Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging when sourcing. Confirm the I-grade designation corresponds to the -40°C to +85°C operating range. Ensure the specific lot marking matches the datasheet requirements for lead-free finish identification.

Analog To Digital Converters (ADC) Selection Notes

Select this model over the LTC2156 or LTC2157 variants if the application requires a maximum sampling rate of 170Msps rather than 210Msps or 250Msps. Verify that the 1.5VP-P input range and differential LVDS output interface are compatible with the system clock and signal source specifications.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC215x-12 family of dual 12-bit ADCs. It shares pin compatibility with higher-speed versions like the LTC2156-12 and LTC2157-12, as well as 14-bit variants in the same series. The #TRPBF suffix specifically denotes the tape and reel packaging format for automated assembly.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same package include the LTC2156IUP-12#TRPBF and LTC2157IUP-12#TRPBF for higher speed requirements. For lower speed needs, the LTC2141IUP-12#TRPBF offers similar functionality at reduced sampling rates.
