DDC112Y/2K

Analog To Digital Converters (ADC) Overview

The DDC112Y/2K is a dual-channel, 20-bit analog-to-digital converter (ADC) from Texas Instruments, designed for precision current input applications. It utilizes a sigma-delta architecture and features single-ended inputs with an external reference type. The device operates on a 4.75 V to 5.25 V analog supply and a 4.75 V digital supply, communicating via an SPI interface. It supports a sampling rate of 2 kS/s and is housed in a 32-TQFP package. The component functions within a temperature range of -40°C to +85°C, with a power dissipation of 100 mW.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '2K' indicates reel packaging containing 2000 units, distinct from tape-and-reel or tube variants. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to humidity sensitivity classification. Cross-reference the datasheet revision date to validate parameter accuracy against current production standards.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel, high-resolution current sensing is required for medical imaging or scientific instrumentation. Compare against the DDC112U for SOIC-28 packaging alternatives if board space constraints differ. Evaluate the DDC112YK/250 variant if different packaging quantities or industrial temperature ranges are necessary for the specific application environment.
