LTC2260CUJ-12#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2260CUJ-12#TRPBF is a 12-bit, 105Msps sampling analog-to-digital converter (ADC) from Analog Devices. It operates on a single 1.8V supply with typical power dissipation of 103mW. The device features an ultralow jitter sample-and-hold of 0.17psRMS and supports differential or single-ended inputs with selectable ranges of 1VP-P to 2VP-P. Digital outputs are available in full-rate CMOS, double-data rate CMOS, or double-data rate LVDS formats. Key performance metrics include a signal-to-noise ratio (SNR) of 70.8dB and a spurious-free dynamic range (SFDR) of 85dB at 70MHz input frequency.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging rather than tube packaging. Confirm the 'C' grade designation corresponds to the 0°C to 70°C operating temperature range. Ensure the source document explicitly lists this part number as a valid orderable item within the specified package and temperature variant.

Analog To Digital Converters (ADC) Selection Notes

Select the LTC2260CUJ-12#TRPBF for applications requiring 105Msps throughput with low power constraints. Choose this model over the LTC2261-12 if lower speed is acceptable to reduce power dissipation. Verify that the required digital interface mode (CMOS vs LVDS) aligns with the system's receiver capabilities and voltage levels.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2260-12 family, which includes variants with different sampling rates such as the LTC2261-12 (125Msps) and LTC2259-12 (80Msps). All members share pin compatibility and architectural similarities, allowing for design flexibility across different bandwidth requirements while maintaining consistent form factors.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2261IUJ-12#TRPBF serves as a higher-speed alternative within the same package. The LTC2259IUJ-12#TRPBF offers a lower-speed option. Cross-model substitution requires verification of sampling rate compatibility and power budget adjustments.
