Overview
The LTC2392IUK-16#PBF is a 16-bit, 1Msps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It features an internal reference and operates on a single 5V supply with a typical power dissipation of 125mW. The device provides high performance metrics including a Signal-to-Noise Ratio (SNR) of 94dB, Spurious-Free Dynamic Range (SFDR) of 104dB, and Total Harmonic Distortion (THD) of -102dB. Differential input types are supported within a QFN-48 package.
Feature Summary
- 16-bit resolution with 1Msps sampling rate
- Internal voltage reference for simplified design
- High dynamic performance: 94dB SNR and 104dB SFDR
- Low power consumption: 125mW at 5V supply
Applications
- Portable medical instrumentation
- Industrial process control systems
- Data acquisition systems requiring high precision
Procurement Notes
Verify the manufacturer part number against official Analog Devices documentation to ensure compatibility. Confirm that the specific suffix matches the required temperature grade and packaging format. Cross-reference technical specifications directly with the datasheet to validate electrical parameters for the target application environment.
Selection Notes
Select this component when a 16-bit SAR ADC with integrated reference is required. Ensure the system supports a single 5V analog supply. Verify that the QFN-48 package footprint aligns with the PCB layout constraints. Check thermal requirements as the device dissipates approximately 125mW during operation.
Part Context
This part belongs to the LTC2393 series family, which includes similar 16-bit SAR ADCs. The 'I' suffix typically denotes an industrial temperature range. The '#PBF' suffix indicates lead-free compliance. This specific model is designed for applications needing moderate speed with high accuracy.
Replacement Considerations
Direct replacements within the same family include the LTC2393CUK-16#PBF. Verify pinout and electrical specifications before substitution. Other 16-bit SAR ADCs from Analog Devices may require interface or supply voltage adjustments.
