ADS8863IDGS

Analog To Digital Converters (ADC) Overview

The ADS8863IDGS is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 680 kSPS and features true differential inputs for high-precision signal acquisition. The device utilizes an SPI-compatible serial interface and 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. Packaged in a compact MSOP-10 form factor, it supports external reference voltages and includes an internal oscillator. Key performance metrics include a signal-to-noise ratio of 94 dB and a power consumption of 1.2 mW at full speed.

Analog To Digital Converters (ADC) Feature Summary

• True differential input architecture minimizes common-mode noise and enhances measurement accuracy.
• Integrated internal oscillator eliminates the need for external clock components.
• Daisy-chainable serial interface allows multiple devices to be connected on a single bus.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IDGS confirms the MSOP-10 package and industrial temperature range during sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates before procurement. Ensure the external reference voltage matches the required input range for the application design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 680 kSPS throughput are required in a miniature surface-mount package. Compare against the ADS8867 if a lower 100 kSPS rate is acceptable for reduced power consumption. Ensure the system design accommodates the specified dual-supply voltage requirements for analog and digital sections.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments microPOWER SAR ADC family, designed for battery-operated applications. It shares the MSOP-10 footprint and daisy-chain capability with related models like the ADS8860 and ADS8867, offering a balance between speed, resolution, and physical size for space-constrained designs.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8867IDGS serves as a verified alternative within the same series, offering identical packaging but with a reduced sampling rate of 100 kSPS. Verify pin compatibility and software register configurations when substituting these devices in existing designs.
