DAC7632VFBR Equivalent & Substitute Parts

Part Overview

The DAC7632VFBR is a 16-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring dual voltage output channels. This device features SPI interface compatibility, external reference capability, and operates across industrial temperature ranges. The DAC7632VFBR is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DAC7632VFBR is determined by strict parametric matching across core electrical and mechanical specifications. All substitute parts must maintain identical values for the following critical parameters:

• Number of bits: 16
• Number of D/A converters: 2
• Settling time: 10µs
• Output type: Voltage - Buffered
• Data interface: SPI
• Reference type: External
• Analog supply voltage: ±5V
• Digital supply voltage: 5V
• Architecture: R-2R
• Operating temperature range: -40°C ~ 85°C
• Package type: 32-LQFP (7x7)
• Mounting type: Surface Mount

The identified substitute parts DAC7632VFBT and DAC7632VFR meet these parametric requirements. Differences in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and product status (Active versus Obsolete) do not affect functional equivalence. Minor variations in INL/DNL specifications are within acceptable tolerance ranges for this device category.

Parameter Comparison

Engineering Selection Recommendations

Both DAC7632VFBT and DAC7632VFR are functionally equivalent to the obsolete DAC7632VFBR across all critical electrical and mechanical parameters. Selection between these two active alternatives should be based on supply chain availability and packaging requirements.

DAC7632VFBT is supplied in Tape & Reel format, suitable for high-volume automated assembly operations. DAC7632VFR is supplied in Cut Tape & Digi-Reel format, offering flexibility for lower-volume or mixed-component procurement scenarios. Both parts maintain identical ROHS3 compliance, MSL ratings, and REACH status as the original part.

The DAC7632VFR exhibits slightly relaxed INL/DNL specifications (±3, ±2 LSB versus ±2, ±1 LSB), which remains within acceptable tolerance for most data acquisition applications but should be evaluated against specific system accuracy requirements.

Frequently Asked Questions (FAQ)

Q: Can DAC7632VFBT and DAC7632VFR be used interchangeably with DAC7632VFBR?

A: Yes. Both substitute parts maintain identical electrical performance parameters, package geometry, pin configuration, and operating characteristics. The primary differences are product status (active versus obsolete) and packaging format.

Q: What is the significance of the packaging format difference between Tape & Reel and Cut Tape & Digi-Reel?

A: Packaging format affects procurement and assembly logistics. Tape & Reel packaging is optimized for automated pick-and-place assembly in high-volume production. Cut Tape & Digi-Reel format provides flexibility for manual assembly, prototyping, or mixed-component orders. Electrical and mechanical performance is identical.

Q: Does the INL/DNL specification difference between DAC7632VFR and the other parts affect substitution?

A: The DAC7632VFR exhibits INL/DNL of ±3, ±2 LSB compared to ±2, ±1 LSB for DAC7632VFBR and DAC7632VFBT. This represents a relaxation of linearity specifications. Substitution is valid if system accuracy requirements accommodate this tolerance range.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. DAC7632VFBR, DAC7632VFBT, and DAC7632VFR are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the moisture sensitivity level, and does it affect handling?

A: All three parts carry MSL 3 rating with a 168-hour floor life. This indicates standard moisture sensitivity requiring standard ESD and moisture control procedures during storage and assembly. No special handling beyond industry-standard practices is required.
