Overview
The LTC2393ILX-16 is a 16-bit, 1Msps 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 analog supply and accepts a large ±4.096V fully differential input range. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 94dB, Spurious-Free Dynamic Range (SFDR) of 104dB, and Total Harmonic Distortion (THD) of -102dB. Power dissipation is specified at 125mW. The component is housed in a 48-lead LQFP package.
Feature Summary
- 16-bit resolution with 1Msps sampling rate
- Internal voltage reference with ±4.096V differential input range
- Dual output modes: Parallel (up to 1MHz clock) and Serial SPI (up to 80MHz clock)
- High dynamic performance: 94dB SNR and 104dB SFDR
Applications
- High-performance data acquisition systems requiring maximum dynamic range
- Industrial process control and instrumentation
- Medical imaging equipment
- Test and measurement instruments
Procurement Notes
Verify the specific suffix 'ILX' against the official Analog Devices datasheet to confirm temperature grade and packaging configuration. Ensure compatibility with the required operating temperature range for the target application. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a 16-bit SAR ADC with integrated reference and high speed (1Msps) is required. Compare with LTC2392-16 (500ksps) or LTC2391-16 (250ksps) if lower power consumption is prioritized over sampling speed. Evaluate the need for parallel vs. serial interface based on system bus architecture constraints.
Part Context
The LTC2393ILX-16 belongs to the LTC2393-16 family of low-noise, high-speed ADCs. This family includes variants with different sampling rates, such as the LTC2392-16 and LTC2391-16. These devices are designed for applications demanding high accuracy and wide dynamic range from a single 5V supply.
Replacement Considerations
Direct functional substitutes within the same family include the LTC2392CLX-16#PBF (500ksps) and LTC2391CLX-16#PBF (250ksps), which share the same pinout and interface but offer lower sampling rates. Verify package compatibility (LQFP-48) and electrical specifications before substitution.
