ADS8329IPWR

Analog To Digital Converters (ADC) Overview

The ADS8329IPWR 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 unipolar input architecture with an internal 2.5V reference and a high-speed serial interface compatible with standard SPI modes. The device supports sampling rates up to 1 MHz while maintaining low power consumption, making it suitable for battery-operated systems. It operates from a single supply voltage ranging from 2.7V to 5.5V and is housed in a TSSOP-16 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPWR indicates the TSSOP-16 package and industrial temperature grade. Confirm the revision level matches the design requirements, as older Burr-Brown datasheets may list variations. Ensure the serial interface timing aligns with the host microcontroller's SPI configuration before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution and 1 MHz sampling rate are required in a compact surface-mount package. It is appropriate for designs needing a single-supply operation between 2.7V and 5.5V. Consider the internal reference stability and input range constraints compared to external reference solutions if higher precision is needed.

Analog To Digital Converters (ADC) Part Context

The ADS8329 belongs to the broader family of low-power SAR ADCs originally developed by Burr-Brown, which was acquired by Texas Instruments. This series is designed to bridge the gap between high-speed converters and ultra-low-power devices, offering a balance of performance and energy efficiency for embedded sensing applications.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible upgrades within the ADS8xxx series. Verify that any substitute maintains the 16-bit resolution and 1 MHz speed. Ensure the new part supports the same unipolar input range and serial protocol compatibility.
