DAC53508RTER Equivalent & Substitute Parts

Part Overview

The DAC53508RTER is a 10-bit digital-to-analog converter manufactured by Texas Instruments, designed for data acquisition applications requiring multiple simultaneous voltage outputs. This device integrates eight independent D/A converters in a compact 16-WQFN surface-mount package with an exposed pad for thermal management. The part operates across a wide supply voltage range of 1.8V to 5.5V for both analog and digital domains, making it suitable for mixed-signal system designs.

The DAC53508RTER is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified based on identical electrical performance specifications, package geometry, and functional architecture. Alternative part numbers may be required due to packaging format availability, inventory constraints, or supply chain considerations.

Substitute Part Grouping Explanation

Substitution eligibility for the DAC53508RTER is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish the substitution criteria:

Electrical Equivalence Parameters:

• 10-bit resolution with 8 independent D/A converters
• 10µs settling time performance
• Buffered voltage output configuration
• Serial SPI data interface
• External reference architecture
• ±1 LSB maximum INL and DNL specifications
• 1.8V to 5.5V dual supply voltage range
• String DAC architecture
• -40°C to 125°C operating temperature range

Mechanical Equivalence Parameters:

• 16-WQFN (3x3) package with exposed pad
• Surface-mount technology
• RoHS3 compliance
• MSL Level 1 rating

The DAC43508RTER qualifies as a parametric equivalent substitute based on identical electrical specifications and package geometry. The primary distinction between these parts is the packaging format: the DAC53508RTER is supplied in Tape & Reel (TR) format, while the DAC43508RTER is available in Cut Tape (CT) and Digi-Reel® format. Both parts share identical functional performance and are manufactured by Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

The DAC43508RTER is a direct functional equivalent to the DAC53508RTER for all electrical and thermal performance requirements. Both parts are active products manufactured by Texas Instruments with identical RoHS3 compliance and MSL Level 1 ratings, ensuring equivalent reliability and environmental compliance across applications.

Selection between these parts is determined by packaging and supply chain requirements rather than functional performance:

DAC53508RTER (Tape & Reel format): Suitable for high-volume automated assembly operations where continuous reel feeding is required. This format is optimized for pick-and-place equipment with standard reel specifications.

DAC43508RTER (Cut Tape & Digi-Reel® format): Suitable for mixed-volume production, prototyping, and applications where flexible packaging quantities are required. Cut tape format accommodates manual or semi-automated assembly processes.

Both parts deliver identical electrical performance across the full operating temperature range of -40°C to 125°C and maintain equivalent signal integrity specifications. The choice between these substitutes depends solely on manufacturing process requirements and inventory management strategy.

Frequently Asked Questions (FAQ)

Q: Are the DAC53508RTER and DAC43508RTER electrically interchangeable?

A: Yes. Both parts are manufactured by Texas Instruments with identical 10-bit resolution, 8 D/A converter channels, 10µs settling time, buffered voltage output, SPI serial interface, and ±1 LSB INL/DNL specifications. They operate across the same 1.8V to 5.5V supply voltage range and share identical -40°C to 125°C temperature performance.

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

A: The primary difference is packaging format. The DAC53508RTER is supplied in Tape & Reel (TR) format for high-volume automated assembly. The DAC43508RTER is supplied in Cut Tape (CT) and Digi-Reel® format for flexible quantity requirements and mixed-volume production.

Q: Can I use DAC43508RTER in place of DAC53508RTER in my PCB assembly?
