ADS8329IBRSATG4

Analog To Digital Converters (ADC) Overview

The ADS8329IBRSATG4 is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single differential or single-ended input channel and operates with an external reference voltage. The device supports a sampling rate of 1 MSPS and utilizes a serial peripheral interface (SPI) for data communication. It functions within an analog supply voltage range of 5V and a digital supply voltage range of 1.65V to 5.5V. The component is housed in a 16-VQFN package with dimensions of 4x4 mm and includes a bare pad for thermal management. It is rated for operation across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed 16-bit SAR ADC architecture for precise signal conversion.
• Supports flexible input configurations including both differential and single-ended modes.
• Features a low-power design compatible with standard SPI digital interfaces.

Analog To Digital Converters (ADC) Applications

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance when sourcing. Confirm the package type matches the 16-QFN specification for PCB layout compatibility. Ensure the supplier provides official datasheets to validate the 1.65V to 5.5V digital supply range and 1 MSPS performance characteristics before integration into the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution is required alongside a 1 MSPS sampling rate. It is suitable for designs needing a single-channel input with flexible reference options. Consider the 16-VQFN package constraints for thermal dissipation and board space. Verify that the system can accommodate the specified analog and digital supply voltage ranges.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS8329 family of 16-bit SAR ADCs from Texas Instruments. The base model ADS8329 offers similar electrical specifications, while the IBRSATG4 variant specifies the industrial temperature grade, RoHS-compliant packaging, and tape-and-reel delivery format. It serves as a precision data conversion solution within the broader TI analog signal chain portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other 16-bit SAR ADCs from Texas Instruments such as the ADS8330 or ADS8344, provided pinout and interface compatibility are verified. Cross-vendor replacements require careful evaluation of sampling rates, input types, and supply voltage requirements to ensure functional equivalence.
