LTC2217CUP#PBF

Analog To Digital Converters (ADC) Overview

The LTC2217CUP#PBF is a 16-bit, 105Msps low noise analog-to-digital converter (ADC) designed for high-frequency applications. It features a fixed 2.75V peak-to-peak input range and supports input frequencies up to 400MHz. Key performance metrics include an 81.3dBFS noise floor, 100dB spurious-free dynamic range (SFDR), and 85fs RMS aperture jitter. The device operates on a single 3.3V supply with a power dissipation of 1.19W in CMOS mode. It offers flexible digital outputs via LVDS or single-ended CMOS formats.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free finish and tube packaging when sourcing. Confirm the 'C' grade designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the QFN-64 package dimensions match the PCB footprint requirements before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component for systems requiring high linearity and low noise at 105Msps. The internal reference simplifies design but requires careful bypassing. Consider the LVDS option if signal integrity over long traces is critical, or CMOS for lower power consumption. Verify that the 2.75Vpp input range matches the source signal amplitude.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2217 family of high-speed ADCs. It is pin-compatible with the LTC2208, facilitating upgrades or replacements in existing designs. The device integrates a pipeline ADC core, correction logic, and output drivers within a compact 9mm x 9mm QFN package.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2208 is a pin-compatible alternative within the same family. Verify that the replacement meets the required 16-bit resolution and 105Msps speed specifications.
