DAC-08EP Equivalent & Substitute Parts

Part Overview

The DAC-08EP is an 8-bit digital-to-analog converter manufactured by Texas Instruments, housed in a 16-pin DIP package for through-hole mounting. This component functions as a multiplying DAC with current output, designed for parallel data interface applications requiring external voltage references. The DAC-08EP is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. Substitute parts maintain functional equivalence through matching electrical specifications and compatible pinouts while offering improved product status or alternative packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAC-08EP are qualified based on the following critical parameters that determine functional equivalence:

• Resolution and Converter Count: All substitutes maintain 8-bit resolution with 1 D/A converter
• Output Characteristics: Current output type, unbuffered configuration, and differential output capability remain constant
• Data Interface and Reference: Parallel data interface with external reference requirement is preserved across all substitutes
• Electrical Performance: Settling time of 150µs and multiplying DAC architecture are maintained
• Supply Voltage: Analog supply range of ±4.5V ~ 18V is consistent across all parts
• Compliance: All substitutes maintain ROHS3 compliance and REACH unaffected status

Substitutes are differentiated by package type (DIP vs. SOIC), mounting method (through-hole vs. surface mount), manufacturer (Texas Instruments vs. Analog Devices Inc.), and product status (active vs. obsolete).

Engineering Selection Recommendations

For Through-Hole Applications (Direct Pin-Compatible Replacement):

DAC08CPZ and DAC08EPZ are direct substitutes for the DAC-08EP, maintaining identical 16-DIP package geometry and through-hole mounting. Both parts are active products with current manufacturing support. DAC08EPZ matches the operating temperature range of the original part (0°C ~ 70°C), while DAC08CPZ extends the operating range to -40°C ~ 85°C, suitable for industrial applications requiring wider temperature tolerance. Both Analog Devices parts support digital supply voltage of 9V ~ 36V, providing additional design flexibility compared to the original specification.

For Surface-Mount Applications (Package Conversion):

DAC0800LCM/NOPB provides functional equivalence in a 16-SOIC surface-mount package, enabling board redesign for modern manufacturing processes. This Texas Instruments part maintains active product status and identical electrical specifications to the original DAC-08EP. Surface-mount conversion requires PCB layout modification and is appropriate for new production designs or board revisions.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component. Active product status for all three substitutes ensures long-term availability and manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: Can DAC0800LCM/NOPB replace DAC-08EP in existing through-hole designs?

A: No. DAC0800LCM/NOPB uses a 16-SOIC surface-mount package, incompatible with through-hole PCB layouts. This substitute requires board redesign and is suitable only for new surface-mount implementations.

Q: Are DAC08CPZ and DAC08EPZ pin-compatible with DAC-08EP?

A: Yes. Both parts use identical 16-DIP package geometry with matching pinout, enabling direct socket replacement in through-hole applications without PCB modification.

Q: What is the difference between DAC08CPZ and DAC08EPZ?

A: The primary difference is operating temperature range. DAC08CPZ operates from -40°C to 85°C, suitable for extended industrial temperature environments. DAC08EPZ operates from 0°C to 70°C, matching the original DAC-08EP specification. Both parts are functionally equivalent in all other electrical parameters.

Q: Do all substitutes support the same supply voltage as the original DAC-08EP?

A: All substitutes support the analog supply range of ±4.5V ~ 18V. Analog Devices parts (DAC08CPZ and DAC08EPZ) additionally specify digital supply voltage of 9V ~ 36V, providing expanded design flexibility not documented for the original part.

Q: Why is the DAC-08EP classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. Active substitute parts ensure continued availability and manufacturing support for new designs and production requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with environmental and hazardous substance restrictions.
