DAC8564IAPWR Equivalent & Substitute Parts

Part Overview

The DAC8564IAPWR is a 16-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring multi-channel voltage output conversion. This active product features four independent D/A converters in a 16-TSSOP surface mount package with buffered voltage outputs and dual interface support (SPI and DSP). The device operates across a wide supply voltage range of 2.7V to 5.5V for both analog and digital domains, making it suitable for battery-powered and industrial applications. Equivalent and substitute parts are identified based on matching electrical specifications, package compatibility, and operational parameters that ensure direct functional replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAC8564IAPWR are identified through parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following matching criteria:

Primary Matching Parameters:

• 16-bit resolution with 4 independent D/A converters
• 10µs settling time
• Buffered voltage output configuration
• SPI and DSP data interface support
• External and internal reference capability
• 2.7V to 5.5V dual supply voltage range
• ±4 LSB INL and ±0.5 LSB DNL specifications
• String DAC architecture
• -40°C to 105°C operating temperature range
• 16-TSSOP surface mount package (0.173", 4.40mm width)
• ROHS3 compliance and MSL Level 1 rating

The identified substitutes maintain identical electrical performance and package footprint, with variations limited to packaging format (Cut Tape vs. Tape & Reel) and base product number designations within the DAC8564/DAC8565 family.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status with Texas Instruments, ensuring continued availability and technical support. Each part carries ROHS3 compliance and MSL Level 1 rating, meeting environmental and reliability standards for industrial and commercial applications.

Selection between DAC8564IAPWR and DAC8564ICPWR is determined by packaging format requirements: DAC8564IAPWR is supplied in Cut Tape (CT) & Digi-Reel format, while DAC8564ICPWR is supplied in Tape & Reel (TR) format. Both variants are electrically identical and pin-compatible.

The DAC8565IAPWR and DAC8565IBPWR variants represent alternative base product numbers within the same functional family, maintaining all electrical specifications and package compatibility. DAC8565IAPWR is supplied in Cut Tape (CT) & Digi-Reel format, while DAC8565IBPWR packaging format is not specified in available data.

Component selection should be based on packaging availability, supply chain requirements, and procurement specifications rather than electrical performance, as all variants are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can DAC8564ICPWR directly replace DAC8564IAPWR in production?

A: Yes. Both parts are electrically identical with matching pin configurations, electrical specifications, and package dimensions. The difference is packaging format: DAC8564IAPWR uses Cut Tape & Digi-Reel while DAC8564ICPWR uses Tape & Reel. Selection depends on assembly equipment compatibility and procurement requirements.

Q: What is the difference between DAC8564 and DAC8565 variants?

A: Both DAC8564 and DAC8565 base product numbers maintain identical electrical specifications, resolution, converter count, settling time, supply voltage ranges, and package configuration. Substitution between these families is valid based on parametric equivalence.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts use the 16-TSSOP package with 0.173" width and 4.40mm dimensions, ensuring identical PCB footprint compatibility and surface mount assembly requirements.

Q: What packaging formats are available for these parts?

A: DAC8564IAPWR and DAC8565IAPWR are supplied in Cut Tape (CT) & Digi-Reel format. DAC8564ICPWR is supplied in Tape & Reel (TR) format. DAC8565IBPWR packaging format is not specified. Packaging selection should align with assembly line capabilities and volume requirements.

Q: Do all substitute parts meet the same environmental and compliance standards?

A: Yes. All parts are ROHS3 compliant, carry MSL Level 1 (Unlimited) moisture sensitivity rating, and maintain active product status with Texas Instruments. REACH status is unaffected for all variants.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design accommodates the specific packaging format. All electrical parameters, operating temperature ranges, supply voltage requirements, and interface specifications are identical across all substitute parts, enabling direct functional replacement.
