LTC2144IUP-14#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2144IUP-14#TRPBF is a dual-channel, 14-bit analog-to-digital converter (ADC) operating at a sampling rate of 105Msps. It features simultaneous sampling with ultralow jitter of 0.10ps RMS for differential encode modes. The device delivers a typical signal-to-noise ratio (SNR) of 72.8dB and a spurious-free dynamic range (SFDR) of 89dB at 70MHz input frequency. Power consumption is 149mW total (75mW per channel) under standard conditions. It operates on a single 1.8V supply and supports full-rate CMOS, double data rate (DDR) CMOS, or DDR LVDS digital outputs.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging when sourcing components. Confirm the I-grade designation ensures operation within the –40°C to 85°C temperature range. Cross-reference the manufacturer part number with official distributor catalogs to ensure authenticity and correct lot traceability.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2145-14 if a 105Msps sampling rate is sufficient, as it offers lower power dissipation (149mW vs 189mW). Choose the LTC2143-14 variant only if an 80Msps rate meets system requirements for further power reduction. Ensure the digital interface mode (CMOS or LVDS) aligns with downstream FPGA or processor capabilities.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC214x-14 family of low-power dual ADCs. It shares the same 64-pin QFN package and pinout structure as the LTC2145-14 and LTC2143-14. The primary distinction across the family is the maximum sampling speed, allowing designers to optimize power consumption against bandwidth needs.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2145IUP-14#TRPBF offers higher speed (125Msps) but increased power. LTC2143IUP-14#TRPBF provides lower speed (80Msps) and reduced power. Both are pin-compatible replacements within the same package.
