LTC2341HUH-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2341HUH-16#PBF is a dual-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. Operating from a single 5V supply, it provides simultaneous sampling at 666ksps per channel with an internal reference and buffer. The device features SoftSpan technology, allowing independent per-channel input range configuration of ±4.096V, 0V to 4.096V, ±2.048V, or 0V to 2.048V. It guarantees 16-bit resolution without missing codes, achieving a typical SNR of 93.4dB and INL of ±1.25LSB. The component supports pin-selectable SPI CMOS or LVDS serial interfaces and operates within a temperature range of -40°C to +125°C in a 32-lead QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the H-grade suffix confirms the extended operating temperature range of -40°C to +125°C. Confirm the UH package designation corresponds to the 32-lead (5mm × 5mm) plastic QFN form factor. Ensure compatibility with the required digital I/O voltage levels for either CMOS or LVDS modes before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this model when dual-channel simultaneous sampling is required with flexible input voltage ranges. The H-grade variant is necessary for environments exceeding 85°C. Consider the LVDS interface option if high-speed data transmission over longer traces is needed, or CMOS for lower power consumption in standard logic environments.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC2341-16 family of precision ADCs. The HUH-16#PBF suffix indicates the H-temperature grade (-40°C to +125°C), the UH QFN-32 package, and lead-free finish. It serves as a high-performance solution for multi-channel acquisition systems requiring wide dynamic range and signal chain simplification.
