LTC2480IDD#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2480IDD#TRPBF is a 16-bit delta-sigma analog-to-digital converter featuring Easy Drive technology for zero differential input current. It operates on a single supply of 2.7V to 5.5V and includes an internal oscillator, programmable gain (1 to 256), and selectable line frequency rejection (50Hz, 60Hz, or simultaneous). The device offers rail-to-rail input common mode range, no missing codes, and 2ppm INL. It utilizes a 4-wire SPI interface and is housed in a 10-lead DFN package with an industrial temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Feature Summary

• Easy Drive Technology eliminates dynamic input current errors, enabling direct digitization of high-impedance sensors.
• Programmable gain from 1 to 256 with selectable 50Hz, 60Hz, or simultaneous 50Hz/60Hz line frequency rejection.
• Rail-to-rail input common mode range (GND to VCC) independent of the reference voltage.
• Internal trimmed oscillator and automatic offset/full-scale calibration ensure absolute accuracy.

Analog To Digital Converters (ADC) Applications

• Direct sensor digitizers
• Weight scales
• Strain gauge transducers
• Industrial process control instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the IDD suffix corresponds to the –40°C to 85°C industrial temperature grade. Ensure compatibility with the 10-lead DFN footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high DC accuracy with high source impedance inputs without external buffering. Consider the 2x speed mode if higher data rates are needed, noting the trade-off in noise performance. Verify that the required gain settings and line rejection modes align with the signal environment.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2480 family of precision ADCs. The IDD variant specifically denotes the industrial temperature range extension compared to the commercial CDD version. It shares the same core architecture and pinout as other grade variants within the series.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2480CDD#TRPBF serves as a lower-cost alternative for commercial temperature applications (0°C to 70°C). The LTC2480HDD#TRPBF provides extended temperature capability up to 125°C. Both share identical electrical specifications and pinouts.
