DAC8555IPWG4 Equivalent & Substitute Parts

Part Overview

The DAC8555IPWG4 is a 16-bit digital-to-analog converter (DAC) manufactured by Texas Instruments, designed for data acquisition applications requiring four independent voltage output channels. This device features microPOWER™ architecture with a 10µs settling time and operates across a wide supply voltage range of 2.7V to 5.5V for both analog and digital domains.

The DAC8555IPWG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, maintenance, and new system implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC8555IPWG4 is determined by strict equivalence across the following critical parameters:

• Resolution: 16-bit digital input
• Channel Count: 4 independent D/A converters
• Output Configuration: Voltage output with buffering
• Interface Protocol: SPI and DSP compatibility
• Supply Voltage Range: 2.7V to 5.5V (both analog and digital)
• Linearity Specifications: INL/DNL of ±4 and ±0.25 LSB
• Settling Performance: 10µs maximum settling time
• Package Form Factor: 16-TSSOP surface mount
• Environmental Compliance: ROHS3 and REACH requirements

The DAC8554IPW meets all these criteria and qualifies as a parametric equivalent. Both devices share identical electrical specifications, architecture, and package geometry, enabling direct functional substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The DAC8554IPW is a direct parametric equivalent to the discontinued DAC8555IPWG4. Both devices are manufactured by Texas Instruments under the microPOWER™ series and maintain identical electrical and mechanical specifications.

The DAC8554IPW is currently in active production status with 1403 units available in inventory, providing immediate supply availability. Both parts carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for industrial and commercial applications.

The primary distinction between the two parts is packaging format: the DAC8555IPWG4 was supplied in standard packaging, while the DAC8554IPW is supplied in tube packaging. This difference does not affect electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DAC8554IPW directly replace the DAC8555IPWG4 in existing designs?

A: Yes. The DAC8554IPW is a parametric equivalent with identical electrical specifications, pin configuration, and package geometry. No circuit modifications are required for substitution.

Q: Are there differences in pin configuration between these parts?

A: No. Both devices use the 16-TSSOP package with identical pin assignments, signal definitions, and functional layout.

Q: What is the difference between the two part numbers?

A: The primary difference is the base product number designation (DAC8555 versus DAC8554) and packaging format (standard versus tube). The electrical and functional characteristics are identical.

Q: Is the DAC8554IPW suitable for the same operating temperature range?

A: Yes. Both parts operate across -40°C to 105°C, supporting identical thermal specifications for industrial and extended temperature applications.

Q: Do both parts require the same external reference voltage configuration?

A: Yes. Both devices use external reference type architecture and require identical external reference circuit design and component selection.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 1 - Unlimited).
