LTC2378IMS-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2378IMS-16#PBF is a 16-bit, 1Msps 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 spanning 2.5V to 5.1V. The device achieves a typical signal-to-noise ratio (SNR) of 97dB and total harmonic distortion (THD) of –122dB at an input frequency of 2kHz. It guarantees 16-bit no missing codes and maintains a maximum integral nonlinearity (INL) of ±0.5LSB. Power consumption is 13.5mW at 1Msps sampling rate, scaling down to 13.5µW in power-down mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix IMS indicates the industrial temperature grade (-40°C to 85°C). Confirm package type MSOP-16 matches design requirements. Check RoHS compliance status via manufacturer documentation. Ensure OVDD supply voltage aligns with host interface logic levels between 1.71V and 5.25V.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16-bit accuracy at 1Msps is required with low power constraints. The DGC feature simplifies driver amplifier design by allowing single-supply operation. Ensure the reference voltage range (2.5V to 5.1V) fits the system architecture. Consider the -40°C to 85°C operating range suitable for industrial environments.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2378 family of low-power SAR ADCs. The IMS suffix denotes the Industrial temperature grade variant packaged in a 16-lead MSOP. Other variants include CDE (DFN) and H-grade packages for extended temperature ranges up to 125°C.
