TLV5638CDRG4 Equivalent & Substitute Parts

Part Overview

The TLV5638CDRG4 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 both external and internal reference voltage options, supporting dual supply voltage ranges of 2.7V to 3.3V and 5V.

The TLV5638CDRG4 is currently discontinued at DiGi Electronics. Locating equivalent substitute parts is necessary to maintain design continuity and ensure project timelines are not compromised. Substitute components must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitute parts for the TLV5638CDRG4 are identified based on strict parametric equivalence across the following critical criteria:

• Resolution and Channel Count: 12-bit resolution with 2 D/A converters
• Output Configuration: Voltage output with buffered stage
• Interface Protocol: SPI digital interface
• Reference Architecture: Support for both external and internal reference voltages
• Supply Voltage Compatibility: Dual supply ranges of 2.7V to 3.3V and 5V for both analog and digital domains
• Performance Specifications: Settling time of 7µs, INL/DNL specifications of ±1.7 and ±0.4 LSB
• Package Compatibility: 8-SOIC surface mount package with 0.154" (3.90mm) width
• Regulatory Compliance: ROHS3 compliance and MSL Level 1 rating

Substitutes must match all parameters listed above without exception. Packaging variants (Cut Tape, Digi-Reel) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TLV5638CDR serves as the direct parametric equivalent to the discontinued TLV5638CDRG4. Both components are manufactured by Texas Instruments and share identical electrical specifications, performance characteristics, and mechanical packaging.

The primary distinction between these parts is product status: the TLV5638CDRG4 is discontinued, while the TLV5638CDR maintains active production status with significantly higher inventory availability (20,108 units in stock versus 678 units for the discontinued variant). Both components maintain ROHS3 compliance and identical regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001).

For new designs or component replenishment, the TLV5638CDR is the recommended selection due to sustained manufacturing support and supply chain availability. The packaging variant difference (Cut Tape and Digi-Reel for TLV5638CDR) does not affect electrical performance or PCB assembly compatibility.
