DAC8555IPWR Equivalent & Substitute Parts

Part Overview

The DAC8555IPWR is a 16-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, designed for data acquisition applications requiring four independent voltage output channels. The device features microPOWER™ architecture with a settling time of 10µs and operates across a wide supply voltage range of 2.7V to 5.5V for both analog and digital domains.

The DAC8555IPWR is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently utilizing this component.

Substitute Part Grouping Explanation

Substitute parts for the DAC8555IPWR are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Number of bits: 16
• Number of D/A converters: 4
• Output type: Voltage - Buffered
• Data interface: SPI, DSP
• Supply voltage range: 2.7V ~ 5.5V (both analog and digital)
• INL/DNL specifications: ±4, ±0.25 LSB
• Package type: 16-TSSOP
• Operating temperature range: -40°C ~ 105°C

The DAC8555IPWR has two identified substitutes: DAC8555IPW (manufacturer recommended) and DAC8554IPWR (parametric equivalent). Both parts maintain identical electrical specifications and package configuration, differing only in product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

DAC8555IPW is the manufacturer-recommended substitute for the obsolete DAC8555IPWR. This part maintains active product status with Texas Instruments, ensuring ongoing support and availability. All electrical parameters, package configuration, and compliance certifications (ROHS3, REACH Unaffected) are identical to the original part. The primary difference is packaging format (Tube versus Reel), which does not affect electrical performance or functional compatibility.

DAC8554IPWR is a parametric equivalent offering identical electrical specifications and performance characteristics. This part is also active and available in Cut Tape and Digi-Reel® packaging formats. Selection between DAC8555IPW and DAC8554IPWR depends on packaging requirements and supply chain availability.

Both substitutes are suitable for direct replacement in applications currently using the DAC8555IPWR, provided that packaging format and procurement quantities align with system requirements.

Frequently Asked Questions (FAQ)

Q: Can DAC8555IPW be used as a direct replacement for DAC8555IPWR?

A: Yes. DAC8555IPW is the manufacturer-recommended substitute with identical electrical specifications, pin configuration, and package type (16-TSSOP). The only difference is packaging format (Tube instead of Reel), which does not affect functional compatibility or performance.

Q: What is the difference between DAC8555IPW and DAC8554IPWR?

A: Both parts are parametric equivalents with identical electrical specifications, settling time, resolution, and operating characteristics. The primary difference is the base product number (DAC8555 versus DAC8554) and packaging format. DAC8554IPWR is available in Cut Tape and Digi-Reel® formats, while DAC8555IPW is supplied in Tube format.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 16-TSSOP package with identical pin assignments, enabling direct PCB-level substitution without layout modifications.

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

A: Yes. Both DAC8555IPW and DAC8554IPWR are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited), matching the original DAC8555IPWR specifications.

Q: Why is the DAC8555IPWR classified as obsolete?

A: The DAC8555IPWR has reached end-of-life status with Texas Instruments. Active alternatives (DAC8555IPW and DAC8554IPWR) are available to support ongoing design requirements and supply chain continuity.

Q: Which substitute should be selected for new designs?

A: For new designs, either DAC8555IPW or DAC8554IPWR is appropriate. Selection should be based on packaging format requirements and procurement availability. Both parts are active products with full manufacturer support.
