DAC8564IDPWR Equivalent & Substitute Parts

Part Overview

The DAC8564IDPWR is a 16-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, designed for data acquisition applications. This device integrates four independent 16-bit DAC channels in a 16-TSSOP surface mount package. The part is currently in active production status with full RoHS3 compliance and REACH unaffected certification. Substitute parts are identified based on matching electrical specifications, package compatibility, and manufacturing certifications to ensure direct functional equivalence in circuit design.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAC8564IDPWR are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain constant:

• 16-bit resolution with 4 independent DAC channels
• 10µs settling time performance
• Voltage-buffered 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
• 16-TSSOP package footprint (0.173" × 4.40mm width)
• Surface mount technology
• Operating temperature range of -40°C to 105°C
• RoHS3 compliance and REACH unaffected status

All identified substitute parts maintain these specifications identically. Variations in packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and base product number designations (DAC8564 versus DAC8565) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain identical electrical performance and mechanical compatibility with the DAC8564IDPWR. Selection among these parts should be based on the following factors:

Packaging Format: DAC8564IAPWR and DAC8565IAPWR are supplied in Cut Tape & Digi-Reel format, suitable for automated assembly and bulk procurement. DAC8564ICPWR is supplied in Tape & Reel format, optimized for high-volume production environments. DAC8564IDPWR and DAC8565IBPWR have unspecified packaging designations.

Inventory Availability: Current stock levels vary across substitute options. DAC8565IAPWR maintains the highest inventory at 3400 pieces, followed by DAC8564IAPWR at 2052 pieces, DAC8565IBPWR at 1593 pieces, and DAC8564ICPWR at 1079 pieces.

Compliance Certification: All parts carry identical RoHS3 compliance and REACH unaffected status, ensuring regulatory equivalence for applications subject to environmental and hazardous substance restrictions.

Base Product Number: DAC8564 and DAC8565 designations indicate different product lines within the same functional family. Both maintain identical electrical specifications and package compatibility.

Frequently Asked Questions (FAQ)

Q: Can DAC8564IAPWR be used as a direct replacement for DAC8564IDPWR?

A: Yes. DAC8564IAPWR is a parametric equivalent with identical electrical specifications, package footprint, and compliance certifications. The difference lies in packaging format (Cut Tape & Digi-Reel versus unspecified), which does not affect circuit functionality or PCB assembly compatibility.

Q: What is the difference between DAC8564 and DAC8565 base product numbers?

A: Both DAC8564 and DAC8565 maintain identical electrical performance, resolution, channel count, settling time, and output characteristics. The base product number distinction does not indicate functional differences relevant to substitution decisions.

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

A: Yes. All substitute parts use the 16-TSSOP package with identical pin configuration, footprint dimensions (0.173" × 4.40mm width), and surface mount technology. PCB layouts designed for DAC8564IDPWR require no modification for any listed substitute.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape & Digi-Reel and Tape & Reel formats are supply and handling methods only. They do not alter the electrical specifications, performance characteristics, or reliability of the integrated circuit itself.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry RoHS3 compliance and REACH unaffected certification, ensuring regulatory equivalence for applications subject to environmental restrictions.

Q: Can I mix different substitute part numbers in the same production batch?

A: Yes. All substitute parts maintain identical electrical specifications and package compatibility. However, traceability and quality documentation may require separate lot tracking depending on procurement and manufacturing requirements.
