LTC2367CDE-18#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2367CDE-18#TRPBF is an 18-bit, 500ksps pseudo-differential unipolar SAR ADC in a 16-lead (4mm × 3mm) plastic DFN package. Operating from a 2.5V supply with a VREF range of 2.5V to 5.1V, it achieves ±2.5LSB INL maximum and no missing codes at 18 bits. The device delivers a typical SNR of 97dB and consumes 6.8mW at full throughput. It features an internal oscillator, SPI-compatible serial interface supporting 1.8V to 5V logic, and daisy-chain mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the C-grade temperature rating (0°C to 70°C) matches system requirements. Confirm the DFN package footprint aligns with PCB layout constraints. Ensure OVDD voltage levels are compatible with the host digital interface. Check that the reference voltage remains within the 2.5V to 5.1V operating range for optimal performance.

Analog To Digital Converters (ADC) Selection Notes

Select this part for applications requiring high resolution and speed with low power consumption. The C-grade variant is suitable for commercial environments. For extended temperature ranges, consider the I-grade (-40°C to 85°C) or H-grade (-40°C to 125°C) equivalents. Ensure the analog input signal fits the pseudo-differential unipolar range relative to the chosen VREF.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2367 family of low noise, low power, high speed SAR ADCs. The 'C' suffix indicates the commercial temperature grade, while 'DE' specifies the 16-lead DFN package. The '#TRPBF' suffix denotes tape and reel packaging with lead-free finish. Other variants include MSOP packages and different temperature grades.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other LTC2367-18 variants with different packages or temperature grades, such as LTC2367CMS-18 or LTC2367IDE-18. Verify pin compatibility and electrical specifications before substitution. Consult manufacturer documentation for non-standard lead-based finishes if required.
