ADC0848CCV Equivalent & Substitute Parts

Part Overview

The ADC0848CCV is an 8-bit Analog to Digital Converter manufactured by Texas Instruments, designed for data acquisition applications requiring parallel interface communication. This component features a Successive Approximation Register (SAR) architecture with configurable input modes (Differential, Pseudo-Differential, Single Ended) and supports 4 or 8 input channels through multiplexed configuration.

The ADC0848CCV is classified as Obsolete, making it necessary to identify equivalent substitute parts for ongoing production and maintenance applications. The primary substitute maintains identical electrical and mechanical specifications while offering improved compliance status and availability.

Engineering Selection Recommendations

The ADC0848CCV/NOPB is the direct substitute for the obsolete ADC0848CCV. Both components are functionally identical across all electrical and mechanical parameters. The primary distinction is product lifecycle status and regulatory compliance:

The original ADC0848CCV carries Obsolete status with RoHS non-compliant classification. The ADC0848CCV/NOPB maintains Last Time Buy status and achieves ROHS3 Compliant certification, making it suitable for applications requiring modern regulatory adherence. Both components share identical REACH Unaffected and EAR99 export classification status.

For new designs or production continuation, the ADC0848CCV/NOPB is the appropriate selection. Existing inventory of the original ADC0848CCV remains functionally compatible for applications without RoHS compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can ADC0848CCV/NOPB be used as a direct replacement for ADC0848CCV?

A: Yes. Both components are electrically and mechanically identical. They share the same 8-bit resolution, 25k SPS sampling rate, input channel configuration, parallel data interface, SAR architecture, supply voltage requirements, operating temperature range, and 28-PLCC surface mount package. The substitute differs only in product status and RoHS compliance.

Q: What is the significance of the /NOPB suffix?

A: The /NOPB designation indicates lead-free (no lead) packaging, which aligns with RoHS3 compliance requirements. This reflects the component's manufacturing process and environmental compliance status.

Q: Are there any package compatibility concerns when substituting?

A: No. Both the ADC0848CCV and ADC0848CCV/NOPB use identical 28-PLCC (11.51x11.51) surface mount packaging with J-Lead configuration. PCB footprints and mounting procedures remain unchanged.

Q: What is the difference between the Obsolete and Last Time Buy product statuses?

A: Obsolete status indicates the component is no longer manufactured or supported. Last Time Buy status indicates limited availability with a defined final purchase opportunity before discontinuation. The ADC0848CCV/NOPB provides a transition path for applications requiring continued supply.

Q: Are the supply voltage specifications identical?

A: Yes. Both components require 4.5V to 6V for analog supply and 4.5V to 6V for digital supply. Operating temperature range is identical at -40°C to 85°C.

Q: Does the moisture sensitivity level change between the two parts?

A: No. Both components maintain 2A moisture sensitivity level (4 Weeks), requiring identical handling and storage protocols.
