DAC8554IPWG4 Equivalent & Substitute Parts

Part Overview

The DAC8554IPWG4 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 component features a microPOWER™ architecture with SPI/DSP interface compatibility and operates across a wide supply voltage range of 2.7V to 5.5V for both analog and digital domains.

The DAC8554IPWG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the DAC8554IPWG4 is determined by strict equivalence across the following critical parameters:

  • Resolution and Channel Count: 16-bit resolution with 4 independent D/A converters
  • Output Characteristics: Voltage-buffered output with external reference capability
  • Interface Protocol: SPI and DSP data interface compatibility
  • Electrical Performance: Settling time of 10µs, INL/DNL specifications of ±4 and ±0.25 LSB
  • Supply Voltage Range: Dual supply rails supporting 2.7V to 5.5V for both analog and digital domains
  • Package Specification: 16-TSSOP surface mount package with identical physical dimensions
  • Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The DAC8554IPW meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is packaging format and product status.

Engineering Selection Recommendations

The DAC8554IPW is the recommended substitute for the discontinued DAC8554IPWG4. Both parts share identical electrical specifications, performance characteristics, and physical package dimensions. The DAC8554IPW maintains active product status with Texas Instruments and carries full ROHS3 compliance and MSL Level 1 certification.

The distinction between these parts is limited to packaging format: the DAC8554IPWG4 is supplied in tape and reel configuration, while the DAC8554IPW is supplied in tube packaging. This packaging difference does not affect electrical performance, pin compatibility, or functional operation within the circuit design.

Selection of the DAC8554IPW ensures continued access to a functionally equivalent component with verified availability and active manufacturer support.

Frequently Asked Questions (FAQ)

Q: Are the DAC8554IPWG4 and DAC8554IPW pin-compatible?

A: Yes. Both parts use the 16-TSSOP package with identical pin assignments, electrical characteristics, and functional specifications. Direct substitution is possible without circuit modification.
