DAC7614UBG4 Equivalent & Substitute Parts

Part Overview

The DAC7614UBG4 is a 12-bit digital-to-analog converter featuring four independent channels with serial input interface, designed for applications requiring buffered voltage output. Manufactured by Texas Instruments in a 16-SOIC surface mount package, this component operates across the industrial temperature range of -40°C to 85°C. The product is currently discontinued at DiGi Electronics, necessitating identification of equivalent alternatives that maintain full electrical and mechanical compatibility for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC7614UBG4 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish the substitution criteria:

• 12-bit resolution with 4 independent D/A converter channels
• 10µs settling time performance
• Buffered voltage output configuration
• SPI serial data interface
• External reference input requirement
• ±5V analog and 5V digital supply voltages
• ±1 LSB maximum INL/DNL specifications
• R-2R resistor ladder architecture
• Industrial temperature range (-40°C to 85°C)
• 16-SOIC surface mount package with 0.295" width
• ROHS3 compliance and MSL 3 rating

Substitute parts must match all parameters listed above without exception. Manufacturer differences do not affect substitution validity when all electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

Both DAC7614UB and DAC7615UB provide complete electrical and mechanical equivalence to the DAC7614UBG4. Selection between these substitutes is based on product availability and compliance documentation requirements.

DAC7614UB, manufactured by Burr Brown, maintains active product status and offers immediate availability. This part satisfies all electrical specifications and package requirements for direct substitution.

DAC7615UB, manufactured by Texas Instruments, provides continuity with the original manufacturer while maintaining active product status. This part includes documented ROHS3 compliance and MSL 3 rating, matching the original part's environmental specifications. Packaging is specified as Tube format.

Both substitutes are suitable for applications requiring the DAC7614UBG4 specifications. Selection should prioritize product availability, supply chain lead times, and packaging format requirements for the specific application.

Frequently Asked Questions (FAQ)

Q: Can DAC7614UB and DAC7615UB be used interchangeably with DAC7614UBG4?

A: Yes. Both parts match all critical electrical parameters (12-bit resolution, 4 channels, 10µs settling time, SPI interface, ±5V/5V supply, ±1 LSB INL/DNL) and mechanical specifications (16-SOIC package, surface mount, industrial temperature range). Pinout and functional operation are identical.

Q: What is the difference between the substitute parts?

A: DAC7614UB is manufactured by Burr Brown, while DAC7615UB is manufactured by Texas Instruments. Both meet identical electrical specifications. DAC7615UB includes documented ROHS3 compliance and MSL 3 rating. Packaging format differs: DAC7614UB status does not specify packaging format, while DAC7615UB is supplied in Tube format.

Q: Why is the original DAC7614UBG4 discontinued?

A: Product discontinuation at DiGi Electronics indicates end-of-life status for this specific part number. Equivalent alternatives with identical specifications remain available through active product lines.

Q: Are there any compatibility concerns with PCB layout or thermal management?

A: No. Both substitute parts use the identical 16-SOIC package with 0.295" width. PCB footprints, thermal characteristics, and mounting requirements are unchanged. Existing board designs require no modification.

Q: What compliance certifications apply to each substitute?

A: DAC7615UB carries ROHS3 compliance and MSL 3 (168 Hours) rating. DAC7614UB compliance documentation is not specified in available data. Both parts carry ECCN EAR99 and HTSUS 8542.39.0001 classifications.
