LTC1750CFW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1750CFW#TRPBF is a 14-bit, 80Msps wide bandwidth analog-to-digital converter (ADC) designed for direct IF sampling up to 500MHz. It features an on-chip programmable gain amplifier (PGA) providing selectable input ranges of 2.25Vp-p or 1.35Vp-p. The device delivers 75.5dB SNR and 90dB SFDR with PGA set to 0, powered by a single 5V supply dissipating 1.45W. It utilizes a 48-lead TSSOP package and supports both two's complement and offset binary digital output formats.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix FW#TRPBF corresponds to the 48-pin TSSOP plastic package and tape-and-reel shipping configuration. Confirm the 'C' grade designation aligns with the required commercial operating temperature range of 0°C to 70°C against system thermal constraints.

Analog To Digital Converters (ADC) Selection Notes

Select this component when digitizing wide dynamic range signals at frequencies approaching 500MHz is required. Ensure the application can accommodate the 1.45W power dissipation and provides adequate bypassing for the 5V analog and digital supplies. Verify that the source impedance allows for the specified 500MHz bandwidth.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1750 family of high-speed ADCs. The CF variant denotes the commercial temperature range version housed in a 48-lead TSSOP package. The #TRPBF suffix indicates the reel packaging format and lead-free compliance status.

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 input bandwidth specifications.
