ADS8866IDGS

Analog To Digital Converters (ADC) Overview

The ADS8866IDGS is a single-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 100 kSPS and accepts single-ended input signals. The device utilizes an SPI interface for data communication and requires external voltage references. It functions within an analog supply range of 2.7 V to 3.6 V and a digital supply range of 1.65 V to 3.6 V. The component is housed in a 10-MSOP package and supports operation across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Supports daisy-chainable architecture for multi-channel system expansion
• Integrates an internal oscillator to reduce external component count
• Designed for miniature form factor applications with low power consumption

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring high resolution
• Battery-powered measurement devices
• Industrial process control monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GS' indicates the tube packaging format distinct from the 'GSR' reel variant. Confirm the manufacturer part number matches the exact pinout and electrical specifications required for the design. Ensure compatibility with the intended PCB footprint for the MSOP-10 package before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended input configuration is required rather than differential signaling found in other family members like the ADS8867. Consider the 100 kSPS speed limit against application bandwidth needs. Evaluate the need for external reference circuits as the device does not include an internal reference source.

Analog To Digital Converters (ADC) Part Context

This part belongs to the microPOWER™ ADS8866 series of 16-bit ADCs. It shares architectural similarities with the ADS8860 and ADS8867 but differs in input type and sampling speed variants. The IDGS designation specifies the industrial temperature grade and surface-mount packaging style within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8866IDGSR serves as a functional equivalent differing primarily in tape-and-reel packaging instead of tubes. For differential input requirements, the ADS8867IDGS offers comparable performance with a true-differential front end.
