Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade matches the application requirements, as this component is the 65Msps variant within the LTC217x-12 family. Confirm that the commercial temperature range (0°C to 70°C) aligns with the system environment. Ensure the 52-lead QFN footprint and exposed pad soldering requirements are accommodated in the PCB layout design.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring four synchronized channels with high dynamic range. Compare against LTC2171-12 (40Msps) or LTC2170-12 (25Msps) if lower power consumption is prioritized over sampling speed. Verify that the 800MHz full-power bandwidth sample-and-hold circuit meets the signal frequency requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC217x-12 series, which includes pin-compatible variants with different sampling rates. The 'C' suffix indicates the commercial operating temperature range. The '#PBF' designation confirms lead-free finish and RoHS compliance. It serves as a low-power solution for digitizing wideband signals in multi-channel systems.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2171CUKG-12#PBF offers identical pinout and functionality at a reduced 40Msps sampling rate. LTC2170CUKG-12#PBF provides further power reduction at 25Msps. For higher resolution needs, consider the 14-bit LTC2172-14 series, though power consumption will increase significantly.
