DDC118IRTCT

Analog To Digital Converters (ADC) Overview

The DDC118IRTCT is a quad current input analog-to-digital converter manufactured by Texas Instruments. It features a 20-bit resolution and utilizes sigma-delta architecture to achieve high precision measurements. The device integrates four dedicated current-input channels, eliminating the need for external shunt resistors in many applications. It operates with an analog supply voltage range of 4.75 V to 5.25 V and supports digital interfaces compatible with standard serial protocols. The component is housed in a 38-pin NFBGA package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRTCT against the manufacturer's latest datasheet to confirm pinout compatibility and package dimensions. Ensure that the procurement source provides original manufacturer documentation to validate authenticity. Cross-reference the part number with official distributors to confirm availability status and lead times before finalizing orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when multiple low-level current signals require simultaneous digitization without external signal conditioning. Compare channel count and resolution requirements against alternative ADCs. Verify that the system power supply constraints align with the specified 5V analog and digital voltage ranges for optimal performance.

Analog To Digital Converters (ADC) Part Context

This device belongs to the DDC11x family of current-input ADCs from Texas Instruments. It serves as the octal-channel variant within this series, offering higher channel density compared to dual or quad-channel counterparts. The family is designed specifically for applications demanding high-resolution conversion of current-based sensor outputs.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other members of the DDC11x family such as the DDC114 or DDC112, depending on required channel count. Alternative devices must match the 20-bit resolution and current-input architecture. Verify pin compatibility and software register configurations when migrating between different channel counts within the same product line.
