LTC2392HLX-16

Overview

The LTC2392HLX-16 is a 16-bit, 500ksps Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc. It features an internal reference and supports both parallel and serial digital interfaces. The device operates from a single 5V supply and offers a fully differential input range of ±4.096V. Key performance metrics include a Signal-to-Noise and Distortion Ratio (SINAD) of 95dB and a Spurious-Free Dynamic Range (SFDR) of 110dB. It is housed in a 48-lead LQFP package and is designed for high-performance applications requiring low noise and wide dynamic range.

Part Context

The LTC2392HLX-16 belongs to the LTC239x family of low-noise, high-speed SAR ADCs. This family includes the LTC2391-16 (250ksps), LTC2392-16 (500ksps), and LTC2393-16 (1Msps). These devices share similar pinouts and electrical characteristics, differing primarily in maximum sampling speed. The 'H' suffix typically denotes an extended temperature range or specific grade variant within the Linear Technology/Analog Devices portfolio, though specific thermal limits require datasheet verification.

Replacement Considerations

Direct pin-compatible replacements within the same family include the LTC2391HLX-16 (lower speed, 250ksps) and LTC2393HLX-16 (higher speed, 1Msps). Designers should verify that the system timing requirements align with the selected sampling rate. External references may be used if higher precision than the internal reference is required, but this affects power consumption and board space.
