ADS8329IBRSAR

Analog To Digital Converters (ADC) Overview

The ADS8329IBRSAR is a low-power, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended or differential input configuration with an internal sample-and-hold amplifier and operates at a sampling rate of 1 MHz. The device utilizes a serial interface compatible with standard SPI protocols for data communication. It supports a digital supply voltage range of 1.65 V to 5.5 V and an analog supply voltage of 5 V. The component is housed in a 16-pin QFN package measuring 4 mm by 4 mm with an exposed thermal pad, designed for surface-mount installation.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'AR' indicates tape and reel packaging when ordering. Confirm the operating temperature range matches the industrial specification of -40°C to 85°C. Ensure the 16-QFN package dimensions align with the PCB footprint requirements. Check for RoHS compliance status as per the manufacturer's current documentation. Validate that the serial interface timing meets the host controller's specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 1 MHz throughput are required in a compact form factor. Consider the dual supply voltage requirements for analog and digital sections during power budgeting. Evaluate the need for differential versus single-ended inputs based on the noise environment of the application. Compare power consumption metrics against other SAR ADCs if extended battery life is critical.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8329 family of low-power, 16-bit ADCs from Texas Instruments. The family includes variants with different packaging options such as the SOIC-16 and QFN packages. These devices are designed for applications requiring moderate speed and high accuracy in a small footprint. The IBRSAR variant specifically denotes the industrial temperature grade and tape-and-reel packaging format.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS8329IBRSAT, which shares identical electrical characteristics but differs in packaging quantity or type. Verify pin compatibility and software register settings when migrating between variants. Cross-reference with other 16-bit SAR ADCs only if pinout and interface differences can be accommodated in the design.
