TLV5638CDG4 Equivalent & Substitute Parts

Part Overview

The TLV5638CDG4 is a 12-bit digital-to-analog converter (DAC) featuring dual voltage output channels with buffered outputs, designed for data acquisition applications. Manufactured by Texas Instruments, this component integrates SPI interface control with selectable internal or external voltage references, supporting dual supply voltage ranges of 2.7V to 3.3V or 5V for both analog and digital domains.

The TLV5638CDG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or redesign requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV5638CDG4 is determined by strict equivalence across the following critical parameters:

• 12-bit resolution with dual D/A converter channels
• Buffered voltage output configuration
• SPI serial interface protocol
• Dual supply voltage support (2.7V to 3.3V and 5V ranges)
• Identical settling time specification of 7µs
• Matching INL/DNL performance (±1.7, ±0.4 LSB)
• String DAC architecture
• 8-SOIC surface mount package with identical physical dimensions
• ROHS3 compliance and MSL Level 1 rating

The TLV5638CD meets all these criteria and qualifies as a direct substitute. The primary distinction is packaging format and product availability status.

Parameter Comparison

Engineering Selection Recommendations

The TLV5638CD is the direct substitute for the discontinued TLV5638CDG4. Both components are manufactured by Texas Instruments and maintain identical electrical specifications, performance characteristics, and physical package dimensions.

The TLV5638CD carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and MSL Level 1 rating, satisfying regulatory and environmental requirements.

The TLV5638CD is supplied in tube packaging, whereas the original part's packaging format is unspecified. This distinction does not affect functional compatibility or electrical performance in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the TLV5638CD directly replace the TLV5638CDG4 in existing designs?

A: Yes. The TLV5638CD is electrically and mechanically equivalent to the TLV5638CDG4. All functional parameters, pin configurations, and performance specifications are identical. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The TLV5638CDG4 is discontinued at DiGi Electronics. The TLV5638CD provides equivalent functionality with active product status and current availability.

Q: Are there any differences in compliance or environmental ratings?

A: No. Both components maintain ROHS3 compliance, MSL Level 1 rating, and identical regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001).

Q: Does packaging format affect circuit performance?

A: No. The TLV5638CD is supplied in tube packaging while the original part's packaging is unspecified. This is a supply and handling consideration only and does not impact electrical or mechanical performance.

Q: Are the pin configurations identical?

A: Yes. Both components use the 8-SOIC package with identical physical dimensions (0.154", 3.90mm width) and pin assignments.
