LTC2376IMS-20#PBF

Analog To Digital Converters (ADC) Overview

The LTC2376IMS-20#PBF is a 20-bit, 250ksps low power successive approximation register (SAR) ADC from Analog Devices Inc. Operating from a single 2.5V supply with an OVDD range of 1.71V to 5.25V, it features a fully differential analog input range of ±VREF, where VREF ranges from 2.5V to 5.1V. The device consumes 5.3mW at full throughput and achieves a maximum INL of ±2ppm with no missing codes at 20 bits. It offers 104dB SNR and -125dB THD at fIN = 2kHz. Key features include digital gain compression, SPI-compatible serial I/O supporting 1.8V to 5V logic, and an internal conversion clock.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and tube packaging. Confirm the IMS suffix corresponds to the industrial temperature range of –40°C to 85°C. Ensure the package type matches the 16-lead plastic MSOP specification. Check for availability of the tape and reel variant (#TRPBF) if required for automated assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high linearity and low power are critical for 20-bit applications. The DGC feature allows driving the ADC from a single positive supply by mapping the input range to 0.1•VREF to 0.9•VREF. Ensure the host system supports the required OVDD voltage levels (1.8V, 2.5V, 3.3V, or 5V) for the digital interface. Verify that the application can accommodate the 250ksps maximum sampling rate.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2376-20 family of 20-bit SAR ADCs. The IMS-20#PBF variant specifically denotes the industrial temperature grade (-40°C to 85°C) in a 16-lead MSOP package. Other variants include the CDE-20#PBF (commercial temp, DFN) and CMS-20#PBF (commercial temp, MSOP). The '20' suffix indicates the 20-bit resolution version of the LTC2376 series.
