DAC8565IDPWR Equivalent & Substitute Parts

Part Overview

The DAC8565IDPWR 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 operates across a wide supply voltage range of 2.7V to 5.5V for both analog and digital domains, with a settling time of 10µs and buffered voltage outputs. The device is housed in a 16-TSSOP surface mount package and maintains ROHS3 compliance with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified when applications require alternative packaging formats, inventory availability, or identical electrical performance specifications while maintaining full functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAC8565IDPWR 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 identical:

• 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 supply voltage range for both analog and digital domains
• ±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 with identical physical dimensions
• ROHS3 compliance and MSL Level 1 rating

The identified substitute parts include DAC8564IAPWR, DAC8564ICPWR, DAC8565IAPWR, and DAC8565IBPWR. These parts maintain complete electrical equivalence while differing only in packaging format (Cut Tape & Digi-Reel, Tape & Reel) or minor device variant designations that do not affect functional performance.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status with Texas Instruments, ensuring continued availability and technical support. Each substitute part carries ROHS3 compliance and MSL Level 1 rating, meeting the same environmental and regulatory requirements as the primary DAC8565IDPWR device.

Selection between the DAC8565IDPWR and its substitutes should be based on packaging format availability and supply chain requirements:

DAC8564IAPWR and DAC8565IAPWR are available in Cut Tape & Digi-Reel packaging format, suitable for applications requiring flexible quantity handling and automated assembly processes.

DAC8564ICPWR is supplied in Tape & Reel format, optimized for high-volume production environments with standardized reel-based component feeding systems.

DAC8565IDPWR and DAC8565IBPWR are available in standard packaging configurations, appropriate for general procurement and prototyping applications.

All parts share identical electrical performance, thermal characteristics, and compliance certifications, enabling direct substitution without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can DAC8564IAPWR replace DAC8565IDPWR in production designs?

A: Yes. Both devices are parametrically equivalent 16-bit, 4-channel digital-to-analog converters with identical electrical specifications, operating temperature range, and package dimensions. The primary difference is packaging format. DAC8564IAPWR is supplied in Cut Tape & Digi-Reel format while DAC8565IDPWR uses standard packaging.

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

A: The base product numbers indicate device variants within the same family. Both DAC8564 and DAC8565 variants maintain identical 16-bit resolution, 4-channel configuration, settling time, and electrical performance specifications. Substitution between these variants is valid based on parametric equivalence.

Q: Are packaging format differences significant for PCB assembly?

A: Packaging format differences (Cut Tape & Digi-Reel, Tape & Reel, standard) affect supply chain logistics and automated assembly compatibility but do not impact electrical performance or physical footprint. All substitute parts use the identical 16-TSSOP surface mount package with 0.173" width and 4.40mm dimensions.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All identified substitute parts carry ROHS3 compliance, MSL Level 1 rating, and active product status. They meet identical environmental and regulatory standards as the primary DAC8565IDPWR device.

Q: Can I substitute DAC8565IBPWR for DAC8565IDPWR without circuit modifications?

A: Yes. DAC8565IBPWR is a direct parametric equivalent with identical electrical specifications, reference configuration, data interface support, and operating characteristics. No circuit modifications are required for substitution.

Q: What inventory considerations apply when selecting substitute parts?

A: Substitute part availability varies: DAC8565IAPWR has 3400 units in stock, DAC8565IBPWR has 1593 units, DAC8564IAPWR has 2052 units, and DAC8564ICPWR has 1079 units. Selection should account for project timeline and quantity requirements.
