Key Parameters

Substitute Part Grouping Explanation

Substitution of the THS4130CDGN is determined by equivalence across the following critical parameters:

Functional Parameters:

• Amplifier type (Differential)
• Number of circuits (1)
• Output type (Differential)
• Slew rate (52 V/µs)
• Gain bandwidth product (225 MHz)
• -3dB bandwidth (150 MHz)

Electrical Parameters:

• Input bias current (2 µA)
• Input offset voltage (200 µV)
• Output current per channel (85 mA)

Physical Parameters:

• Package type (8-HVSSOP)
• Mounting type (Surface Mount)
• Pin configuration compatibility

The THS4130IDGNR is identified as a manufacturer-recommended substitute based on matching all functional, electrical, and physical parameters. Differences in product status, operating temperature range, supply voltage span, and supply current are secondary considerations that do not affect core substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The THS4130IDGNR is the manufacturer-recommended substitute for the obsolete THS4130CDGN. Selection of this substitute is based on the following engineering criteria:

Functional Equivalence: All core amplifier specifications are identical, including slew rate, gain bandwidth product, bandwidth, input bias current, input offset voltage, and output current capability. Pin configuration and package dimensions are identical.

Product Status: The THS4130IDGNR maintains active product status with Texas Instruments, ensuring ongoing availability and manufacturing support. The THS4130CDGN is obsolete, making the active substitute the appropriate choice for new designs and production continuity.

Compliance and Certifications: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1). No regulatory or environmental compliance barriers exist to substitution.

Operating Conditions: The THS4130IDGNR provides an extended operating temperature range (-40 to 85°C versus 0 to 70°C) and expanded supply voltage span (4 to 33 V versus 5 to 30 V). These expanded specifications do not create incompatibility and provide additional design flexibility.

Supply Current: The THS4130IDGNR operates at 12.3 mA versus 14 mA for the main part, representing a reduction in power consumption with no functional impact.

Frequently Asked Questions (FAQ)

Q: Can the THS4130IDGNR be used as a direct replacement for the THS4130CDGN in existing designs?

A: Yes. The THS4130IDGNR is electrically and mechanically equivalent to the THS4130CDGN across all critical parameters. Pin configuration, package dimensions, and functional specifications are identical. Direct substitution is supported without circuit modification.

Q: What is the difference in operating temperature range between these parts?

A: The THS4130CDGN operates from 0 to 70°C, while the THS4130IDGNR operates from -40 to 85°C. The substitute part has an extended temperature range. For applications operating within the original 0 to 70°C range, both parts are functionally equivalent.

Q: Are there differences in supply voltage requirements?

A: The THS4130CDGN requires a supply voltage span of 5 to 30 V. The THS4130IDGNR accepts 4 to 33 V. The substitute part has a wider acceptable voltage range. Both parts are compatible with standard ±5 V, ±12 V, and ±15 V dual supply configurations.

Q: Why does the THS4130IDGNR have lower supply current?

A: The THS4130IDGNR operates at 12.3 mA versus 14 mA for the THS4130CDGN. This represents improved power efficiency in the active substitute. Lower supply current does not affect output capability or signal integrity.

Q: Is the packaging identical between these parts?

A: Yes. Both the THS4130CDGN and THS4130IDGNR use the 8-HVSSOP package with 8-TSSOP/8-MSOP footprint (0.118", 3.00mm width) with exposed pad. PCB layout and assembly processes require no modification.

Q: What is the significance of the THS4130CDGN being obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued manufacturing of the THS4130CDGN. The THS4130IDGNR is the active equivalent and is the appropriate choice for new production, design updates, and long-term supply chain planning.

Q: Are both parts RoHS compliant?

A: Yes. Both the THS4130CDGN and THS4130IDGNR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
