LTC2393HLX-16#PBF

Overview

The LTC2393HLX-16#PBF is a high-speed, low-noise 16-bit Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) manufactured by Analog Devices. It operates at a sampling rate of 1 MSPS and supports both parallel and serial output interfaces. The device features an internal reference and runs on a single 5V supply. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 94 dB, a Spurious-Free Dynamic Range (SFDR) of 104 dB, and Total Harmonic Distortion (THD) of -102 dB. It is housed in a 48-lead LQFP package with a power dissipation of 125 mW.

Feature Summary

• 16-bit resolution with 1 MSPS sampling speed
• Low noise architecture: 94 dB SNR and 104 dB SFDR
• Internal voltage reference for simplified design
• Dual interface support: Parallel and Serial CMOS/LVDS

Applications

• High-performance data acquisition systems requiring maximum dynamic range
• Industrial process control applications
• Medical instrumentation
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'H' against official Analog Devices documentation to confirm temperature grade and availability, as standard listings often feature the 'C' variant. Confirm RoHS compliance status via the manufacturer's datasheet. Check for moisture sensitivity levels and recommended storage conditions prior to soldering.

Selection Notes

Select this component when a single-channel, 16-bit ADC with simultaneous parallel/serial output capability is required. Ensure the system can accommodate the LQFP-48 footprint. Compare against the LTC2392-16 or LTC2391-16 if lower sampling rates suffice. Verify that the 5V analog supply aligns with the system power budget.

Part Context

This part belongs to the LTC2393-16 family of low-noise, high-speed ADCs. The family includes variants with different sampling speeds (LTC2392-16 at 0.5 MSPS and LTC2391-16 at 0.25 MSPS). These devices are designed for applications demanding high dynamic range from a single 5V supply.

Replacement Considerations

The LTC2393CLX-16#PBF is a pin-compatible alternative within the same family, differing primarily in the commercial temperature range compared to the industrial/high-temp 'H' grade. Verify thermal specifications before substitution.
