifies operation within the -40°C to 85°C temperature range. Ensure the order matches the specific 105Msps speed bin required by the design.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2261-14 if a 105Msps sampling rate is sufficient, as it offers lower power consumption (106mW vs 127mW). Choose the LTC2259-14 variant if the application requires an even lower sampling rate of 80Msps for reduced power usage. Verify that the 1.8V supply voltage aligns with system constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2260-14 series, which provides pin-compatible 14-bit ADC options. It shares the same 40-pin QFN footprint and interface logic with the LTC2261-14 (125Msps) and LTC2259-14 (80Msps), allowing for design flexibility across different bandwidth requirements without PCB layout changes.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2261IUJ-14#TRPBF (125Msps, higher power) and LTC2259IUJ-14#TRPBF (80Msps, lower power) are pin-compatible alternatives within the same family.
