DDC112YK/250

Analog To Digital Converters (ADC) Overview

The DDC112YK/250 is a dual-channel, 20-bit analog-to-digital converter (ADC) from Texas Instruments, utilizing sigma-delta architecture. It features two single-ended current inputs and communicates via an SPI interface. The device operates on a 5V supply with a sampling rate of 3kS/s. Packaged in a 32-TQFP (7x7 mm) surface-mount format, it supports external reference types and includes synchronous sampling capabilities. The component is designed for precision data acquisition applications requiring high resolution.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'YK' against official Texas Instruments documentation to confirm package type and temperature range specifications. Ensure compatibility with the DDC11XEVM-PDK development kit if evaluation is required. Confirm moisture sensitivity level handling procedures during storage and assembly to prevent damage.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel current sensing with high resolution is required. Compare against other DDC112 variants based on packaging requirements, such as TQFP versus SOIC, and thermal performance needs. Verify that the 3kS/s sampling rate meets system bandwidth requirements and that SPI interface compatibility exists with the host microcontroller.

Analog To Digital Converters (ADC) Part Context

This part belongs to the DDC112 series of dual current input ADCs. It shares core architectural similarities with variants like the DDC112Y and DDC112U but differs in packaging and potentially environmental ratings. The series is specifically engineered for medical imaging and industrial sensor applications demanding high accuracy.

Analog To Digital Converters (ADC) Replacement Considerations

Consider the DDC112Y or DDC112U for functional equivalents with different packaging options. Verify pinout compatibility and electrical specifications before substitution. No direct cross-manufacturer replacements are documented in public sources.
