Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPWR corresponds to the 16-TSSOP package and tape-and-reel packaging format. Confirm RoHS compliance status matches current manufacturing standards. Check for any recent Product Change Notifications regarding marking changes or material substitutions that may affect long-term sourcing stability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 16-bit resolution with 1kSPS speed is sufficient for the application. Ensure the I2C interface compatibility exists with the host microcontroller. Verify that the 2.3V to 5.5V supply range aligns with the system power design. Consider the 16-TSSOP footprint constraints during PCB layout planning.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS111x family of precision ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS1115 but offers distinct channel counts and interface options. The IPWR designation specifically identifies the industrial-grade temperature range and surface-mount TSSOP packaging variant within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include ADS1119IDR for SOIC-16 packaging. For pin-compatible alternatives with different interfaces, consider ADS1115 variants. Verify electrical parameters match exactly before substitution, particularly regarding supply voltage ranges and I2C address configurations.
