LTC2392IUK-16#TRPBF

Overview

The LTC2392IUK-16#TRPBF 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 a typical signal-to-noise ratio (SNR) of 94dB at a 20kHz input frequency and guarantees no missing codes at 16 bits with a maximum integral nonlinearity (INL) of ±2LSB. An internal precision reference provides a nominal 4.096V output with a maximum temperature coefficient of ±20ppm/°C. Power dissipation is 110mW at full throughput.

Feature Summary

• 500ksps throughput rate with no pipeline delay or cycle latency
• Guaranteed 16-bit resolution with no missing codes and ±2LSB max INL
• Internal 4.096V reference with ±20ppm/°C max temperature coefficient
• Parallel and serial interface modes with 1.8V to 5V I/O voltages

Applications

• Medical imaging systems
• High-speed data acquisition
• Digital signal processing
• Industrial process control
• Automated test equipment (ATE)

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the I-grade designation corresponds to the –40°C to 85°C operating temperature range. Ensure the QFN package dimensions match the PCB footprint requirements. Check for lead-free compliance documentation if required by specific manufacturing standards.

Selection Notes

Select this component when a high dynamic range is required with a single 5V supply. The internal reference simplifies design but external references can be used for higher accuracy. Consider the 48-lead QFN package for space-constrained designs. Verify that the 110mW power dissipation fits within the thermal budget of the application environment.

Part Context

This part belongs to the LTC2392-16 family, which includes variants with different sampling rates such as the LTC2391-16 (250ksps) and LTC2393-16 (1Msps). All members share similar architectural features, including the SAR structure and differential input capabilities. The IUK-16 variant specifically denotes the industrial temperature grade in the QFN package.

Replacement Considerations

The LTC2392CLX-16#PBF serves as a commercial grade alternative in an LQFP package. The LTC2392HLX-16#PBF offers an extended temperature range up to 125°C in an LQFP package. Package differences between QFN and LQFP require re-evaluation of the PCB layout and soldering processes.
