LTC2372CUH-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2372CUH-16#PBF is an 8-channel, 16-bit successive approximation register (SAR) analog-to-digital converter with a throughput rate of 500ksps. It operates from a single 5V supply and features a configurable input multiplexer supporting fully differential, pseudo-differential unipolar, and bipolar ranges. The device achieves ±1LSB maximum integral nonlinearity (INL) with no missing codes at 16 bits. Typical signal-to-noise ratio (SNR) is 96dB for fully differential and 93.5dB for pseudo-differential configurations. It includes an onboard 2.048V temperature-compensated reference, a programmable sequencer, and dissipates 27mW at full sampling rate.

Analog To Digital Converters (ADC) Feature Summary

• 8-Channel Multiplexer with selectable input ranges: Fully Differential (±4.096V), Pseudo-Differential Unipolar (0V to 4.096V), and Bipolar (±2.048V)
• High Accuracy: ±1LSB Maximum INL, No Missing Codes at 16-Bit Resolution
• Integrated Reference: Onboard 2.048V reference with low drift (20ppm/°C max) and single-shot capable buffer
• Programmable Sequencer: Depth of 16 for automated channel scanning via SPI-compatible interface

Analog To Digital Converters (ADC) Applications

• Programmable Logic Controllers
• Industrial Process Control
• High Speed Data Acquisition
• Portable or Compact Instrumentation
• Automated Test Equipment (ATE)

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type is the 32-lead 5mm × 5mm Plastic QFN. Confirm the temperature grade corresponds to the 'C' suffix, indicating operation from 0°C to 70°C. Ensure the ordering suffix '#PBF' denotes lead-free finish and tube packaging. Cross-reference the manufacturer part number with Analog Devices documentation to confirm pinout compatibility.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel multiplexed ADC is required with 16-bit resolution and 500ksps throughput. It is suitable for applications needing flexible input range configuration without external multiplexers. Consider the internal reference if system cost and board space are constraints. Verify that the 5V analog supply and 1.8V–5V digital I/O requirements match the system architecture.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2372-16 family of 16-bit SAR ADCs. The 'C' in the part number specifies the commercial temperature range (0°C to 70°C). Higher temperature grades are available as the LTC2372IUH-16 (-40°C to 85°C) and LTC2372HUH-16 (-40°C to 125°C). All variants share the same electrical specifications and pinout within their respective temperature ranges.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include the LTC2372IUH-16#PBF for extended industrial temperature range and the LTC2372HUH-16#PBF for automotive/high-temperature environments. These parts are electrically identical but differ in operating temperature limits. Other family members like the LTC2374 offer higher speeds but fewer channels.
