ADS8329IPW

Analog To Digital Converters (ADC) Overview

The ADS8329IPW is a low-power, 16-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It supports sampling rates up to 1 MSPS and features a serial interface compatible with standard SPI protocols. The device accepts single-ended or pseudo-differential unipolar input signals within a specified voltage range. It operates from a single analog supply voltage ranging from 2.7 V to 5.5 V and a separate digital I/O supply of 1.65 V to 5.5 V. Packaged in a TSSOP-16 form factor, it is designed for applications requiring high resolution and moderate speed with minimal power consumption.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 16-bit SAR ADC core with a built-in track-and-hold amplifier for accurate signal acquisition.
• Features a flexible serial interface compatible with standard SPI, Microwire, and QSPI modes.
• Supports both single-ended and pseudo-differential input configurations for versatile signal conditioning.
• Operates on a single positive analog supply while allowing independent digital logic levels.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation and battery-powered measurement devices
• Industrial process control and data acquisition systems
• Medical equipment requiring precise signal digitization

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPW confirms the TSSOP-16 package and industrial temperature grade (-40°C to +85°C). Confirm the manufacturer source is Texas Instruments or an authorized distributor, as the part originated from Burr-Brown prior to acquisition. Ensure the ordering information matches the required pinout and electrical specifications for your design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution at 1 MSPS is required with low power constraints. It is suitable for designs needing independent analog and digital supply voltages to optimize noise performance. Consider the TSSOP-16 package for surface-mount assembly. Verify that the input signal range fits the unipolar specification or requires external biasing for bipolar signals.

Analog To Digital Converters (ADC) Part Context

The ADS8329 belongs to the family of low-power, high-resolution SAR ADCs originally developed by Burr-Brown Corporation before its acquisition by Texas Instruments. This series is characterized by its ability to operate from a single supply while maintaining high accuracy. The IPW suffix specifically denotes the plastic small-outline package variant used for general-purpose electronic applications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include other 16-bit, 1 MSPS SAR ADCs from Texas Instruments such as the ADS8330 or ADS847x series, provided pin compatibility and interface requirements match. Analog Devices parts like the AD7980 may serve as functional equivalents if interface timing and supply voltages are compatible.
