DAC7725UG4 Equivalent & Substitute Parts

Part Overview

The DAC7725UG4 is a 12-bit quad digital-to-analog converter manufactured by Texas Instruments, housed in a 28-SOIC surface mount package. This device provides four independent voltage output channels with buffered outputs, external reference capability, and parallel data interface. The product is currently discontinued at DiGi Electronics, necessitating identification of equivalent alternatives for ongoing system support and new designs requiring this functional specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DAC7725UG4 is determined by strict equivalence across all critical electrical and mechanical parameters. The following criteria establish valid substitutes:

• 12-bit resolution with 4 independent D/A converters
• Buffered voltage output configuration
• Parallel data interface with external reference capability
• Identical settling time of 10µs
• Matching supply voltage ranges: ±14.25V ~ 15.75V (analog) and 5V (digital)
• Equivalent INL/DNL specifications: ±2 LSB maximum / ±1 LSB maximum
• R-2R architecture
• Operating temperature range of -40°C ~ 85°C
• 28-SOIC surface mount package with identical physical dimensions

Two parts meet these criteria: DAC7725U (Burr Brown) and DAC7724U (Texas Instruments).

Parameter Comparison

Engineering Selection Recommendations

Both DAC7725U and DAC7724U are parametrically equivalent to the discontinued DAC7725UG4 across all specified electrical and mechanical characteristics. Selection between these substitutes should be based on the following factors:

DAC7725U (Burr Brown) is available in bulk packaging with 1403 units in stock and maintains active product status.

DAC7724U (Texas Instruments) is available in tube packaging with 1483 units in stock, maintains active product status, and carries ROHS3 compliance certification matching the original part.

For applications requiring documented RoHS3 compliance, DAC7724U provides direct compliance alignment with the original DAC7725UG4 specification. Both parts are electrically and mechanically interchangeable within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can DAC7725U and DAC7724U be used interchangeably with DAC7725UG4?

A: Yes. Both substitute parts match all critical electrical parameters (resolution, settling time, supply voltages, INL/DNL specifications, architecture) and are housed in identical 28-SOIC packages with matching pin configurations and physical dimensions.

Q: What is the primary difference between the two substitute options?

A: DAC7725U is manufactured by Burr Brown and supplied in bulk packaging. DAC7724U is manufactured by Texas Instruments and supplied in tube packaging. DAC7724U carries explicit ROHS3 compliance certification. Both are electrically equivalent.

Q: Are there any packaging considerations for PCB assembly?

A: Both substitutes use the same 28-SOIC surface mount package as the original DAC7725UG4. No PCB layout modifications are required. Packaging format (bulk vs. tube) affects component handling and storage but not electrical performance or board integration.

Q: Why is the original DAC7725UG4 discontinued?

A: Product discontinuation information is not provided in the technical specification. Contact the manufacturer or authorized distributor for lifecycle details.

Q: Do the substitute parts require any design modifications?

A: No design modifications are required. The substitute parts are parametrically equivalent across all specified electrical and mechanical parameters, including supply voltages, signal timing, package dimensions, and pin configuration.
