LTC2266CUJ-12#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2266CUJ-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 80Msps, it features a pipeline architecture with serial LVDS outputs. The device supports selectable input ranges from 1VP-P to 2VP-P and includes an internal reference. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 70.6dB and a Spurious Free Dynamic Range (SFDR) of 88dB. It operates on a single 1.8V supply with total power dissipation of 200mW in standard mode. The component is housed in a 40-lead QFN package and is rated for commercial temperatures (0°C to 70°C).

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel simultaneous sampling with 12-bit resolution and 80Msps throughput.
• High dynamic performance: 70.6dB SNR and 88dB SFDR with ultralow jitter of 0.15ps RMS.
• Serial LVDS digital outputs configurable for 1-lane or 2-lane modes to minimize data lines.
• Integrated SPI port for configuration, shutdown, and nap modes.

Analog To Digital Converters (ADC) Applications

• Communications systems
• Cellular base stations
• Software Defined Radios
• Portable medical imaging
• Multichannel data acquisition

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF confirms tape and reel packaging, distinct from the tube-packaged #PBF variant. Confirm the 'C' grade designation corresponds to the 0°C to 70°C operating temperature range required for the specific application environment.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2267-12 or LTC2268-12 if the system requires an 80Msps sampling rate rather than higher speeds. Ensure the design accommodates the 40-pin QFN footprint and that the 1.8V supply rails are stable within the 1.7V to 1.9V recommended operating conditions.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2266-12 family, which shares pin compatibility with 14-bit versions and higher-speed counterparts like the LTC2267-12 and LTC2268-12. The CUJ-12#TRPBF specifically denotes the commercial temperature grade packaged in tape and reel format for automated surface-mount assembly.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2266IUJ-12#TRPBF offers identical electrical specifications but extends the operating temperature range to -40°C to 85°C.
