LTC2264CUJ-14#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2264CUJ-14#TRPBF is a dual-channel, simultaneous sampling 14-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 40Msps. It features serial LVDS outputs and operates on a single 1.8V supply with typical power dissipation of 113mW. Key performance metrics include a signal-to-noise ratio (SNR) of 73.7dB and a spurious-free dynamic range (SFDR) of 90dB. The device offers selectable input ranges from 1VP-P to 2VP-P, an internal reference, and supports shutdown and nap modes for power management.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel simultaneous sampling with 40Msps throughput
• Serial LVDS outputs with configurable 1-lane or 2-lane modes
• Low jitter of 0.15ps RMS enabling effective undersampling
• Internal 1.25V reference with selectable input ranges

Analog To Digital Converters (ADC) Applications

• Cellular base stations
• Software defined radios
• Portable medical imaging
• Multichannel data acquisition systems
• Nondestructive testing equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'C' suffix indicates a commercial temperature range of 0°C to 70°C. Confirm the '#TRPBF' suffix denotes tape and reel packaging and lead-free finish. Ensure the source document explicitly lists this specific part number as available; generic family datasheets may not reflect current manufacturing status for every speed grade variant.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2265-14 if a 40Msps sampling rate is sufficient, as it offers lower power consumption (113mW vs 171mW). Choose the 'I' suffix version if operation below 0°C is required. Verify that the serial LVDS interface compatibility matches the downstream digital processing unit's requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC226x-14 family, which includes the higher-speed LTC2265-14 (65Msps) and lower-power LTC2263-14 (25Msps). All variants share pin compatibility and architectural similarities, allowing for design flexibility across different bandwidth and power constraints within the same package footprint.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2265IUJ-14#TRPBF serves as a higher-speed alternative within the same package. The LTC2263IUJ-14#TRPBF offers a lower-speed option. Direct substitution requires verifying that the system timing margins accommodate the respective sampling rates and that power budgets align with the new device's dissipation characteristics.
