LTC2376IDE-18#PBF

Analog To Digital Converters (ADC) Overview

The LTC2376IDE-18#PBF is an 18-bit, 250ksps low power SAR ADC from Analog Devices. It operates from a single 2.5V supply and features a fully differential input range of ±VREF with VREF ranging from 2.5V to 5.1V. The device achieves 102dB SNR at fIN = 2kHz and guarantees no missing codes at 18 bits. Power consumption is 3.4mW at 250ksps. It includes a digital gain compression function, SPI-compatible serial interface supporting 1.8V to 5V logic, and internal conversion clock. The component is housed in a 16-lead DFN package and operates within the -40°C to 85°C temperature range.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and tube packaging for this specific part number. Confirm the IDE suffix corresponds to the industrial temperature grade (-40°C to 85°C) and DFN package. Check current availability status as distribution may vary by region.

Analog To Digital Converters (ADC) Selection Notes

Select this model when 18-bit accuracy and 250ksps speed are required with low power constraints. Ensure the host system supports the SPI interface voltages (1.8V to 5V). Consider the Digital Gain Compression feature if single-supply driving amplifiers are preferred. Verify that the 16-lead DFN package fits the PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2376 family of low power SAR ADCs. The 'I' suffix denotes the industrial temperature range (-40°C to 85°C), while 'C' would indicate commercial range (0°C to 70°C). The 'DE' specifies the 16-lead DFN package. Other variants include CMS (MSOP package) and H-grade parts for extended temperature operation up to 125°C.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitutes include LTC2376CDE-18#PBF (commercial temp) and LTC2376HDE-18#PBF (extended temp). For higher speed, consider LTC2378-18 (1Msps). For lower resolution, LTC2376-16 (16-bit) is available.
