TLV5617ACDG4 Equivalent & Substitute Parts

Part Overview

The TLV5617ACDG4 is a 10-bit digital-to-analog converter (DAC) featuring dual output channels with buffered voltage output, designed for data acquisition applications. The device operates across dual supply ranges (2.7V to 3.3V or 5V) and communicates via SPI interface with an external voltage reference. This part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV5617ACDG4 is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Count: 10-bit resolution with 2 D/A converters
• Output Configuration: Buffered voltage output with external reference
• Communication Protocol: SPI digital interface
• Supply Voltage Compatibility: Dual supply operation at 2.7V–3.3V or 5V for both analog and digital domains
• Accuracy Specifications: INL/DNL performance of ±0.7 LSB and ±0.1 LSB respectively
• Settling Time: 10µs maximum settling time
• Package Compatibility: 8-SOIC surface mount package with 0.154" (3.90mm) width
• Environmental Compliance: ROHS3 compliance and MSL Level 1 rating

The TLV5617ACD meets all these criteria and is classified as a direct manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The TLV5617ACD is the direct substitute for the TLV5617ACDG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, pin configurations, and package geometry. The primary distinction is product status: the TLV5617ACDG4 is discontinued, while the TLV5617ACD maintains active production status with significantly higher inventory availability (17,800 units versus 1,084 units).

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and legacy system support. The TLV5617ACD is supplied in tube packaging, which is standard for active production components. No design modifications, firmware updates, or board layout changes are required when transitioning from the TLV5617ACDG4 to the TLV5617ACD.

Frequently Asked Questions (FAQ)

Q: Can the TLV5617ACD be used as a direct replacement for the TLV5617ACDG4?

A: Yes. Both parts are electrically and mechanically identical. The TLV5617ACD is the manufacturer-recommended substitute and requires no design changes.

Q: Are there differences in pin configuration or package dimensions?

A: No. Both parts use the 8-SOIC package with identical 0.154" (3.90mm) width and pin assignments. PCB layouts and footprints are fully compatible.

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

A: The primary difference is product lifecycle status. The TLV5617ACDG4 is discontinued, while the TLV5617ACD is in active production. The suffix variation reflects packaging or date code designations but does not affect functional performance.

Q: Are supply voltage requirements identical?

A: Yes. Both parts operate with identical analog and digital supply ranges of 2.7V–3.3V or 5V, with no restrictions on mixed-voltage operation within these ranges.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity) ratings.

Q: Is the SPI interface protocol identical between the two parts?

A: Yes. Both parts use identical SPI communication protocols with external voltage reference configuration. No firmware or software modifications are required.
