LTC2376IDE-20#PBF

Analog To Digital Converters (ADC) Overview

The LTC2376IDE-20#PBF is a 20-bit, 250ksps low power successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. Operating from a single 2.5V supply with an I/O range of 1.71V to 5.25V, it features a fully differential input range of ±VREF and supports reference voltages from 2.5V to 5.1V. The device achieves a typical SNR of 104dB at 2kHz input frequency and guarantees no missing codes at 20 bits. It dissipates 5.3mW at maximum sampling rate and includes a digital gain compression function to simplify driver amplifier requirements.

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 temperature grade 'I' corresponds to the –40°C to 85°C operating range as listed in the order information table. Ensure compatibility with the 16-lead DFN package dimensions before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 20-bit linearity and 250ksps speed are required within a low power budget. The DGC feature is critical if the application requires driving the ADC from a single positive supply without a negative rail for the buffer amplifier. Verify that the host system supports the SPI timing constraints, specifically the SCK period and CNV pulse widths.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2376 family of high-performance SAR ADCs. The IDE suffix denotes the industrial temperature range (–40°C to 85°C) and the DE package code identifies the 16-lead (4mm × 3mm) plastic DFN form factor. Other variants in the series include CMS and IMS packages with different thermal characteristics and temperature grades.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing should be performed carefully, ensuring that replacement devices match the 20-bit resolution, 250ksps sampling rate, and DFN package footprint.
