LTC2358HLX-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2358HLX-16#PBF is a buffered octal, 16-bit, 200ksps per channel simultaneous sampling successive approximation register (SAR) analog-to-digital converter. It features differential inputs with a wide common mode range and picoamp-level input leakage. The device operates from a 5V low voltage supply and flexible high voltage supplies, utilizing an internal reference and buffer to support independent per-channel SoftSpan input ranges including ±10.24V, 0V to 10.24V, ±5.12V, and 0V to 5.12V. It supports pin-selectable SPI CMOS and LVDS serial interfaces.

Analog To Digital Converters (ADC) Feature Summary

• Eight buffered simultaneous sampling channels with integrated picoamp-input analog buffers
• Per-channel configurable SoftSpan input ranges for direct digitization of various signal types
• Pin-selectable SPI CMOS and LVDS serial output interfaces for flexible system integration

Analog To Digital Converters (ADC) Applications

• Programmable Logic Controllers
• Industrial Process Control

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific temperature grade suffix against project requirements. The H-grade variant supports extended operating temperatures up to 125°C. Confirm package integrity upon receipt, as the component is supplied in a 48-lead LQFP format. Ensure compatibility with existing board layouts and power supply configurations before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when high voltage differential signals require direct ADC interfacing without external conditioning. The H-grade designation indicates suitability for environments exceeding standard industrial temperature limits. Consider the available SoftSpan ranges to determine if external attenuators are unnecessary. Verify interface requirements to choose between CMOS or LVDS modes based on noise immunity and bus width needs.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2358 family of SoftSpan ADCs, designed for high-performance data acquisition. The HLX-16 variant specifically denotes the 16-bit resolution version packaged in an LQFP-48 form factor with an extended commercial/industrial temperature rating. It serves as a bridge between high-voltage analog sensors and digital processing systems.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2358CLX-16#PBF offers identical electrical specifications but with a restricted operating temperature range of 0°C to 70°C. LTC2358ILX-16#PBF provides an intermediate rating of –40°C to 85°C. Substitution requires verification that the ambient thermal environment remains within the lower grade's specified limits.
