DDC232CGXGR-2

Analog To Digital Converters (ADC) Overview

The DDC232CGXGR-2 is a 32-channel, current-input analog-to-digital converter manufactured by Texas Instruments. It utilizes sigma-delta architecture with 20-bit resolution and a sample rate of 6 kSPS per channel. The device features an external reference input and supports single-ended inputs. It operates on a 5V analog supply and a digital supply ranging from 2.7V to 5.25V. Communication is handled via an SPI interface. The component is housed in a 64-NFBGA (8x8) package and is rated for operation between 0°C and 70°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '-2' against official Texas Instruments documentation to confirm if it denotes a distinct revision or packaging variant. Confirm current product status as the base DDC232 model may be discontinued. Ensure compatibility with existing board layouts for the 64-NFBGA package before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component for systems requiring high-resolution digitization of low-level current signals across multiple channels. Verify that the required sampling rate of 6 kSPS meets system timing constraints. Ensure the design accommodates the need for an external voltage reference and the specific power supply requirements for analog and digital sections.

Analog To Digital Converters (ADC) Part Context

The DDC232 belongs to Texas Instruments' family of current-input data converters, designed specifically for integrating charge-based sensors. It serves as a high-channel-count solution compared to octal or quad-channel counterparts like the DDC118 or DDC112. The NFBGA package allows for compact PCB implementation in dense electronic assemblies.
