LTC2145IUP-14#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2145IUP-14#TRPBF is a dual-channel, 14-bit analog-to-digital converter (ADC) operating at a sampling rate of 125Msps. It features simultaneous sampling with an ultralow jitter of 0.08ps RMS and a full-power bandwidth of 750MHz. The device delivers a typical signal-to-noise ratio (SNR) of 73.1dB and a spurious-free dynamic range (SFDR) of 90dB. Power consumption is 189mW total (95mW per channel) on a single 1.8V supply. It supports selectable input ranges from 1Vp-p to 2Vp-p and offers CMOS, DDR CMOS, or DDR LVDS digital outputs. The component is housed in a 64-lead QFN package.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging rather than tube packaging. Confirm the 'I' grade designation corresponds to the –40°C to 85°C industrial temperature range. Ensure the serial number matches the specific lot requirements for production integration.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2144-14 or LTC2143-14 variants when the maximum 125Msps sampling speed is required. Choose the IUP package for industrial temperature operation (-40°C to 85°C). Verify that the system requires dual-channel simultaneous sampling and can accommodate the 64-pin QFN footprint.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2145-14 family, which includes the LTC2144-14 (105Msps) and LTC2143-14 (80Msps). All variants share identical pinouts, resolution, and AC performance characteristics but differ in maximum sampling frequency and power dissipation levels.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2145CUP-14#TRPBF is the commercial temperature variant (0°C to 70°C). LTC2145IUP-14#PBF is the same electrical part but supplied in tube packaging instead of tape and reel.
