LTC2401CMS#TRPBF

Overview

The LTC2401CMS#TRPBF is a micropower, 24-bit analog-to-digital converter (ADC) in a 10-lead MSOP package. It features a single-channel input and utilizes delta-sigma technology with a digital filter architecture that settles in one cycle, eliminating latency for multiplexed applications. The device operates on a single supply voltage from 2.7V to 5.5V with a typical supply current of 200µA. Key specifications include 4ppm INL, 0.6ppm RMS noise, and an extended input range of –12.5% VREF to 112.5% VREF. It offers 110dB minimum rejection at 50Hz or 60Hz via an internal oscillator.

Feature Summary

• 24-Bit Resolution with No Missing Codes
• Single Conversion Settling Time for Multiplexed Applications
• Integrated Oscillator with 110dB Min 50Hz/60Hz Notch Filter
• Extended Input Range: –0.125•VREF to 1.125•VREF

Applications

• Weight Scales
• Direct Temperature Measurement
• Gas Analyzers
• Strain Gauge Transducers
• Industrial Process Control

Procurement Notes

Verify the ordering suffix #TRPBF indicates tape-and-reel packaging. Confirm the CMS8 variant corresponds to the commercial temperature range (0°C to 70°C). Ensure the datasheet matches the specific lot and revision for compliance requirements.

Selection Notes

Select this component for high-precision, low-power applications requiring no latency between conversion and data output. The LTC2401 is suitable for single-channel systems; use the LTC2402 for dual-channel needs. Verify that the required notch frequency (50Hz or 60Hz) aligns with the FO pin configuration options.

Part Context

This part belongs to the LTC2401/LTC2402 family of mPower ADCs. The 'C' suffix denotes the commercial operating temperature range (0°C to 70°C), while 'I' would indicate industrial range (-40°C to 85°C). The '#TRPBF' suffix specifies the reel packaging and lead-free status.
