ADC0848CCN Equivalent & Substitute Parts

Part Overview

The ADC0848CCN is an 8-bit Analog to Digital Converter manufactured by Texas Instruments, configured as a SAR (Successive Approximation Register) architecture device with 4 or 8 differential, pseudo-differential, or single-ended inputs. The device operates with external voltage references and parallel data interface, housed in a 24-DIP through-hole package. The ADC0848CCN is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADC0848CCN is determined by the following critical parameters:

• Resolution: 8-bit conversion capability
• Sampling Rate: Minimum 25 kSPS to maintain or exceed original performance
• Number of Inputs: 8-input configuration to support full channel capacity
• Input Type: Single-ended input support (minimum requirement)
• Architecture: SAR-based conversion
• Reference Type: Supply or external reference capability
• Supply Voltage Range: Compatibility with 2.7V to 5.25V operating envelope
• Operating Temperature: Extended range support (-40°C to 105°C preferred for active components)
• Product Status: Active status required for production use

The ADC088S022CIMT/NOPB meets these substitution criteria as an active, RoHS-compliant alternative with enhanced specifications.

Engineering Selection Recommendations

The ADC088S022CIMT/NOPB is the manufacturer-recommended substitute for the ADC0848CCN. Selection of this alternative is justified by the following factors:

• Product Status: The ADC0848CCN is obsolete; the ADC088S022CIMT/NOPB is active and supported by Texas Instruments.
• Regulatory Compliance: The ADC088S022CIMT/NOPB is ROHS3 compliant, meeting current environmental and regulatory requirements, whereas the ADC0848CCN is RoHS non-compliant.
• Functional Compatibility: Both devices share 8-bit resolution and SAR architecture. The substitute provides 8x higher sampling rate (200 kSPS vs. 25 kSPS), supporting higher-speed applications.
• Supply Voltage: The ADC088S022CIMT/NOPB operates across a wider voltage range (2.7V ~ 5.25V), providing greater design flexibility.
• Operating Temperature: The substitute supports extended temperature range (-40°C ~ 105°C), suitable for industrial and automotive applications.

Design modifications required: Interface protocol change from parallel to SPI/DSP; package change from through-hole DIP to surface-mount TSSOP; external reference circuit may be eliminated due to supply reference capability.

Frequently Asked Questions (FAQ)

Q: Can the ADC088S022CIMT/NOPB directly replace the ADC0848CCN without circuit modifications?

A: No. While both are 8-bit SAR ADCs, the data interface differs fundamentally. The ADC0848CCN uses parallel output; the ADC088S022CIMT/NOPB uses SPI/DSP serial interface. Microcontroller firmware and PCB layout modifications are required.

Q: What is the impact of changing from 24-DIP to 16-TSSOP packaging?

A: The ADC088S022CIMT/NOPB requires surface-mount assembly instead of through-hole insertion. PCB design, assembly process, and test procedures must be updated accordingly. The smaller footprint reduces board space requirements.

Q: Is the ADC088S022CIMT/NOPB compatible with 5V-only systems?

A: Yes. The ADC088S022CIMT/NOPB operates within the 2.7V ~ 5.25V range, which includes 5V systems. However, systems requiring 4.5V ~ 6V operation (above 5.25V) require voltage regulation.

Q: Why does the ADC088S022CIMT/NOPB use supply reference instead of external reference?

A: Supply reference simplifies circuit design by eliminating external reference components. External reference capability can be implemented through firmware configuration if required for specific applications.

Q: What are the implications of the 8x sampling rate increase?

A: The ADC088S022CIMT/NOPB's 200 kSPS rate supports higher-frequency signal acquisition. Applications limited by the original 25 kSPS rate can now capture faster transients. Nyquist frequency considerations and anti-aliasing filter design may require adjustment.

Q: Is the ADC088S022CIMT/NOPB suitable for differential input applications?

A: The ADC088S022CIMT/NOPB supports single-ended inputs only. Differential signal conditioning must be implemented externally if differential measurements are required.
