Overview
The LTC2400CS8#TRPBF is a micropower 24-bit delta-sigma analog-to-digital converter in an 8-lead SOIC package. It operates on a single 2.7V to 5.5V supply with a typical conversion current of 200µA and sleep current of 20µA. The device features an internal oscillator, eliminating external frequency-setting components, and provides better than 110dB rejection at 50Hz or 60Hz. It accepts reference voltages from 0.1V to VCC and supports an extended input range of –12.5% to 112.5% of VREF. The converter delivers 4ppm INL, 0.3ppm RMS noise, and communicates via a flexible 3-wire SPI-compatible interface.
Feature Summary
- 24-bit resolution with no missing codes, 4ppm INL, and 0.3ppm RMS noise
- Internal oscillator requiring no external components for 50Hz/60Hz notch filtering
- Extended input voltage range from –0.125•VREF to 1.125•VREF
- Single-cycle settling time suitable for multiplexed applications
Applications
- Direct temperature measurement
- Strain-gage transducers
- Gas analyzers
- Industrial process control
- 6-digit digital voltmeters
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the component meets RoHS compliance requirements for the intended deployment environment.
Selection Notes
Select this model for high-resolution applications requiring low power consumption and minimal external component count. The internal oscillator simplifies design by removing the need for crystals. Ensure the application voltage stays within the 2.7V to 5.5V range and consider the 8-lead SOIC package constraints for PCB layout.
Part Context
This part belongs to the LTC2400 family of micropower ADCs. The CS8 designation identifies the commercial temperature grade (0°C to 70°C) and the SO-8 plastic package. The #TRPBF suffix specifies the reel packaging format and lead-free status.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin compatibility and electrical specifications before considering any alternative components.
