Overview
The LTC2393HLX-16 is a 16-bit, 1Msps Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc. It features a fully differential input architecture with an internal reference and operates from a single 5V analog supply. The device offers high dynamic performance, including a Signal-to-Noise Ratio (SNR) of 94dB and a Spurious-Free Dynamic Range (SFDR) of 104dB. It supports both parallel and serial CMOS/LVDS output interfaces and is housed in a 48-lead LQFP package.
Feature Summary
- Supports large ±4.096V fully differential input range for maximum dynamic range
- Integrates low noise internal reference to reduce external component count
- Provides flexible data output via selectable parallel or serial interfaces
- Operates from a single 5V power supply
Applications
- High-performance industrial process control systems
- Medical imaging equipment requiring high dynamic range
- Test and measurement instrumentation
- Data acquisition systems demanding low noise and high speed
Procurement Notes
Verify the specific suffix 'HLX' against official Analog Devices documentation to confirm temperature grade and packaging type. Ensure compatibility with the intended operating environment specifications. Confirm interface requirements for parallel or serial mode selection during system design. Check for availability of evaluation boards such as DC1501A for performance validation.
Selection Notes
Select this component when a 16-bit resolution and 1Msps sampling rate are required with low noise characteristics. The internal reference simplifies board layout compared to external reference designs. Consider the LQFP-48 package constraints for PCB routing. Evaluate the need for differential inputs versus single-ended alternatives if cost or pin count is a primary constraint.
Part Context
The LTC2393-16 belongs to a family of low-noise, high-speed SAR ADCs that includes variants like the LTC2392-16 (500ksps) and LTC2391-16 (250ksps). These devices share similar architectural features but differ in sampling rates. The family is designed for applications requiring high linearity and wide dynamic range from a single 5V supply.
Replacement Considerations
LTC2392CLX-16#PBF: Lower sampling rate (500ksps), same resolution and package. LTC2391CLX-16#PBF: Lower sampling rate (250ksps), same resolution and package. LTC2378-16: Different package and potentially different performance metrics.
