LTC2391ILX-16

Overview

The LTC2391ILX-16 is a low-noise, high-speed 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Analog Devices. It operates from a single 5V supply and supports a large ±4.096V fully differential input range, making it suitable for applications requiring maximum dynamic range. The device features both parallel and serial digital output interfaces. Key performance metrics include a sampling rate of 250ksps, a typical signal-to-noise ratio (SNR) of 94dB, and a total harmonic distortion (THD) of -103dB at an input frequency of 20kHz. It integrates an internal reference with an initial accuracy of 0.5%.

Feature Summary

16-bit resolution with 250ksps sampling rate
Single 5V power supply operation
±4.096V fully differential input range
Integrated internal voltage reference

Applications

High-performance data acquisition systems
Industrial process control
Medical instrumentation
Test and measurement equipment

Part Context

The LTC2391ILX-16 belongs to the LTC2393-16 family of low-noise ADCs, which also includes the LTC2392-16 (500ksps) and LTC2393-16 (1Msps). These devices share similar architectural characteristics but differ in maximum sampling speeds. The ILX suffix indicates an industrial temperature range and an LQFP package variant compared to other pinouts in the series.

Replacement Considerations

Direct functional replacements within the same family include the LTC2392CLX-16 and LTC2393CLX-16, which offer higher sampling rates (500ksps and 1Msps respectively) while maintaining 16-bit resolution and compatible interface options. Package variations such as the LQFP-48 or QFN-48 may require board layout adjustments.
