ADS8861IDRCR

Analog To Digital Converters (ADC) Overview

The ADS8861IDRCR is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single differential input and operates with an analog supply voltage range of 2.7V to 3.6V and a digital supply voltage range of 1.65V to 3.6V. The device supports a maximum sampling rate of 1MSPS and communicates via a standard SPI interface. It is housed in a 10-VSON package measuring 3x3 mm, suitable for surface-mount applications. The operational temperature range extends from -40°C to 85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed 16-bit SAR ADC with a sample-and-hold amplifier for accurate signal capture.
• Supports flexible power configurations through separate analog and digital supply domains.
• Utilizes a compact 10-pin VSON footprint designed for space-constrained PCB layouts.

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation requiring low power consumption
• Industrial process control systems with isolated sensor interfaces
• Battery-powered data acquisition modules

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IDRCR' against official Texas Instruments documentation to confirm the reel packaging configuration and temperature grade. Ensure compatibility with existing SPI bus protocols and voltage levels during integration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 16-bit resolution and 1MSPS throughput is required within a miniature form factor. Compare against the ADS8862 if pseudo-differential or single-ended inputs are needed instead of truly differential signals. Consider the ADS8867 if a lower sampling rate of 100kSPS suffices for the application to potentially optimize cost or power usage.

Analog To Digital Converters (ADC) Part Context

This device belongs to the microPOWER family of data converters from Texas Instruments. It shares architectural similarities with other members like the ADS8862 and ADS8867, differing primarily in input types and sampling speeds. The IDRCR designation specifically indicates the tape and reel packaging variant of the ADS8861 series.

Analog To Digital Converters (ADC) Replacement Considerations

ADS8861IDRCT serves as a tray packaging alternative with identical electrical characteristics. ADS8861IDGSR offers the same performance in a 10-VSSOP package. For pin-compatible upgrades with different input configurations, consider the ADS8862 or ADS8867 series.
