LTC2369IMS-18#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2369IMS-18#TRPBF is an 18-bit, 1.6Msps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. Operating from a single 2.5V supply, it features a pseudo-differential unipolar input range of 0V to VREF, where VREF ranges from 2.5V to 5.1V. The device achieves a typical Signal-to-Noise Ratio (SNR) of 96.5dB and a Total Harmonic Distortion (THD) of –120dB at a 2kHz input frequency. It consumes 18mW at full throughput and includes an internal oscillator for conversion timing. The IMS-18 variant supports an operating temperature range of –40°C to 85°C and is supplied in a 16-lead MSOP package with tape and reel packaging.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #TRPBF confirms the tape and reel packaging format required for automated assembly processes. Confirm the IMS-18 designation corresponds to the industrial temperature grade of –40°C to 85°C. Ensure the specific lot markings align with the lead-free finish specifications provided in the manufacturer's documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 18-bit resolution and 1.6Msps throughput are required within a low-power constraint. The pseudo-differential input architecture is suitable for applications requiring common-mode noise rejection without differential signaling complexity. Ensure the host system provides a stable 2.5V analog supply and a compatible digital I/O voltage between 1.8V and 5V.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2369-18 family of SAR ADCs. The IMS-18#TRPBF specifically denotes the industrial temperature range version packaged in a 16-lead MSOP and shipped in tape and reel. Other variants in the family include commercial (C-grade) and high-temperature (H-grade) options, as well as DFN package configurations.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same package and electrical specification include other suffixes of the LTC2369-18 series, such as the commercial grade LTC2369CMS-18#TRPBF or the extended temperature grade LTC2369HMS-18#TRPBF, provided the operating temperature requirements are met.
