DAC7725N Equivalent & Substitute Parts

Part Overview

The DAC7725N is a 12-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, featuring four independent voltage output channels in a 28-PLCC surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The DAC7725N operates with dual supply voltages (±14.25V to ±15.75V analog, 5V digital) and delivers 10µs settling time with R-2R architecture, suitable for precision data acquisition applications requiring buffered voltage outputs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DAC7725N is determined by strict equivalence across the following critical parameters: 12-bit resolution, four independent D/A converters, buffered voltage output configuration, 10µs settling time, parallel data interface, external reference type, R-2R architecture, 28-PLCC package footprint, surface mount mounting, and operating temperature range of -40°C to 85°C.

The identified substitute parts are grouped into two categories:

Parametric Equivalents (Same Manufacturer Family): DAC7724N and DAC7725NB maintain identical electrical specifications and package compatibility with the DAC7725N, differing only in product status (active versus obsolete) and packaging format (tube versus bulk).

Cross-Manufacturer Equivalents (Analog Devices): DAC8412FPCZ, DAC8413FPCZ, and DAC8413FPCZ-REEL are manufactured by Analog Devices Inc. and meet all core functional and mechanical requirements. These parts operate with a different analog supply voltage range (5V ~ 15V, -15V) but maintain identical resolution, channel count, settling time, output type, data interface, architecture, package, and temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer Family):

DAC7725NB is the primary recommended substitute for the obsolete DAC7725N. Both are manufactured by Burr Brown with identical electrical specifications and package compatibility. DAC7725NB carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The only distinction is packaging format: DAC7725N is supplied in tube packaging while DAC7725NB is supplied in bulk. This substitution requires no circuit modifications.

DAC7724N is a parametric equivalent offering identical performance characteristics and active product status. Selection between DAC7724N and DAC7725NB depends on packaging requirements and inventory availability.

For Cross-Manufacturer Substitution (Analog Devices):

DAC8412FPCZ, DAC8413FPCZ, and DAC8413FPCZ-REEL are functionally equivalent alternatives from Analog Devices Inc. All three maintain the same 12-bit resolution, four-channel configuration, 10µs settling time, parallel interface, and 28-PLCC package footprint. The primary electrical difference is the analog supply voltage range: Analog Devices parts accept 5V ~ 15V and -15V supplies, providing greater flexibility than the Texas Instruments specification of ±14.25V ~ 15.75V.

DAC8413FPCZ and DAC8413FPCZ-REEL are identical in electrical performance; the distinction is packaging format (tube versus tape & reel). DAC8412FPCZ is also electrically equivalent with identical specifications.

All Analog Devices substitutes carry active product status, ROHS3 compliance, and REACH unaffected designation. These parts are suitable for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can DAC7725NB be used as a direct replacement for DAC7725N without circuit modifications?

A: Yes. DAC7725NB is electrically and mechanically identical to DAC7725N. Both operate with ±14.25V ~ 15.75V analog supply and 5V digital supply, feature identical 12-bit resolution, four-channel configuration, 10µs settling time, and 28-PLCC package footprint. The only difference is packaging format (bulk versus tube). No circuit changes are required.

Q: What is the key difference between DAC7725NB and the Analog Devices substitutes (DAC8412FPCZ, DAC8413FPCZ)?

A: The primary difference is analog supply voltage range. DAC7725NB requires ±14.25V ~ 15.75V, while Analog Devices parts accept 5V ~ 15V and -15V. All other electrical parameters—resolution, channel count, settling time, output type, data interface, architecture, and operating temperature—are identical. If your system uses ±15V supplies, both families are compatible. If your system uses different supply voltages, verify compatibility with the specific part's datasheet.

Q: Are DAC8413FPCZ and DAC8413FPCZ-REEL electrically identical?

A: Yes. DAC8413FPCZ and DAC8413FPCZ-REEL are electrically identical. The difference is packaging format: DAC8413FPCZ is supplied in tube packaging, while DAC8413FPCZ-REEL is supplied in tape & reel format. Select based on your assembly process requirements and volume needs.

Q: Can I use DAC8412FPCZ instead of DAC8413FPCZ?

A: Yes. DAC8412FPCZ and DAC8413FPCZ are electrically equivalent with identical 12-bit resolution, four-channel configuration, 10µs settling time, parallel interface, and 28-PLCC package. Selection between these parts depends on availability and inventory requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. DAC7724N, DAC7725NB, DAC8412FPCZ, DAC8413FPCZ, and DAC8413FPCZ-REEL are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the operating temperature range for all these parts?

A: All substitute parts operate across the identical temperature range of -40°C to 85°C, matching the DAC7725N specification.

Q: Which substitute part has the best long-term availability?

A: DAC7725NB, DAC8412FPCZ, DAC8413FPCZ, and DAC8413FPCZ-REEL all carry active product status, ensuring ongoing availability. DAC7724N also carries active status. The obsolete DAC7725N should be replaced with one of these active alternatives for new designs and long-term system support.
