LTC2480HMS#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2480HMS#TRPBF is a 16-bit delta-sigma analog-to-digital converter featuring Easy Drive technology for automatic differential input current cancellation. It supports a single supply voltage of 2.7V to 5.5V and offers programmable gain from 1 to 256 in eight steps. The device provides selectable line frequency rejection at 50Hz, 60Hz, or simultaneous 50Hz/60Hz, along with a 2x speed-up mode. Key electrical specifications include a maximum integral nonlinearity of 10ppm of VREF, an offset error of 2.5µV, and a typical supply current of 160µA during conversion. It operates within an extended temperature range of –40°C to 125°C and utilizes a 10-lead MSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Easy Drive Technology eliminates dynamic input current errors, enabling direct digitization of high-impedance sensors with rail-to-rail inputs.
• Programmable gain ranges from 1 to 256, allowing flexible signal conditioning for various sensor types.
• Integrated on-chip trimmed oscillator removes the need for external crystals or oscillators.
• Selectable line frequency rejection modes (50Hz, 60Hz, or simultaneous) ensure accurate data acquisition in noisy environments.

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 specific H-grade temperature rating (-40°C to 125°C) and the MSOP-10 package configuration against design requirements. Confirm that the tape and reel packaging aligns with automated assembly capabilities. Ensure compatibility with the 4-wire SPI interface timing constraints before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high DC accuracy is required for high-impedance sources without external buffering. The H-grade variant is necessary for applications operating above 85°C. Consider the 2x speed mode if higher data rates are needed, noting the trade-off in noise performance compared to normal speed operation.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2480 family of 16-bit ADCs. The 'H' suffix denotes the extended industrial temperature range (-40°C to 125°C), while 'MSE' indicates the 10-lead MSOP package. The '#TRPBF' suffix specifies the tape and reel packaging format and lead-free finish.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2480HMS#PBF is the tube-packaged equivalent of this part number. Other variants in the family include the C-grade (0°C to 70°C) and I-grade (-40°C to 85°C) versions available in both DFN and MSOP packages.
