Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number including the G4 suffix to ensure lead-free compliance and RoHS adherence. Confirm the IPWR package variant matches the required PCB footprint. Check the manufacturer's lifecycle status to confirm availability for new designs. Ensure the operating temperature range meets the specific application environment requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 12-bit resolution and 200 kSPS speed are sufficient for the application. Choose this part over higher-resolution models if power consumption and cost are primary constraints. Verify that the serial interface timing aligns with the host microcontroller capabilities. Consider the 10-V input tolerance as a key differentiator for direct sensor interfacing.

Analog To Digital Converters (ADC) Part Context

This device belongs to the TLC257x family of serial analog-to-digital converters from Texas Instruments. It shares architectural similarities with the TLC2574 but offers reduced channel count and resolution. The family is designed for cost-sensitive applications requiring moderate performance. The IPWRG4 designation indicates a specific tape-and-reel packaging configuration for automated assembly.

Analog To Digital Converters (ADC) Replacement Considerations

The TLC2574IDWRG4 serves as a compatible alternative offering 14-bit resolution and eight channels. The TLC3544 provides similar functionality with pseudodifferential inputs. Verify pin compatibility and software driver adjustments when substituting these devices.
