LTC2143CUP-14#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2143CUP-14#TRPBF is a dual-channel, 14-bit analog-to-digital converter (ADC) from Analog Devices Inc., operating at a maximum sampling rate of 80Msps. It features simultaneous sampling with an ultralow jitter of 0.08ps RMS and a full-power bandwidth of 750MHz. The device achieves a typical Signal-to-Noise Ratio (SNR) of 72.9dBFS and Spurious Free Dynamic Range (SFDR) of 89dBFS. Powered by a single 1.8V supply, it dissipates approximately 113mW in CMOS mode. Digital outputs are configurable as full-rate CMOS, double data rate CMOS, or double data rate LVDS.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the source document matches the manufacturer's official datasheet for the LTC2143-14 series.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2145-14 or LTC2144-14 if the application requires a lower sampling rate of up to 80Msps. This variant offers reduced power dissipation compared to higher-speed counterparts while maintaining identical 14-bit resolution and dynamic performance specifications.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2145-14/LTC2144-14/LTC2143-14 family of low-power dual ADCs. The specific part number identifies the 80Msps speed grade (LTC2143), commercial temperature range ('C'), QFN package ('UP'), and tape and reel shipping format ('#TRPBF').

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2143CUP-14#PBF is the tube-packaged equivalent. For higher speeds, consider the LTC2144-14 (105Msps) or LTC2145-14 (125Msps). Industrial temperature variants are available as LTC2143IUP-14.
