DAC8565IBPWRG4 Equivalent & Substitute Parts

Part Overview

The DAC8565IBPWRG4 is a 16-bit digital-to-analog converter (DAC) with four independent channels, designed for precision voltage output applications. Manufactured by Texas Instruments, this component features buffered voltage outputs, SPI/DSP data interfaces, and operates across a 2.7V to 5.5V supply range. The part is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and design requirements. Active alternatives with identical electrical and mechanical specifications are available to maintain design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC8565IBPWRG4 is determined by strict equivalence across the following critical 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
• 16-TSSOP surface mount package
• ROHS3 compliance and MSL Level 1 rating

All substitute parts maintain identical electrical performance and mechanical compatibility. Differences exist only in product status (active vs. discontinued) and packaging format (cut tape, tape & reel, or bulk).

Parameter Comparison

Engineering Selection Recommendations

The DAC8565IBPWRG4 is discontinued and should be replaced with active alternatives. The primary substitute is DAC8565IBPWR, which maintains identical specifications and is currently in active production status with higher inventory availability (1593 units). This part is the direct functional equivalent with no electrical or mechanical differences.

For applications requiring alternative packaging formats, DAC8564IAPWR (cut tape & Digi-Reel) and DAC8564ICPWR (tape & reel) provide equivalent performance with different supply chain configurations. DAC8565IAPWR offers the same base product line with cut tape packaging and the highest inventory level (3400 units).

All substitute parts carry ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage requirements. Selection between alternatives should be based on packaging availability and supply chain logistics rather than electrical performance, as all parts are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can DAC8565IBPWR be used as a direct replacement for DAC8565IBPWRG4?

A: Yes. DAC8565IBPWR is electrically and mechanically identical to DAC8565IBPWRG4. The only difference is product status (active vs. discontinued) and packaging format. No circuit modifications are required.

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

A: Both variants are 16-bit, 4-channel DACs with identical electrical specifications, settling time, supply voltage ranges, and INL/DNL performance. The suffix letters (I, A, B, C) indicate temperature grade and packaging format variations. All are functionally equivalent for this application.

Q: Are packaging format differences (cut tape, tape & reel, bulk) electrically significant?

A: No. Packaging format affects only supply chain handling and storage. The silicon die and electrical performance are identical across all packaging options. Selection should be based on manufacturing process requirements and inventory availability.

Q: Is the 16-TSSOP package compatible with existing PCB layouts?

A: Yes. All substitute parts use the identical 16-TSSOP package (0.173" width, 4.40mm). PCB footprints, solder reflow profiles, and assembly processes require no modification.

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

A: Yes. All listed substitutes are ROHS3 compliant with MSL Level 1 rating. REACH status is unaffected across all variants, and ECCN classification remains EAR99 for all parts.

Q: Which substitute part should be selected for new designs?

A: DAC8565IBPWR is recommended for new designs due to active production status and adequate inventory. For high-volume requirements, DAC8565IAPWR offers the largest available stock (3400 units) with identical electrical performance.
