ADS8168IRHBT

Analog To Digital Converters (ADC) Overview

The ADS8168IRHBT is a high-speed, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It integrates an 8-channel multiplexer with a sample-and-hold circuit and the ADC core within a single device. The component supports sampling rates up to 1 MSPS and features a serial peripheral interface (SPI) for data output. It operates with an analog supply voltage ranging from 3 V to 5.5 V and a digital supply voltage between 1.65 V and 5.5 V. The device is housed in a 32-pin VFQFN package measuring 5 mm by 5 mm, designed for surface-mount installation.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel input multiplexer with individual sample-and-hold circuits for each channel
• Supports pseudo-differential or single-ended input configurations
• Features an internal oscillator to simplify system design
• Provides enhanced SPI compatibility for digital communication

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Data acquisition modules for automated testing equipment
• Medical instrumentation involving physiological signal monitoring
• Vibration analysis and condition monitoring systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct package type and temperature rating. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the supplier provides valid traceability documentation matching the original manufacturer's part identification codes.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight independent channels require simultaneous sampling capabilities at 16-bit resolution. Evaluate power consumption constraints regarding the separate analog and digital supply domains. Consider the 32-VQFN footprint dimensions during PCB layout planning to accommodate thermal dissipation requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS816x family of SAR ADCs, which includes variants like the ADS8166 and ADS8167. These devices share similar architectural foundations but differ in sampling speeds and feature sets. The ADS8168 specifically targets applications needing higher throughput compared to lower-speed counterparts in the same series.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8166IRHBT: Offers identical pinout and functionality but operates at a reduced sampling rate of 250 kSPS instead of 1 MSPS.
