DAC8565IBPWR Equivalent & Substitute Parts

Part Overview

The DAC8565IBPWR is a 16-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring four independent voltage output channels. This active product features buffered voltage outputs, supports both SPI and DSP data interfaces, and operates across a wide supply voltage range of 2.7V to 5.5V for both analog and digital supplies. The component is housed in a 16-TSSOP surface mount package and maintains ROHS3 compliance with unlimited moisture sensitivity rating.

Substitute parts are identified when design requirements necessitate alternative packaging formats, inventory availability considerations, or equivalent performance specifications across the DAC8564 and DAC8565 product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAC8565IBPWR are identified based on strict parametric equivalence across the following criteria:

Core Electrical Parameters (Must Match):

• 16-bit resolution with 4 independent D/A converters
• Buffered voltage output configuration
• SPI and DSP data interface support
• External and internal reference capability
• 2.7V to 5.5V supply voltage range (analog and digital)
• 10µs settling time
• ±4 LSB INL and ±0.5 LSB DNL specifications
• String DAC architecture
• -40°C to 105°C operating temperature range

Mechanical Parameters (Must Match):

• 16-TSSOP package with 0.173" width (4.40mm)
• Surface mount mounting type

Compliance Parameters (Must Match):

• ROHS3 compliance
• MSL Level 1 (Unlimited)
• REACH Unaffected status

The substitute parts differ only in packaging format (Cut Tape & Digi-Reel® or Tape & Reel) and base product number designation (DAC8564 vs. DAC8565 series), while maintaining identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status with Texas Instruments and satisfy identical electrical and mechanical specifications. Selection between DAC8565IBPWR and its substitutes is determined by packaging and supply chain requirements rather than functional performance.

DAC8564IAPWR and DAC8565IAPWR are available in Cut Tape & Digi-Reel® packaging, suitable for applications requiring flexible order quantities and handling methods. DAC8564ICPWR is supplied in Tape & Reel format, optimized for high-volume automated assembly processes. All parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can DAC8564IAPWR replace DAC8565IBPWR in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical specifications, operating temperature range, supply voltage requirements, and mechanical package dimensions. The difference lies in packaging format. DAC8564IAPWR uses Cut Tape & Digi-Reel® packaging while DAC8565IBPWR is supplied in bulk format.

Q: What is the difference between DAC8564 and DAC8565 series designations?

A: The series designation does not indicate functional differences in electrical performance. Both DAC8564 and DAC8565 variants maintain identical 16-bit resolution, 4-channel configuration, buffered voltage output, and all specified electrical parameters. The designation reflects internal product line organization within Texas Instruments.

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

A: Yes. All substitute parts use the 16-TSSOP package with identical 0.173" width (4.40mm) and surface mount configuration. PCB layout and footprint design remain unchanged across all listed substitutes.

Q: Do packaging format differences affect component performance?

A: No. Cut Tape & Digi-Reel® and Tape & Reel packaging formats are supply and handling methods only. Electrical performance, settling time, linearity specifications, and operating characteristics are identical across all packaging options.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. DAC8564IAPWR, DAC8564ICPWR, and DAC8565IAPWR all maintain ROHS3 compliance with MSL Level 1 (Unlimited) rating and REACH Unaffected status, matching the compliance profile of DAC8565IBPWR.

Q: Which substitute should be selected for high-volume production?

A: DAC8564ICPWR in Tape & Reel format is optimized for automated assembly processes typical of high-volume manufacturing. DAC8564IAPWR and DAC8565IAPWR in Cut Tape & Digi-Reel® format provide flexibility for lower-volume or mixed-quantity requirements.
