ADS8864IDGSR

Analog To Digital Converters (ADC) Overview

The ADS8864IDGSR is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input architecture and operates with an SPI-compatible serial interface. The device supports sampling rates up to 400 kSPS while maintaining low power consumption of 5.5 mW. It functions within an analog supply voltage range of 2.7 V to 3.6 V and a digital supply range of 1.65 V to 3.6 V. Key performance metrics include a signal-to-noise ratio of 93 dB and a SINAD of 92.9 dB. The component is housed in a compact MSOP-10 package and operates reliably across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Daisy-chainable architecture allows multiple devices to be connected for expanded system capabilities.
• Integrated internal oscillator eliminates the need for external clock sources, simplifying design.
• Miniature MSOP-10 package provides significant board space savings for portable applications.

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation requiring high resolution and low power
• Industrial process control systems utilizing single-ended sensor inputs
• Battery-powered data acquisition modules

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDGSR corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the order quantity aligns with standard reel sizes to avoid partial reel handling issues. Ensure compatibility with existing SPI controller logic levels before finalizing procurement decisions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended input configuration is sufficient for the application, as opposed to differential variants like the ADS8864 or ADS8866. The 400 kSPS speed offers a balance between throughput and power efficiency. Consider the external reference requirement, as this model does not integrate an internal voltage reference unlike some other ADC families.

Analog To Digital Converters (ADC) Part Context

This part belongs to the microPOWER family of SAR ADCs from Texas Instruments, designed for miniaturized systems. It shares the MSOP-10 footprint and daisy-chain capability with peers such as the ADS8860 and ADS8866. The primary distinction lies in its specific combination of 16-bit resolution, 400 kSPS speed, and single-ended input structure.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8860IDGSR serves as a functional substitute within the same series, offering identical pinout and interface characteristics. Designers should verify that the alternative part's input type and sampling rate specifications meet the original circuit requirements without modification.
