LTC2379HMS-18#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2379HMS-18#TRPBF is an 18-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 2.5V supply with a fully differential input range of ±VREF, where VREF spans 2.5V to 5.1V. The device achieves a maximum integral nonlinearity (INL) of ±2 LSB and guarantees 18-bit no missing codes. Typical dynamic performance includes a signal-to-noise ratio (SNR) of 101.2 dB and total harmonic distortion (THD) of –120 dB at a 2 kHz input frequency. Power consumption is 18 mW at the maximum sampling rate of 1.6 Msps.

Analog To Digital Converters (ADC) Procurement Notes

Verify the H-grade suffix indicates operation up to 125°C. Confirm the #TRPBF suffix denotes tape and reel packaging. Ensure OVDD voltage levels match the host interface logic requirements between 1.8V and 5V.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-speed conversion with low power dissipation. The DGC feature simplifies driver amplifier design by allowing single-supply operation. Verify that the required input common-mode range and reference voltage fall within the specified limits for the target application.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2379-18 series of low-power SAR ADCs. The H-grade variant extends the operating temperature range to 125°C compared to commercial and industrial grades. The MSOP package provides a compact solution for space-constrained designs.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other parts in the LTC2379 family with different temperature grades or packaging options, such as LTC2379IMS-18#TRPBF for industrial grade or LTC2379CDE-18#TRPBF for DFN packaging.
