DDC101UG4

Analog To Digital Converters (ADC) Overview

The DDC101UG4 is a 20-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes an adaptive delta-sigma architecture and features a single-ended input configuration. The device operates on a 5V supply for both analog and digital domains, supporting a sampling rate of 15 kSPS. Data is transferred via an SPI interface. It is housed in a 24-SOIC package with a width of 7.50 mm and functions within a temperature range of -40°C to 85°C.

Analog To Digital Converters (ADC) Feature Summary

• Adaptive delta-sigma architecture for high-resolution signal conversion
• Single-ended input capability for charge integration applications
• SPI digital interface for data output and control

Analog To Digital Converters (ADC) Applications

• Precision sensor signal conditioning
• Low-frequency measurement systems
• Industrial instrumentation requiring high resolution

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance against current RoHS standards. Confirm the 24-SOIC package dimensions match the design footprint. Ensure the 5V supply requirement aligns with system power rails. Check for any obsolescence notices or lifecycle changes from the manufacturer before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 20-bit resolution is required for low-speed applications. The 15 kSPS sampling rate suits slow-varying signals. Verify that the single-ended input topology fits the source impedance constraints. Consider the 24-SOIC package size for PCB layout limitations compared to smaller alternatives.

Analog To Digital Converters (ADC) Part Context

This part belongs to the DDC101 family of precision ADCs. It serves as a lead-free compliant variant of the standard DDC101 model. The device is designed for applications demanding high accuracy in low-bandwidth scenarios, distinguishing it from higher-speed data converters in the broader portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

The DDC101U is the direct non-lead-free equivalent. The DDC112UKG4 offers dual-channel functionality with similar resolution but requires different pinout consideration.
