LTC2391HLX-16

Overview

The LTC2391HLX-16 is a low noise, high speed 16-bit successive approximation register (SAR) analog-to-digital converter (ADC). 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 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 source with a typical output of 4.096V.

Feature Summary

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

Applications

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

Part Context

The LTC2391HLX-16 belongs to the LTC2391 family of low noise ADCs, which also includes the LTC2392-16 (500ksps) and LTC2393-16 (1MSPS). These devices share similar architectural features but differ in maximum sampling rates. The 'H' suffix typically denotes a higher temperature grade or specific binning within the Analog Devices portfolio, though specific thermal distinctions require datasheet verification. Evaluation boards such as DC1501A are available for this family.

Replacement Considerations

Direct pin-compatible alternatives within the same family include the LTC2392HLX-16 and LTC2393HLX-16, offering higher sampling speeds (500ksps and 1MSPS respectively) while maintaining 16-bit resolution and interface compatibility. Lower speed variants like the LTC2390 series may offer reduced power consumption.
