Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'I' grade designation corresponds to the -40°C to +85°C operating temperature range required for the application environment. Ensure compatibility with the 48-lead TSSOP flow-through pinout during board layout planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component for high-speed applications requiring direct IF sampling up to 500MHz. The internal PGA allows optimization of input ranges without external amplifiers. Consider the 1.45W power dissipation for thermal management in the 48-pin TSSOP package. Verify that the digital interface logic levels match the target DSP or FPGA requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1750 family of 14-bit, 80Msps ADCs. The IFW variant specifically denotes the industrial temperature range (-40°C to +85°C) and the 48-lead plastic TSSOP package. The #TRPBF suffix confirms lead-free status and tape-and-reel shipping configuration.

Analog To Digital Converters (ADC) Replacement Considerations

Consult manufacturer documentation for pin-compatible alternatives within the same family. Verify that any substitute maintains the 80Msps sampling rate and 500MHz bandwidth specifications.
