LTC2372HUH-16#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2372HUH-16#TRPBF is an 8-channel, 16-bit successive approximation register (SAR) analog-to-digital converter. It operates from a single 5V supply with a throughput rate of 500ksps per channel. The device features a configurable input multiplexer supporting fully differential, pseudo-differential unipolar, and bipolar ranges. Key electrical specifications include ±1LSB maximum integral nonlinearity, no missing codes at 16 bits, and typical signal-to-noise ratios of 96dB for fully differential and 93.5dB for pseudo-differential configurations. Power dissipation is 27mW at full sampling rate, scaling down to 300μW in sleep mode.

Analog To Digital Converters (ADC) Procurement Notes

Verify the H suffix indicates the extended temperature range of –40°C to 125°C. Confirm the TRPBF suffix denotes tape and reel packaging. Ensure compatibility with the 32-lead 5mm × 5mm QFN footprint during PCB layout. Cross-reference the specific ordering information table for lead-free finish details.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight independent channels are required within a single package. The internal reference eliminates external precision reference requirements. Verify that the 500ksps throughput meets system bandwidth needs. Consider the nap mode for power reduction if the sampling rate is lower than the maximum specification.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2372-16 family of low noise, high-speed SAR ADCs. The HUH variant specifically designates the industrial temperature grade (-40°C to 125°C) and the QFN package type. It shares architectural similarities with the LTC2373 but offers a fixed 500ksps rate compared to higher speed alternatives.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2372IUH-16#TRPBF: Identical electrical performance but limited to –40°C to 85°C operating temperature. LTC2372CUH-16#TRPBF: Commercial grade version with 0°C to 70°C operating range.
