Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging and lead-free compliance. Confirm the AC grade corresponds to the specified commercial temperature range of 0°C to 70°C. Ensure the 28-lead SSOP package matches the design footprint requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic range and low distortion at moderate speeds. The internal reference simplifies design but requires bypassing on the VREF and REFCOMP pins. Consider source impedance effects on acquisition time when driving single-ended signals.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1419 family of 14-bit ADCs. Variants include CG (SSOP), CSW (SOIC), and different temperature grades such as C (Commercial) and I (Industrial). The A-grade typically denotes tighter linearity specifications compared to standard grades.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include LTC1419CSW#TRPBF for SOIC packaging or LTC1419IG#TRPBF for industrial temperature range. Verify package dimensions and thermal characteristics when substituting.
