LTC2392ILX-16#PBF

Overview

The LTC2392ILX-16#PBF is a 16-bit, 500ksps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 5V supply and supports a ±4.096V fully differential input range. The device features an internal precision reference with ±20ppm/°C max temperature coefficient and guarantees 16-bit no missing codes. Key performance metrics include a typical SNR of 94dB at fIN = 20kHz, ±2LSB max INL, and 110mW power dissipation at full throughput. It offers both parallel and serial interface modes with no pipeline delay or cycle latency.

Feature Summary

• 16-bit resolution with guaranteed no missing codes and ±2LSB max INL
• 500ksps throughput rate with internal oscillator for conversion timing
• Single 5V supply operation with 1.8V to 5V I/O voltage compatibility
• Internal 4.096V reference with 0.5% initial accuracy and ±20ppm/°C tempco

Applications

• Medical Imaging
• High Speed Data Acquisition
• Digital Signal Processing
• Industrial Process Control
• Instrumentation

Procurement Notes

Verify the specific ordering suffix ILX corresponds to the 48-lead LQFP package and the -I grade indicating an operating temperature range of –40°C to 85°C. Confirm that the #PBF designation indicates lead-free finish and tray packaging as per the manufacturer's standard definitions for this part number.

Selection Notes

Select the LTC2392ILX-16#PBF when a 500ksps sampling rate and 16-bit resolution are required within a 7mm × 7mm LQFP footprint. Ensure the application can accommodate the 110mW power dissipation at maximum speed. Consider the internal reference specifications if external precision references are not utilized in the design.

Part Context

This component belongs to the LTC2392-16 family of low noise, high-speed SAR ADCs. The 'I' suffix denotes the industrial temperature grade (-40°C to 85°C), while 'LX' specifies the 48-lead plastic LQFP package. It is distinct from the UK package variants and other speed grades like the LTC2393-16 (1Msps) or LTC2391-16 (250ksps).

Replacement Considerations

Direct pin-compatible replacements within the same package and temperature grade include the LTC2392CLX-16#PBF (commercial grade, 0°C to 70°C) and the LTC2392HLX-16#PBF (extended grade, –40°C to 125°C). Verify thermal requirements before substituting.
