LTC2348CLX-16

Analog To Digital Converters (ADC) Overview

The LTC2348CLX-16 is an octal, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Analog Devices. It operates at a sampling rate of 200ksps per channel with differential inputs and features SoftSpan capability for flexible input range selection. The device integrates an internal reference and serial interface, housed in a 48-lead LQFP package. Key electrical specifications include a maximum power dissipation of 500mW, a signal-to-noise ratio (SNR) of 93.4dB, and a spurious-free dynamic range (SFDR) of 115dB. It supports digital supply voltages of 5V.

Analog To Digital Converters (ADC) Feature Summary

• Octal architecture providing eight independent 16-bit SAR ADC channels
• SoftSpan input range flexibility allowing configurable full-scale ranges
• High linearity performance with 0.9 LSB DNL and 1.25 LSB INL
• Integrated internal voltage reference and serial output interface

Analog To Digital Converters (ADC) Applications

• Multi-channel data acquisition systems
• Industrial process control instrumentation
• Medical equipment requiring multiple sensor inputs
• Automotive test and measurement applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix CLX indicates tape and reel packaging versus tube options. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating temperature range matches system requirements. Check for moisture sensitivity level (MSL) handling precautions during assembly. Validate pin compatibility with existing PCB footprints.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight simultaneous 16-bit conversions are required at moderate speeds. Compare against single-channel alternatives if fewer inputs suffice to reduce cost. Consider the SoftSpan feature if input signals vary significantly in amplitude. Evaluate power consumption constraints as the total dissipation reaches 500mW across all channels.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2348 family of octal SAR ADCs. It shares architectural similarities with the LTC2344 and LTC2335 series but offers distinct sampling rates and pin configurations. The 16-bit resolution variant provides a balance between precision and throughput for general-purpose multi-channel applications.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2348MPUH-16#PBF is a verified alternative within the same product family offering identical functional specifications. Verify package compatibility as the MPH variant may differ in physical dimensions compared to the CLX LQFP form factor.
