LTC2376IMS-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2376IMS-16#PBF is a 16-bit, 250ksps low power successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. Operating from a single 2.5V supply, it features a fully differential input range of ±VREF with VREF ranging from 2.5V to 5.1V. The device achieves ±0.5LSB maximum integral nonlinearity, guaranteed 16-bit no missing codes, and typically delivers 97dB SNR at an input frequency of 2kHz. Power consumption is 3.4mW at full throughput, scaling down to 3.4µW in power-down mode. It includes a digital gain compression function and supports SPI-compatible serial interfaces with daisy-chain capability.

Analog To Digital Converters (ADC) Procurement Notes

Verify the IMS suffix indicates an industrial temperature range of –40°C to 85°C. Confirm package type is 16-lead MSOP. Check RoHS compliance status via manufacturer documentation. Ensure ordering suffix #PBF denotes lead-free finish. Validate availability through designated sales channels as distribution may vary.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-bit accuracy and 250ksps throughput are required with minimal power dissipation. The DGC feature simplifies driver amplifier design by allowing single-supply operation. Ensure the host interface voltage matches the OVDD range of 1.71V to 5.25V. Consider the MSOP package constraints for thermal management if operating near the upper temperature limit.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2376-16 family of SAR ADCs. Variants include CMS (commercial), IMS (industrial), and HMS (extended industrial) temperature grades. Package options include 16-lead MSOP and 4mm × 3mm DFN. The IMS grade specifically covers –40°C to 85°C operation, distinguishing it from commercial and extended industrial counterparts.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes within the same family include LTC2376CMS-16#PBF for commercial temperature ranges and LTC2376HMS-16#PBF for extended industrial ranges. These parts share identical pinouts and electrical specifications but differ in operating temperature limits.
