TLV2548QDWR Equivalent & Substitute Parts

Part Overview

The TLV2548QDWR is a 12-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for data acquisition applications requiring 8 single-ended inputs with a 200 kSPS sampling rate. The device operates across a 3V to 5.5V supply range and communicates via SPI interface, making it suitable for embedded systems and industrial measurement applications.

The TLV2548QDWR maintains Active product status with robust inventory availability. Identifying equivalent and substitute parts is essential for supply chain continuity, design flexibility, and long-term project sustainability when the primary part becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitute parts for the TLV2548QDWR are identified based on strict parametric equivalence across the following critical criteria:

• 12-bit resolution matching the original specification
• 200 kSPS sampling rate capability
• 8 single-ended input channels
• SPI digital interface protocol
• SAR architecture configuration
• Dual reference support (External and Internal)
• 3V to 5.5V supply voltage compatibility
• 20-SOIC package form factor
• Surface mount mounting technology
• Operating temperature range of -55°C to 125°C

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign or firmware modification.

Parameter Comparison

Engineering Selection Recommendations

The TLV2548QDWRG4 is a direct parametric equivalent to the TLV2548QDWR and qualifies as a suitable substitute based on identical electrical specifications, package form factor, and compliance certifications. Both parts share the same base product number (TLV2548) and maintain equivalent RoHS3 compliance, MSL rating, REACH status, and trade classification codes.

The primary distinction is product status: the TLV2548QDWR maintains Active status with 844 units in stock, while the TLV2548QDWRG4 is Discontinued at DiGi Electronics with 887 units available. For new designs or long-term production requirements, the TLV2548QDWR is the preferred selection due to its active status and ongoing manufacturer support. The TLV2548QDWRG4 may be considered for immediate fulfillment of existing inventory or as a temporary alternative when primary part availability is constrained.

Frequently Asked Questions (FAQ)

Q: Can the TLV2548QDWRG4 be used as a direct replacement for the TLV2548QDWR in existing designs?

A: Yes. Both parts are parametrically identical across all electrical, functional, and mechanical specifications. No circuit redesign, firmware modification, or PCB layout changes are required. The parts are pin-compatible and functionally interchangeable.

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

A: The TLV2548QDWRG4 includes a suffix designation (G4) that typically indicates a specific manufacturing date code or distribution channel variant. The core device functionality, specifications, and performance characteristics are identical to the TLV2548QDWR.

Q: Are both parts available in the same package?

A: Yes. Both the TLV2548QDWR and TLV2548QDWRG4 are supplied in the 20-SOIC (0.295", 7.50mm Width) surface mount package with identical pinout and mechanical dimensions.

Q: What compliance certifications apply to both parts?

A: Both parts maintain ROHS3 compliance, carry an MSL rating of 1 (Unlimited moisture sensitivity), are REACH Unaffected, and share the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Why would I choose one part over the other?

A: The TLV2548QDWR is recommended for new designs and long-term production due to its Active product status and ongoing manufacturer support. The TLV2548QDWRG4 may be selected when immediate availability is prioritized or when existing inventory must be utilized, provided that the discontinued status does not conflict with project lifecycle requirements.
