ADS7229IRSATG4

Analog To Digital Converters (ADC) Overview

The ADS7229IRSATG4 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single pseudo-differential or single-ended input channel and operates with an external reference voltage. The device supports sampling rates up to 1 MSPS and utilizes a standard SPI or DSP-compatible digital interface for data transfer. It functions within an analog supply range of 2.7V to 5.5V and a digital supply range of 1.65V to 5.5V. The component is housed in a 16-pin QFN package measuring 4x4 mm, suitable for surface-mount assembly across industrial temperatures from -40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS3 status when sourcing. Confirm the package type matches the 16-QFN (4x4mm) specification required for your PCB footprint. Ensure the operating temperature range meets your environmental requirements. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between speed and resolution is required for single-channel applications. Consider the external reference requirement if system accuracy demands high precision. Evaluate the power supply constraints to ensure both analog and digital rails fall within the specified ranges. Compare against higher-resolution alternatives if greater accuracy is needed for the target application.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7229 family of low-power, 12-bit ADCs. The 'G4' suffix typically denotes a lead-free and RoHS-compliant variant of the standard ADS7229IRSAT. It serves as a cost-effective solution for applications needing fast conversion times without the complexity of multi-channel architectures found in other TI series.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include the ADS7229IRSR and ADS7229IRSGR, which share identical electrical specifications but differ in package types. Verify that any replacement maintains the same 16-pin QFN footprint or adapts accordingly to the design.
