LTC2267CUJ-12#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2267CUJ-12#TRPBF is a dual-channel, simultaneous sampling 12-bit analog-to-digital converter (ADC) from Analog Devices. Operating at a maximum sampling rate of 105Msps, it features an ultralow jitter of 0.15ps RMS and a full power bandwidth of 800MHz. The device delivers a typical Signal-to-Noise Ratio (SNR) of 70.6dB and a Spurious Free Dynamic Range (SFDR) of 88dB. It integrates internal references and supports selectable input ranges of 1VP-P to 2VP-P. Digital outputs utilize serial LVDS with configurable 1-lane or 2-lane modes. Powered by a single 1.8V supply, the total power dissipation is typically 238mW. The component is housed in a 40-lead QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the #TRPBF suffix indicates Tape and Reel packaging, distinct from the #PBF Tube variant. Confirm the 'C' grade designation corresponds to the commercial operating temperature range of 0°C to 70°C. Ensure the source documentation explicitly lists this part number as lead-free and RoHS compliant before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2267CUJ-12#TRPBF when a 105Msps sampling rate is required for dual-channel applications. Choose this specific ordering code over the #PBF version if surface-mount reflow assembly via tape and reel is necessary. Verify that the 0°C to 70°C commercial temperature range meets the system environmental requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2267-12 series, which includes variants with different sampling speeds such as the LTC2268-12 (125Msps) and LTC2266-12 (80Msps). All members share pin compatibility and architectural similarities within the 40-lead QFN package family. The CUJ-12#TRPBF specifically denotes the commercial temperature grade packaged in a tape and reel format.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2267IUJ-12#TRPBF serves as a direct replacement for extended industrial temperature operation (-40°C to 85°C). For higher speed requirements, the LTC2268CUJ-12#TRPBF offers 125Msps performance. For lower power needs, the LTC2266CUJ-12#TRPBF provides 80Msps operation.
