ADC0848BCV Equivalent & Substitute Parts

Part Overview

The ADC0848BCV is an 8-bit Successive Approximation Register (SAR) analog-to-digital converter manufactured by Texas Instruments, housed in a 28-PLCC surface mount package. This device supports 4 or 8 differential, pseudo-differential, or single-ended analog inputs with a 25 kHz sampling rate and parallel data interface. The ADC0848BCV is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support, design updates, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADC0848BCV is determined by strict equivalence across the following critical parameters:

• Resolution: 8-bit conversion capability
• Sampling Rate: 25 kHz per second
• Input Configuration: Support for 4 or 8 channels with differential, pseudo-differential, and single-ended input modes
• Data Interface: Parallel output protocol
• Architecture: SAR-based conversion
• Reference Input: External reference requirement
• Supply Voltage: Dual supply rails operating at 4.5V to 6V for both analog and digital domains
• Operating Temperature Range: -40°C to 85°C
• Package Compatibility: 28-PLCC (11.51x11.51) surface mount footprint

The ADC0848CCV/NOPB qualifies as a parametric equivalent substitute, maintaining identical electrical specifications and mechanical compatibility while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The ADC0848CCV/NOPB is the direct parametric equivalent for the obsolete ADC0848BCV. Both devices share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility in existing circuit designs.

The ADC0848CCV/NOPB offers two significant advantages over the original part:

• Product Status: Classified as Last Time Buy, providing extended availability compared to the Obsolete status of the ADC0848BCV
• Regulatory Compliance: ROHS3 compliant, meeting current environmental and hazardous substance restrictions, whereas the ADC0848BCV is RoHS non-compliant

For new designs or system updates requiring compliance with modern regulatory standards, the ADC0848CCV/NOPB is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either part maintains functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the ADC0848CCV/NOPB be used as a direct replacement for the ADC0848BCV?

A: Yes. Both devices are electrically and mechanically identical across all specified parameters, including resolution, sampling rate, input configuration, supply voltage, operating temperature range, and 28-PLCC package footprint. No circuit modifications are required.

Q: What is the difference between the ADC0848BCV and ADC0848CCV/NOPB?

A: The primary differences are product status and regulatory compliance. The ADC0848BCV is obsolete and RoHS non-compliant, while the ADC0848CCV/NOPB is Last Time Buy and ROHS3 compliant. All electrical and mechanical specifications remain identical.

Q: Are there any packaging differences between these parts?

A: Both parts use the 28-PLCC (11.51x11.51) surface mount package with J-Lead configuration. The ADC0848CCV/NOPB is supplied in Tube packaging, while the ADC0848BCV packaging specification is not detailed. This does not affect electrical or mechanical compatibility.

Q: What is the moisture sensitivity level difference, and does it affect substitution?

A: The ADC0848BCV has MSL 1 (Unlimited), while the ADC0848CCV/NOPB has MSL 2A (4 Weeks). This affects storage and handling procedures but does not impact electrical performance or functional compatibility. MSL 2A requires controlled humidity storage and has a 4-week floor life after moisture exposure.

Q: Can the ADC0848CCV/NOPB be used in applications requiring RoHS non-compliance?

A: Yes. The ADC0848CCV/NOPB is ROHS3 compliant and can be used in any application, including those not requiring RoHS compliance. Compliance is a superset of non-compliance requirements.
