LTC2418CGN#PBF

Analog To Digital Converters (ADC) Overview

The LTC2418CGN#PBF is a micropower, 24-bit Delta-Sigma analog-to-digital converter featuring 16 single-ended or 8 differential input channels. It operates from a single supply voltage ranging from 2.7V to 5.5V and includes an integrated oscillator with no external components required. Key electrical specifications include 2ppm integral nonlinearity (INL), 0.2ppm RMS noise, and a full-scale bipolar input range of –0.5VREF to 0.5VREF. The device provides better than 110dB differential mode rejection at 50Hz or 60Hz ±2% via the FO pin configuration.

Analog To Digital Converters (ADC) Feature Summary

• 16-channel multiplexer supporting 8/16 single-ended or 4/8 differential inputs
• No latency architecture where the digital filter settles in a single cycle
• Integrated internal oscillator eliminating need for external frequency setting components
• Flexible 4-wire SPI/MICROWIRE compatible digital interface

Analog To Digital Converters (ADC) Applications

• Direct sensor digitization
• Weight scales
• Gas analyzers
• Strain gauge transducers
• Industrial process control

Analog To Digital Converters (ADC) Procurement Notes

Verify the package designation GN corresponds to the 28-lead plastic SSOP form factor. Confirm the temperature grade suffix 'C' indicates operation within the 0°C to 70°C commercial range. Ensure the '#PBF' suffix denotes lead-free finish compliance with RoHS standards before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high channel count multiplexing is required without conversion latency. It is suitable for applications demanding low power consumption, specifically the 4µA autosleep current. Verify that the input common mode range aligns with the GND to VCC specification and that the reference voltage requirements fit the 0.1V to VCC differential range.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2414/LTC2418 family of 24-bit ADCs. The primary distinction between the LTC2414 and LTC2418 is the number of available analog input channels; the LTC2418 provides 16 channels compared to the LTC2414's 8 channels. Both share identical performance characteristics regarding resolution, noise, and power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2414CGN#PBF serves as a direct substitute if only 8 channels are required. For industrial temperature ranges, the LTC2418IGN#PBF variant covers -40°C to 85°C. Tape and reel versions are available as LTC2418CGN#TRPBF.
