LTC2480CDD#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2480CDD#TRPBF is a 16-bit delta-sigma analog-to-digital converter featuring Easy Drive technology for automatic cancellation of differential input current. It operates on a single supply voltage ranging from 2.7V to 5.5V and provides a rail-to-rail input common mode range independent of the reference voltage. The device includes an internal oscillator, programmable gain from 1 to 256, and selectable line frequency rejection modes. It utilizes a 4-wire SPI interface and is housed in a 10-lead DFN package.

Analog To Digital Converters (ADC) Feature Summary

• Easy Drive Technology eliminates dynamic input current errors, enabling direct digitization of high impedance sensors with zero differential input current.
• Programmable gain ranges from 1 to 256 in 8 steps, supporting signals as low as 100mV reference voltage.
• Selectable line frequency rejection for 50Hz, 60Hz, or simultaneous 50Hz/60Hz noise suppression.
• Internal trimmed oscillator eliminates the need for external crystals, with a selectable 2x speed-up mode.

Analog To Digital Converters (ADC) Applications

• Direct sensor digitizer
• Weight scales
• Strain gauge transducers
• Industrial process control

Analog To Digital Converters (ADC) Procurement Notes

Verify the C suffix indicates a commercial temperature range (0°C to 70°C) and the DD suffix denotes the 10-lead DFN package. Confirm the #TRPBF suffix specifies tape and reel packaging. Ensure the source document matches the Analog Devices datasheet for the LTC2480 series.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high DC accuracy is required with large external source impedances. The 16-bit resolution and 2ppm INL make it suitable for precision measurements. Consider the H-grade variant if operation above 70°C is necessary.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2480 family of 16-bit ADCs. The CDD variant specifically refers to the commercial grade version in the 3mm x 3mm DFN package. Other variants include IDD for industrial grade and HDD/HMS for extended temperature ranges.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pin compatibility and electrical specifications against alternative 16-bit delta-sigma ADCs if sourcing issues arise.
