ADS8863IDGSR

Analog To Digital Converters (ADC) Overview

The ADS8863IDGSR is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a true-differential input architecture and operates at a sampling rate of 680 kSPS. The device utilizes a serial peripheral interface (SPI) for data communication. It supports an analog supply voltage range of 2.7 V to 3.6 V and a digital supply voltage range of 1.65 V to 3.6 V. The component is housed in a 10-lead MSOP package and is rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Feature Summary

• True-differential input configuration for improved noise rejection
• Integrated internal oscillator reduces external component count
• Daisy-chainable capability allows multiple devices to share the SPI bus

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation
• Industrial process control systems
• Battery-powered data acquisition systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDGSR indicates the reel packaging format when sourcing. Confirm that the external reference voltage requirements match the system design, as this model does not include an internal reference. Ensure ESD protection protocols are followed during handling due to the small form factor.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and high-speed conversion near 700 kSPS are required with differential inputs. Compare against the ADS8861 if higher speed is needed or the ADS8867 if lower power consumption at reduced speeds is prioritized. Verify that the MSOP-10 package fits the available PCB space constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the microPower family of SAR ADCs from Texas Instruments. It shares the same MSOP-10 footprint and SPI interface with other members like the ADS8861 and ADS8867, facilitating pin-compatible upgrades or downgrades within the same series based on performance needs.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8861IDGSR offers similar functionality but with a higher sampling rate of 1 MSPS. The ADS8867IDGSR provides a lower power alternative with a 100 kSPS rate. Both maintain the 16-bit resolution and differential input structure.
