LTC2376IDE-18#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2376IDE-18#TRPBF is an 18-bit, 250ksps low power SAR ADC from Analog Devices. Operating from a single 2.5V supply, it features a fully differential input range of ±VREF with VREF spanning 2.5V to 5.1V. The device achieves 102dB SNR and ±1.75LSB INL maximum while consuming only 3.4mW at full throughput. It includes a digital gain compression function to simplify driver amplifier requirements. Packaged in a 16-lead DFN (4mm × 3mm), this industrial grade part operates from -40°C to 85°C.

Analog To Digital Converters (ADC) Feature Summary

• 18-bit resolution with guaranteed no missing codes and 102dB typical SNR
• Low power consumption of 3.4mW at 250ksps with auto power-down
• Digital Gain Compression (DGC) eliminates negative supply for drivers
• SPI-compatible serial interface supporting 1.8V to 5V logic levels

Analog To Digital Converters (ADC) Applications

• Medical Imaging
• High Speed Data Acquisition
• Portable or Compact Instrumentation
• Industrial Process Control
• ATE

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging. Confirm the IDE suffix corresponds to the industrial temperature range (-40°C to 85°C) and DFN package. Ensure compatibility with host logic voltages between 1.71V and 5.25V via OVDD.

Analog To Digital Converters (ADC) Selection Notes

Select based on required sampling rate and resolution. The 250ksps rate suits moderate speed applications. Consider the DGC feature if single-supply driving amplifiers are preferred. Verify thermal performance within the DFN package for the specific PCB layout.
